shell-model calculations, the problems can be solved analytically. The
results, however, will be in worse agreement with experiment than for
blurred potentials. A method is described for calculating both the
nuclear energy levels and the cross sections. The potential V(r) can be Ix

The application of thin method to problem@ involving the passage of neutrons andgamma
quanta through a substance is possible due to the absence of any Interrelation between the
particles In real beams. The difficulties that arise In connectim with the use of the Monte
Carlo method are concerned primarily with the determination of small probabilities. In
problems connected with the passage of radiation through a substance, the smallness of
the probability p may be occasioned by the absorption of the particles, their leakage from
the medium, energy losses as the result of slowing, etc. It Is pointed out that the Neuman
series for the solution of the kJnetic equation reduces the radiation transfer problem to
the computation of mgltiple Intervals, while the Monte Carlo method itself ponsists
essentially in the calculation of the terms of a Neuman series which dxe the multiple
intervals. Thia use of non-random points, in the opinion of the authors, Implies a repudiation
of the probabilities of the Monte Carlo scheme, eliminating the possibility of a practical
evaluation of the accuracy of the results. In those cases In which Interest attaches to a
particular functional of the kinetic equation solution, the methods which are described
In this article for increasing the statIBUcal effectiveness of the method normally provide an
accuracy quite satisfacory for practical purposes with a number of bligtories ranging from

ABSTRACT: The authors consider some procedural problems associated vith the compila-
tion of programs for solving problems in nuclear radiation shielding by the Monte
Carlo method. There are two classical approaches in using this method for calculating
the passage of radiation through matter: 1. modeling the behavior ot a neutron or y-
quantum in the medium and 2. writing out the solution for the ititegral equation of ra-,
diation transfer in the form of an infinite series with terma which wre multiple inte-
grals of increasingly higher order (Neumann series) with subsequent application of th9d
Monte Carlo method for calculating these tenus. Two probleino ai*e considered: t1le gen
eral structure of a program for shielding calculation and the structure of an elemen-
tary unit for general shielding geometry. It is assumed in the cliscussion that the

The article introduces a graphical method of sol-Ving a series of
problems which are encountered in an investigation of the geometry of a
Cardan suspension. -The method makes use of a stereographic ptojection and
is based on the method of analysis employed by V. V. Dobrovollskiy in hie
work., Teopiya. Sfericheskikh Mekhanizm . (The Theory of Spherical Mecha-
nisms),, Moscow, 19117.
The author first locates the stereographic image normal to the plane
of a Carden ring on a reference plane connected to a stationary basej then
determines the angle of inclination of a second Carden iing in relation to
the stationary base; next he determines the angle betwen the swinging axes
of the Cardan rings and the line of intersection of the Dlane or thp second
Cardan ring and the plane connected to the stationary base. Then be 1=tes,

which are in mutually unique correlation vith geometric
figures given on a spherical surface. The plane coincides
with that of one of the great circles. The methods used

BSTRACT: The authors developed a method for the deterudnation of the in-
fluence exercised by the liquid medium upon the impact fatigue re-
sistance of steel and carried out a corresponding investigation. The
scheme of a machine and the experimental method are described. The
recorded curves for continuous impact strength of the case-hardened
samples are given in form of the dependence of a nunber of impacts
until destruction upon the energy of the single impaci. It is shown
that the most resistant steel in the case-hardened state both in the
air and in the liquid medium in the steel 20 XM3A. From a comparison
of the curves obtained when investigating in the solution and in the
air, it may be seen that in the case of all types or steel a decrease
of impaot-fatigue-strangth may be observed when investigation is
carried out in the solution. In the case of short investigations
(20-40 min.) in the liquid medium this decrease amounted to 38-42%,
in the case of tests of long duration (45-50 hours) it amounts to
53-55%. In order to detemine the influence exercined by the compo-

comparative impaot-fatigue-tests were carried out with case-hardened
samples of 12 KW2A steel in pure distilled water, in the air, and
in a solution. It is shown that the greatest decrease of impact
strength was obser7ed in the case of the test carried out in the
solution. The investigation of the destroyed sample showed that the
working surface of the sample had no oxide film an a result of a
test carried out in distilled water, in contrast to the surface
obtained by the investigation carried out in the solution. It is
assumed that, besides the phenomena of the adsorption and strutting
effect, the reduction of impact strength Is caused also by the
affect of corrosion. In the came of short experiments the effect of
corrosion is of no importance, but with an increase of the duration
of the experiment the role played by it increases steadily. The data
obtained agree well with the testa carried cALt in nature with
drilling milling cutters ( the latter developed in a liquid medium
under cyclical impact streesee). There arc ) fiVires, i table and

ABSTRACT: Factors affecting the destruction of cutters of drilling bits
(CDB) were investigated and a number of requirements which
must be satisfied by steels of which tho CDR are made were
developed. Comparative impact-strength testt; were performed
on .11 different types of steel. It was established that the in-
crease in impact strength; produced during surface hardening
of the CDB by means of cementation, is decisively affected by
the strength of the carburized layer (CL), rather than by the
magnitude and nature of distribution of the residual and surface
stresses. It is therefore essential that sucn alloying elements

sion function of the linear part of the extrapolating de-
vice can be found by the application of the usual (and not
discreet) Laplace transformation. Thko tronamission function
only expresses the connection between the representation of
the input and the output quantity in the case of a certain
shape of the input action - in the case of a continuity of
the rectangular pulses with r w 1. Therefore such a func-
tion can be called a conditional transmission function.
3) On the basis of the data given here it can be stated
that the method of the conditional transmission functions
(in the sense here mentioned) is applicable when the input
action represents a continuity of impulses of any previously

ABSTRACT: The author investigated the influence of the tempering
temperature on /the impact fatigue strength of 30KhGS steel
(0 60716 Mn, 1.20916 Cr and 0.99% Si). The impact

as shown in Pigure 2 was subjected to pure impact bending
(the load was applied simultaneously at two points with
impact energies of 25 and 60 kgcm) with a frequency of
600 impacts/iain. After each impact, the sDecimen was

and the impact strength was determined bv means of a
pendulum impact-testing machine with an impact energy
of 30 kgm. The obtained results, graphed in Figure 3,
show that all the mechanical properties, i.e. strength,
impact strength, and impact fatigue strength increase
in the case of tempering at 200 C. For tempering
temperAtures above 200 C, the strength and yield point
values dropqbgJmpact strengtg drops sharply at tempering
temperatures from 290to 500 C. However, for a tempering
temperature of 500 C, there is an increase in the
impact strength. In contrast to this, 811e impact fatigue
strength shows a second 4- at 400 C when the impact
strength is lowest aad at 500 C the impact fatigue
strength drops sharply. In the cage of impacts of
60 kgcm specimens tempered at 400 0 withstand the largest
number of impacts, whilst in the case of impacts with
energies of 25 kgcm, the specimens tempored at 200 C
withstand the largest number of impacts,, It was found
that for this steel, the fatigue strength in the case of

ABSTRACT: The aim of the work described in this paper was to establish
the influence of the steel composition and also of the depth
and the structure of the carburized layer on the magnitude and
the character of the distribution of the residual stresses in
carburized components. The influence of allo:ying elements and
of the carbon contents on the residual stresses in carb-urizzd
and heat-treated specimens was investigated on alloy and carbon
steels with compositions as given in the table on p 42. Cyl-
ind ical specimens of 12 mm dia, 150 mm length, were investi-
gated after being carburized in-a mixture of 8% chascoal 10%
sodium carbonate and 5% barium carbonate at 910-920 C for
durations of 3-20 hours. Immedia-tely after removal from the
carburization boxes, the specimens were quencheg in oil and
quenched for a seoond time in oil from 780-800 G. gollowing

1) The. magnitude' of the resIdual stresseo axid the character of
their distribution along the i~rcss-sectioii of the quenched,

layer as well as on the c.-hemical composition of the steel.
2) Yn increasing the depth of the carburised layer from
0.6-2.2 mm, the magnitude of the residual surface stressea
changes greatly. In the case of relatively shallow ca:Tb1ir:,.z--
ation depths, there are compression stresses at the surfa,,,e of
the specimens wh.-1.,-,h tn,:~rease- with increasing depth of -carburiz-

3) In accordance with the changes ia the residual surface
stresses, there will also be changes in the magnitude and
the character of the stresses along the cross-section of
the carburi2gd specimens. If the depth of carburization
does not exceed 1.2 mm., there will be a continuous change
in the residual stresses aloug the aross-section.
However, if the carburization depth exceeds 2 mm, the
curve representing the distribution of the
residual stresses will show a discou'Un-mity in the
compression stresses.
4) The magnitude and the character of the residual

shaft (700 rpm). Samples in the form of coe wheels (Fig 2) were
tested; in this case the jolting effoot (in. addition to the ef-
fect of friction caused by the rotation) was conveyed by the
cogs. White electro-corundum (0.6-0.0 mm), corundum (3-5 mm),
and quartz sand, in a liquid with a composition nimilar to sea

The conducted tests proved that the max1mum hardne.9s
of stainless steel (without case hardening) after
quenching from 1,000-1,5000 C is not over 30 RC,
while after case hardening it jr~creases to 55-60
RC. The steel which was case hardened at 950' C
differs very little (in hardnese) from the steel
case hardened at 1,0000 C. Therefore, the authors
recommend case hardening componentsmade from
stainless steels lKhl3 ang M17 at 9500 C and
quenching them from 1,000 C. There are 2 figures;

A13STRACT: The thormiordo emission of uranium dodeca)tarldeiias measured by a pro-
described earlier (Radiotekhnika I eloktronika v. 7P 2099. 3.9622). The sub-
:strate was a tungsten ribbon, on which.a thin layer (30 -- 50 ) of a dense sus-
wpension of U 12 powder in metal alcohol was deposited. As in the case of hoxaboride
~of rare earth motqlsp UB12 reacts with the tungsteno causing the latter to curl,
and causing mot, -,Io uranium to be depoaited on the walls of the bulb. The work
,function was determined from the measurod values of tho temporature and current
~density and is found to satisfy the equation 2.89 + 2.3 x 10-4 T. Deviations from a':
'linear dependence# towards lower values of the work function, are observed at 1500
1900 K and are Probably due to the start of noticeablo rosotion betwoen UB12 and

;;Of the anode cumnt was reached. Attcmpts to cover the UB12 MM With irldi
Aer were also unsuccessful. Comparison with the data on UB4 and TJB~2 in e t
f~the deviation from linearity at high temporaturos-can be attributed to gradual

The application of thin method to problem@ involving the passage of neutrons andgamma
quanta through a substance is possible due to the absence of any Interrelation between the
particles In real beams. The difficulties that arise In connectim with the use of the Monte
Carlo method are concerned primarily with the determination of small probabilities. In
problems connected with the passage of radiation through a substance, the smallness of
the probability p may be occasioned by the absorption of the particles, their leakage from
the medium, energy losses as the result of slowing, etc. It Is pointed out that the Neuman
series for the solution of the kJnetic equation reduces the radiation transfer problem to
the computation of mgltiple Intervals, while the Monte Carlo method itself ponsists
essentially in the calculation of the terms of a Neuman series which dxe the multiple
intervals. Thia use of non-random points, in the opinion of the authors, Implies a repudiation
of the probabilities of the Monte Carlo scheme, eliminating the possibility of a practical
evaluation of the accuracy of the results. In those cases In which Interest attaches to a
particular functional of the kinetic equation solution, the methods which are described
In this article for increasing the statIBUcal effectiveness of the method normally provide an
accuracy quite satisfacory for practical purposes with a number of bligtories ranging from

ABSTRACT: The authors consider some procedural problems associated vith the compila-
tion of programs for solving problems in nuclear radiation shielding by the Monte
Carlo method. There are two classical approaches in using this method for calculating
the passage of radiation through matter: 1. modeling the behavior ot a neutron or y-
quantum in the medium and 2. writing out the solution for the ititegral equation of ra-,
diation transfer in the form of an infinite series with terma which wre multiple inte-
grals of increasingly higher order (Neumann series) with subsequent application of th9d
Monte Carlo method for calculating these tenus. Two probleino ai*e considered: t1le gen
eral structure of a program for shielding calculation and the structure of an elemen-
tary unit for general shielding geometry. It is assumed in the cliscussion that the
reader is familiar with the Monte Carlo method as presented in works by Buslenko,

Zolotukhin, Vladimirov and others where it'is shown that penetration of radiation
through matter may be given in terms of the phase coordinates of the particles along
its trajectory. A procedure is described for compiling a program to follow this tra-
jectory. Particular emphasis is given to that part of the program for det;.--.-Taining the
distances travelled by the particle in moving from a given point in a given direction
before exit frcm the medium. An algorithm in ALGOL-60 language is given in the form ol
a procedure for determining these distances and correlating the corresponding numbers.
The resulting gecimetric unit may be useful in other computaticoal methods, e. g. for
constructing three-dimensional nets for difference methods. OrIg. art. has: I formu-

The article introduces a graphical method of sol-Ving a series of
problems which are encountered in an investigation of the geometry of a
Cardan suspension. -The method makes use of a stereographic ptojection and
is based on the method of analysis employed by V. V. Dobrovollskiy in hie
work., Teopiya. Sfericheskikh Mekhanizm . (The Theory of Spherical Mecha-
nisms),, Moscow, 19117.
The author first locates the stereographic image normal to the plane
of a Carden ring on a reference plane connected to a stationary basej then
determines the angle of inclination of a second Carden iing in relation to
the stationary base; next he determines the angle betwen the swinging axes
of the Cardan rings and the line of intersection of the Dlane or thp second
Cardan ring and the plane connected to the stationary base. Then be 1=tes,

termines the angles between the plane of the second Cardan ring and the

BSTRACT: The authors developed a method for the deterudnation of the in-
fluence exercised by the liquid medium upon the impact fatigue re-
sistance of steel and carried out a corresponding investigation. The
scheme of a machine and the experimental method are described. The
recorded curves for continuous impact strength of the case-hardened
samples are given in form of the dependence of a nunber of impacts
until destruction upon the energy of the single impaci. It is shown
that the most resistant steel in the case-hardened state both in the
air and in the liquid medium in the steel 20 XM3A. From a comparison
of the curves obtained when investigating in the solution and in the
air, it may be seen that in the case of all types or steel a decrease
of impaot-fatigue-strangth may be observed when investigation is
carried out in the solution. In the case of short investigations
(20-40 min.) in the liquid medium this decrease amounted to 38-42%,
in the case of tests of long duration (45-50 hours) it amounts to
53-55%. In order to detemine the influence exercined by the compo-

comparative impaot-fatigue-tests were carried out with case-hardened
samples of 12 KW2A steel in pure distilled water, in the air, and
in a solution. It is shown that the greatest decrease of impact
strength was obser7ed in the case of the test carried out in the
solution. The investigation of the destroyed sample showed that the
working surface of the sample had no oxide film an a result of a
test carried out in distilled water, in contrast to the surface
obtained by the investigation carried out in the solution. It is
assumed that, besides the phenomena of the adsorption and strutting
effect, the reduction of impact strength Is caused also by the
affect of corrosion. In the came of short experiments the effect of
corrosion is of no importance, but with an increase of the duration
of the experiment the role played by it increases steadily. The data
obtained agree well with the testa carried cALt in nature with
drilling milling cutters ( the latter developed in a liquid medium
under cyclical impact streesee). There arc ) fiVires, i table and

developed. Comparative impact-strength testt; were performed
on .11 different types of steel. It was established that the in-
crease in impact strength; produced during surface hardening
of the CDB by means of cementation, is decisively affected by
the strength of the carburized layer (CL), rather than by the
magnitude and nature of distribution of the residual and surface
stresses. It is therefore essential that sucn alloying elements

in liquid medium is given. The investigation showed that the
intred-,iction of n-Ackel and copper into the -asehardening steel
inc:reases the fatigue impact strength of steel. The fatigue
impact strength of steel increases, on account of casehardeningg
only tu a certain depth of the hardening layer. The optimum
e-epth cf the hardening layer is obtained at a ratio of 0.18-0.22
between depth cf layer and radius. In the investigation of the
oasehardened samplas for fatiguo impact strongth in liquid
medium, the impact endurance limit of the steel decreases
strongly both in continuous tests (50-55 hours) and in
shcrt-termed tests (30-40 mizrates). The new types of steel
sUggested here can be recommended for tf~e production of parts

ABSTRACTj A mothod of forming tho transmission fund-tions of extra-

existing theory of impulse control for an analysis and
synthesis of systems containing these devices. The extra-
polating devices serve for transforming the discreet data
into continuous (or continuous in places) ones. The follo-
wing is showns 1) In the investigation of the dynamics
of the control system %ith an impulse element, connected
in series, with an infinitely small reciprocal of the pulse

which forms pulses of a rectangular shape and To 1, and
by the linear (continuous) part of the extrapolating de-
vice which is also connected in series. 2) The transmis-
sion function of the linear part of the extrapolating de-
vice can be found by the application of the usual (and not
discreet) Laplace transformation. Thko tronamission function
only expresses the connection between the representation of
the input and the output quantity in the case of a certain
shape of the input action - in the case of a continuity of
the rectangular pulses with r w 1. Therefore such a func-
tion can be called a conditional transmission function.
3) On the basis of the data given here it can be stated
that the method of the conditional transmission functions
(in the sense here mentioned) is applicable when the input
action represents a continuity of impulses of any previously
known shape.

ABSTRACT: The author investigated the influence of the tempering
temperature on /the impact fatigue strength of 30KhGS steel
(0 60716 Mn, 1.20916 Cr and 0.99% Si). The impact
fa;i'Ne*,~itested on a machine, a sketch of which is
shown in Figure 11, in which a specimen with dimensions
as shown in Pigure 2 was subjected to pure impact bending
(the load was applied simultaneously at two points with
impact energies of 25 and 60 kgcm) with a frequency of
600 impacts/iain. After each impact, the sDecimen was
turned by 15 - Preliminary treatment of the specimens:
Afte machining, the specimens were quencted in oil from
880 6C, tempergd, in oil for 2 hours at 100, 200, 300, 400:
500, 600, 700 'C and, following that, cooled in air.
Three of the specimens were not tempered Sfter hardening
and a further three were annealed at 880 C for 2 hours.
Cardl/3 Comparative fracture tests were made on a "Gagarin" press
Impact Patiguello?7%Wlteel 30KhGS SOV/129-59-2-7/16
and the impact strength was determined bv means of a
pendulum impact-testing machine with an impact energy
of 30 kgm. The obtained results, graphed in Figure 3,
show that all the mechanical properties, i.e. strength,
impact strength, and impact fatigue strength increase
in the case of tempering at 200 C. For tempering
temperAtures above 200 C, the strength and yield point
values dropqbgJmpact strengtg drops sharply at tempering
temperatures from 290to 500 C. However, for a tempering
temperature of 500 C, there is an increase in the
impact strength. In contrast to this, 811e impact fatigue
strength shows a second 4- at 400 C when the impact
strength is lowest aad at 500 C the impact fatigue
strength drops sharply. In the cage of impacts of
60 kgcm specimens tempered at 400 0 withstand the largest
number of impacts, whilst in the case of impacts with
energies of 25 kgcm, the specimens tempored at 200 C
withstand the largest number of impacts,, It was found
that for this steel, the fatigue strength in the case of
Card2/3 repeated impact loading has features which are not revealed
in static tests or in single-impact bending testrn,.

ABSTRACT: The aim of the work described in this paper was to establish
the influence of the steel composition and also of the depth
and the structure of the carburized layer on the magnitude and
the character of the distribution of the residual stresses in
carburized components. The influence of allo:ying elements and
of the carbon contents on the residual stresses in carb-urizzd
and heat-treated specimens was investigated on alloy and carbon
steels with compositions as given in the table on p 42. Cyl-
ind ical specimens of 12 mm dia, 150 mm length, were investi-
gated after being carburized in-a mixture of 8% chascoal 10%
sodium carbonate and 5% barium carbonate at 910-920 C for
durations of 3-20 hours. Immedia-tely after removal from the
carburization boxes, the specimens were quencheg in oil and
quenched for a seoond time in oil from 780-800 G. gollowing
Cardl/4that, the specimens were tempered for 1 hour 4t 200 C and
SOV/129-59-6-9/15
Residual Stresses in the Hardened and the Case-liardexled Layer
cooled in air. For one of the stools the up8almeno were a~ib--
jected to intermediate tempering at 660-6030 C for a duration of
4 hours prior to the se~,ond quenching. On the ba2is of the
obtained results,. the followlag conclusions axe arrived at.
1) The. magnitude' of the resIdual stresseo axid the character of
their distribution along the i~rcss-sectioii of the quenched,
carburiz.)d specimen depends on the depth of the carbur..zed
layer as well as on the c.-hemical composition of the steel.
2) Yn increasing the depth of the carburised layer from
0.6-2.2 mm, the magnitude of the residual surface stressea
changes greatly. In the case of relatively shallow ca:Tb1ir:,.z--
ation depths, there are compression stresses at the surfa,,,e of
the specimens wh.-1.,-,h tn,:~rease- with increasing depth of -carburiz-
ation up to carburization depths of 1.2 mm. Yu:rther Increace-
of the carburization. depth 'Leads to a reduction in the comprea-

specimen siirfaces.
Card2/4
SOV/129-59-6-9/15
Residual Stresses in the Hardened and the Case-hardened Layer
3) In accordance with the changes ia the residual surface
stresses, there will also be changes in the magnitude and
the character of the stresses along the cross-section of
the carburi2gd specimens. If the depth of carburization
does not exceed 1.2 mm., there will be a continuous change
in the residual stresses aloug the aross-section.
However, if the carburization depth exceeds 2 mm, the
curve representing the distribution of the
residual stresses will show a discou'Un-mity in the
compression stresses.
4) The magnitude and the character of the residual
stresses are greatly dependent on bhe presence in the
structure of a hardened layer of exaess carbides and
of residual austenite.

PERIODICAL: Zavodskaya Laboratoriya, 1,059, Vol 25, Ur 3, PP 337-339 (USSR)
ABSTRACT: Methods have been worked out by which data on abrasion under
alternating shock-like loads as a function of composition and
structure of tile abrasion layer can be obtained. Data for the
steel types 20KhN2A, 20KhN3A, and 20N31,1A (Table) were obtained
by these methods. In principle, the tewt unit (Fig 1) is a
spring which causes the loading. An electric motor rotatev a
shaft (700 rpm). Samples in the form of coe wheels (Fig 2) were
tested; in this case the jolting effoot (in. addition to the ef-
fect of friction caused by the rotation) was conveyed by the
cogs. White electro-corundum (0.6-0.0 mm), corundum (3-5 mm),
and quartz sand, in a liquid with a composition nimilar to sea
water, were used a~; abrasion mixture. The switi~les were cemented
into hard carburizing nalt up to a la4ter thicknes3 of 1.5-1.7 rnm

The conducted tests proved that the max1mum hardne.9s
of stainless steel (without case hardening) after
quenching from 1,000-1,5000 C is not over 30 RC,
while after case hardening it jr~creases to 55-60
RC. The steel which was case hardened at 950' C
differs very little (in hardnese) from the steel
case hardened at 1,0000 C. Therefore, the authors
recommend case hardening componentsmade from
stainless steels lKhl3 ang M17 at 9500 C and
quenching them from 1,000 C. There are 2 figures;

ABSTRAM A study was done an iron-base powder metallurgy materials composed of 94
to 99% iron alloyed with nickel, copper# and graphite. Seven mixtures were made:
(1,2) graphite alone-4.0 and 3.0%; (3) graphite--1.0tp Cu-3.0%1 (4) graphite--3.0%,
Cu--3.0%; (5) graphite--1.0tv Wi--3.0%; (6) graphite-4.04, Mi-4.0t; and (7) gra-
phite-3.0%, Cu--1.5%, Ni--195%. Shrinkage and density were given as functions of
composition and compacting. Microstructures and mochanical:properties were datormin-
ad on the finished proft4ts., Before compacting, the powder mixtures were dicoxidized
and sifte4 through a-*croon. Cylindrical samples of 18 Wgbt an4 10 mm diameter

1050, 1100, and 11500C In dissociated ammonia. Cracking occurred above 10,T/CM2 so
for optimum compacting the*pressure was kept at 9-10 A'/cu2 resulting in a residual
porosity of 14-18%. The sintered dansity increased an a function of temperature and
became constant av 11006C; hmm-ver, at USOaC the macro- and w4cr*4truotures were more
uniform. Fftvite famed for sixtures A and #2, while pearlito t comenti-te develop-

compact*peralitic structure with a thin network of cementite. After homogenizing for.
2 hrs at GOOOC the cementite network dissolved. Maximum hardness was obtained after
sintering at 115010C. Nixtum 03 had the bighest hardness at 87 %, Tlj-- shriz*age

water quenched fresi $00, 8260 and 6500C and tempered for 2 hrs at 1900C. Mcrostruc-
tures and mechanical properties of the beat treated sawplos *ioved that every mix-
ture had an cpTimum.quenching temperature. No hardness differences wer* observed be-
tween 1 and A graphite. Quenching increased the beading strength, but decreased
the impact resistance. The impact resistance# compressive aid bending strength dit-
creased after the carbon content increased from 1 to 3%. It.was concluded that Cu

A13STRACT: The thormiordo emission of uranium dodeca)tarldeiias measured by a pro-
described earlier (Radiotekhnika I eloktronika v. 7P 2099. 3.9622). The sub-
:strate was a tungsten ribbon, on which.a thin layer (30 -- 50 ) of a dense sus-
wpension of U 12 powder in metal alcohol was deposited. As in the case of hoxaboride
~of rare earth motqlsp UB12 reacts with the tungsteno causing the latter to curl,
and causing mot, -,Io uranium to be depoaited on the walls of the bulb. The work
,function was determined from the measurod values of tho temporature and current
~density and is found to satisfy the equation 2.89 + 2.3 x 10-4 T. Deviations from a':
'linear dependence# towards lower values of the work function, are observed at 1500
1900 K and are Probably due to the start of noticeablo rosotion betwoen UB12 and
