On the Problem of the Influence of the Electric SOV/'/7-58-6-17/37
Field in a Cathode on Its Electron Emission
the field (and of the current) is not essential in this
process. A corresponding generalization of the reoults from
reference 2 is also carried out with respect to the pas:,a.,c
of current through electron tubes. Tile problem of the
emission of a gas not in equiLibrium can be ge.icralized as
follows: If a current I passes through a semicondutor or
a metallic cathode two phenomena necessarily occur in tile
cathode: The heat effect (determined by I R) and tile effect
of the electric field (determined by IR). These effects may
occur in three principal quantitative ratios: 1) The heat
effect considerably exceeds the "field" effect, 2) Both
effects are about equal, 3) The " field" effect consider--bly
predominates above the heat effect. If the cathode is driven
by pulses the conditions for a relative increase of the field
effect are more favorable. There are 3"refere ces, 3 of
which are Soviet.

ABSTRACT: Secondary metals occupy a significant position in the total con-
sumption of nonferrous metals. Thus, secondary Cu, Al, and Zn
constitute >113 of the total of these metals used in this country. It
is therefore necessary to adhere strictly to the rules for collection
and storage established by a special standard according to which
scrap of each metal or alloy must be kept separately. With this
purpose, all machine tools are provided with trays and other equip-
ment for scrap collection. There.'jis a complex of measures with
the objective of assuring and stimulating careful collectionjAnd
proper storage, as well as delivery of nonferrous scrap anii rejects.

various establishments to carry out measures to improve collection and storage.
Higher prices are paid for scrap delivered in unmixed form and with a rating
sheet than for mixed and contaminated scrap. Thus, the price for clean Cu
swarf is 89% higher than for dirty, unrated swarf. The corresponding price dif-
ferential for brass swarf is 447o, for Sn-bronze 3676, and for Al swarf 6176. Care-
ful preparation of the chip is needed before remelting.

TITLE: The synthesis of correcting devices of linear systems for a given
accuracy at a fixed instant of time
SOURCE: AN SSSR. Izvestiya. Tekbnicheskaya kibernetika, no. 4. 1965, 119-125
TOPIC TAGS: linear automatic control s stem, linear system, linear control system,
control system stability
ABSTRACT: In the majority of cases the structure of the system under design and
the distribution of its known loops as well as of the correcting onea (the para-
meters of which have to be determined) are given in advance. The authors show that
for systems the accuracy of which is essential only at fixed instants of time,
stationary circuits may be used as correcting loops securing the agreement of the
characteristics of the projected uystem with their optimum values. The notion of
equivalent systems having equal accuracies at a fixed instant of time is introduced
and the properties of such equivalent systems are studied. Formulas for the
determination of the transfer functions of stationary correcting loops are also
derived. Orig, arte has: 33 formulas and 3 figures.

of boron is observed when heating for quenchinf, is carried
out to temperatures of 1075-1150 C. At lower or higher
quenchin g temperatures, the carbide network formation
occurs in the same way as in steel without boron
addition. The influence of boron is the greater the
lower the carbon content of the steel: In 0.06% C steel
boron practically completely prevents formation of
carbides that can be seen under th4e optical microscope;
at a carbon content of 0.14%, t'112 influence of boron
becomes negligible. From the TaUle i-:; can be seen -that

The results of the investigation obtain,~d
V. I. Arkharov's theory of prefe~:,~atial diE;t--;bUt-1On of
impurities in the grain boundaries as result of the
tendency of the alloy to lower 1-ts exces-- surface enarg
(Ref 4 and others). AccordinL, ~.v V. I. Aricharov (Ref U,
the mechanism of the influence of boron or, the ability
of structural steels to be temnered consists in the
Card 3/5 fact that the enrichment of intercrystalline boundaries
MV/126-7-2-3P/39
The Influence of Boron on the hature of Carbide Separation
in Austenitic Steels During Tempering
with boron leads to a decreu--;e in the distortion of the
crystal lattice as a result of which the work for the
formation of critical nucleation of the separatinC
phase increases. This explonation is applicable
apparently also to the effect shown in this viork.
The decrease in diffusion rate in the grain boundary
zone (Ref 6), in this case of carbon under the influence
of boron, -md the ejection of carbon fron the boundary
zones can also be factors influeneinC the retardation of
carbide particle formation. Lot us note that boron
retards the separation of exce-1-- -phases f:,o;2 austeni"U.-
of different composition (carbon and alloy steels ?
austenitic stcel). The surface activit-,- of boron is apparent
in nickel base alloys (Ref 7) and in icon (Ref 6). JUnoing
the number of factors influencinG intercrystalline
adsorption (Ref 9), in the case of boron the determining
factor is a geometrical one. The atomic radius of boron
is smaller than the radius of atoms forming a
Card 4/5 substitional solid solution in the alloys listed, but is

The Influence of Boron on the Nature of Carbide Separation

greater than the radius of atoms going into solution
interstitially. This is hound to lead to a Ereater
solubility of boron in distorted orain boundary zones
as compared with the solubility ir. the grain bodies.
It appears that in the construction of intercrystalline
boundaries boron atoms play a smaller role as "structure
material" than metallic atoms.

after that were c_-~-,led in air. From thus-treated strips
(210- --- 2200 mm), specimens fcr mechanical tests were

investigation contained 0.09 % C; 17-7 % Crg 10.9 % Nit 1.2 % Mn,
0.2 % Big 0.022 % Po 0-014 % S. These samples were quenched in
water from 10500 and tampered at 600; 650; 700 and 7500 for two
hours. The specimens were blanched with a solution of bromine in
methanol with only the metallic bass having been dissobod. In this
treatment the carbides rose above the surface of the ground
section and maintained the position they occupied already in the
steel. The collodion prints with the "captured" particles were
evamined in an electron microscope for stereophotographs. Carbide
particles at the grain boundaries and a relief of the blanched
surface were investigated. The character of the carbide

two grainst there existq howeverp differences between the
individual boundaries, Dispersity decreases with decreasing temps
ture of tempering. In all cases the plane of the increase of the
particles agrees with the boundary between the grains. At
tempering temperatures of 600 and 6500 carbide precipitates were
observed not only at the boundaries but also within the grains.
The intergranularg much more dispersed particles are found where
the uniform orientation of the blanching patterns is disturbed.
The carbide particles had'the shape of two-dimensional dendrites
(20W4 cm to 7,1e4 cm long, maximum thickness of the order of
1076 cm). The point electron diffraction patterns which belong to
the lattice of the cubic carbide (Cr,F9)23C6 were used for
determining the orystallographical planes and the directione of
particle growth. The branches of different orders of the
dondritee of carbide belong, as a rulev to different planes for

TEXT: The work described in this paper was devoted to studying
the influence of small additions of various elements on the
character of rejection of carbides during tempering of austenitic
stainless steels and the stability of such steels against inter-
crystallite corrosion. For the investigation a nitrogen-
containing, chromium-manganese-nickel steel was chosen (0.09-

The additions used for preventing rejection of carbides at the grain
boundaries and for preventing the tendency to inter-crystallite
corrosion can be subdivided into the following two groups:

admixtures which combine with carbon to form strong carbides;
admixtures which reduce the excess energy of the inter-crystallite
transient zone. As elements of the first group the authors chose
Mo, Nb and Ta; as elements of the second group they chose Be, Cal
Ag, Ce and B. Grade A electrical ironv nitrided ferro-chromium,
low-carbon ferro-chromium and metallic manganese were chosen as
charge materials for the laboratory high-pressure furnace, whilst
carbide-forming elements were introduced into the steel in
quantities which are required for carbide formation. Other
additions were introduced in quantities between thousandths and a
tenth of one percent. The ingots were machined off to a depth of
3-5 mm and forged into rods from which specimens were cut out.
Specimens for micro investigations were heated in a salt bath to
temperatures between 950 and 1250 OC in steps of 50 OC for one hour
and then uenched in water. The tempering was by heating for two
hours at Z50 OC. In some cases additional tempering for 15 minutes
and two hours was carried out at 700 and 750 OC. The quenching

the boundaries was determined metallographieally. Following that,
specimens were treated according to this regime and used for
determining 'the tendency to inter-crystallite corrosion, which
was determined after boiling of the specimens in astandard
solution and inspecting the crack formation caused by subsequent
bending,and by measuring the increase in electrical resistance.
In some of the steels the carbide phase was separated
electrolytically in & saturated solution of sodium chloride which
was acidified by hydrochloric acid. The thus produced
precipitates were subjected to X-ray Analysis using cobalt
radiation. Six microstructure photographs of various steels
(without and with additions) after quenching and tempering at
650 OC for a duration of 2 hours are reproduced on p 21. The
results of Investigations of the tendency to develop inter-
crystallite corrosion after quenching and tempering at 650 OC are
entered In a Table on p 23 for steels from 26 heats. On the basis
of the obtained results the following conclusions are arrived at.

steels can be prevented by reducing the carbon content from 0.09-
0.12% to 0.04% and also by introducing molybdenum, niobium and
tantalum. The resistance to inter-crystallite corrosion during
tests in a standard solution is maintained In low carbon steel and
also in steel containing tantalum to an extent of 20 times the
carbon content. Addition of tungsten and also an increase in the
niobium content in excess of 10 times the carbon content leads to
ferrite formation. Berrylium accelerates the rejection of carbides
during tempering of hardened steel, whilst calcium, silver and
cerium do not influence this process within the range of
investigated quantities. Boron (0-003-0-10%) prevents the formation
of a carbide network in the case of tempering at 650 OC, but assists
such formation at more elevated temperatures. The influence of
boron depends on the quenching -temperature and on the carbon
content of the steel.

An Investigation was carried out upon the boron distribution In Fe-b
and stainless steel. A liquld ermulsion A-2 was deposited by dipping upon micro-
sections, by the method worked out at the NIKFI. The specl ens were irradiated
by thermal neutrons; a Po-Be source with power of -3 * 10 neutrons/sec was
used. A nonuniform distribiition of B was noted in the Fe-B; In 3tainleSs steel
no zones of intorcrystal lite F3 absorption were discovered, apparently because of
their small thickness and Inaufficlent resolvIng power of' the ratilographic miethod.

TEXT: In this letter to the editor the author reportshis study
by the tracer method of the influence of boron in stainless
austenitic steels on the diffusion coefficient of iron. For
measuring the activity of the integral residue he used the method
of Borisov et al (Ref. 6) which has advantages over that of Fisher.
Two steels, types IKhl8N9 and Khl7N4G8A, were used, respective
percentage compositions being OeO8, 0.08 C; 18.0. 17.5 Cri
9-3, 3.8 Ni; 1.2, 7.6 Mnl 0, 0.20 N; 0-20, 0-50 Si;
0-015, 0.012 P; 0.018, 0-013 S. One heat of the first steel
contained in addition 0-000510' B and one 0-00514' B; and of the
second 0.005 and 0.009% B. After annealing and forging
12 x 12 x 10 mm specimens were hardened to give a grain size of
19-22 and 25-26 IL, respectively, and a 2-6 4 thick layer of

Figs. I and 2 show for lKhl8N9 and Khl7N4G8A steel, respect-
ively, plots of the ratio of specimen radioactivity after
removal of a layer of thickness y to its initial value
against y/2b , where b is the average grain size. Calculated
values of the diffusion coefficient and other diffusion
parameters are shown in Table 2, values calculated by Fisher's
method being shown in Table 3. For each steel the first
addition of boron produced a considerable influence, the next
comparatively little. The author has previously observed with
V.I. Syreyshchikova (Ref 11) that boron effects carbide-phase
precipitation kinetics; this is probably due to its offect on
diffusion. There are 3 tables and 11 references: 9 Soviet and

effects of boron are due to two sets of olopo3lng factors-

by reducing boundary diffusion, delaying decompcsition,
2) those increasing the degree of supersaturation of the solid

TITLE, Influence of Small Boron Additions on the Low Tempers-
ture Impact Strength of Austenitic Steel
PERIODICAL: Fizika metallov i metallovedeniye, 1961, Vol.11, No.4,
PP. 564-567
TEXT. Decomposition of the saturated solid solution at the
grain boundaries of austenitic xtainless steel does not lead to a
drop in plasticity at normal temperatures but it leads to brittle
fracture at sub-zero temperatures. Small additions of boron have
a great influence on the process of decomposition of solid
solutions in austenitic steels and.- therefore, they should also
influence the process of impact fratture at low temperatures- The
inves-tigations were made on Cr-Ni steel containing 0,08% C,
18.0% Cr, 9.3% Ni, 1,2% Mn, 0.2% Si; 0.015% P and 0.018% S_
0,0005 and 0.005% boron were introduced in the second and third
ingots and,from the forged rods,specimens 10 x 10 x 55 mm were cut
out. The heat treatment consisted of quenching from 950. 1100 and
1200'C followed by tempering in the range 600 to 750'C. After

heat treatment a V-shaped notch with a depth of 2 mm and an angle
of 6' was cut on one side of the specimens and these were then
soaked in liquid nitrogen and tested on an impact test machine
having an impact load of 18 kgm~ On a part of the specimens the
magnetic induction after 20 min holding in liquid nitrogen was
measured prior to making the notch. The results show that the
impact strength of austenitic chromium nickel steel,aftei two
hours tempering,le sharply reduced at the liquid nitrogen tempera-
ture. The steel is prone to brittle fracture, which appears to be
intercrystalline, Introduction of small quantities of boron
brings about an Increase in the impact strength from 1.6-4.5 to
6.8-12.0 kgm/cm2 and this favourable influence is sustained for all
the Investigated quenching and tempering temperatures. An
increase of the tempering duration to 100 and 500 hours will lead
to embrittlement of the boron containing steels but the impact
strength will still be somewhat higher than it is for steel of the
same composition without boron. 2Graphs, Fig.3, were also plotted
of the impact strength, ak kgm/cm , as a function of the
induction,.B, Gauss. it can be seen that with increasing
induction, I.,e., with increasing content of the magnetic phase in

the specimen there in indeed a decrease in the impact strength.
However, the measured induction, determined by the total quantity
~of the a-phase, is not an unequivocal function of the impact
strength. The plot,'Pig.3a, applies to steel without boron, the
plot 6 applies to steel with 0.0005% boron, the plot 6 applies, to
steel with 0.005% boron. Heat treatment regimes were as follows
(see symbols in the figure): 1 - 6000C, 2 hours; 2 - 6000C, 100 hours;
3 - 6oo*C, 500 hours; 4 - 650*C, 2 hours; 5 - 650*C, 100 bours.;
;6 - 6500C, 500 hours; 7 - 7000C, 2 hours; 8 - 7500C, 2 hours.
In boron-containing steels small particles of the cold britttle
ferrite ifill be p?resent instead of large branchings of this ferrite.
~However, long duration tempering leads to an increase in the
size of these particles and thus to a decrease in impact strength.

TEXTs The influence of grain size and the properties of
,grains of varying dimensions in forgings of steel 3A612 K
AE1612K), with respect to refractoriness and nature of cracks at
650 and 700 OC was studied. The chemical composition of this
7steel (in-1h) in as follows: 0,-09 C; 0.34 Si; 1*19 Mn;

300 mm diameter. The forging was cut into longitudinal templets
of 20 mm thickness. Specimen billets were cut from peripheral
.portions of the latter, in order to exclude the influence of

,defects in the central zone. The templets were soaked at 1200 OC
for 2 hours and quenched. They were then ground on two opposite
sides and etched in order to expose the nature and size
,distribution of the grains. Etching was carried out at room
temperature in a solution consisting of a mixture of 20 weight
parts of hydrochloric, 10 parts of nitric acid, and one part of
potassium dichromate. The average grain size on the surface of
~billets of 20 x 20 mm cross section was determined by measuring
the diameter of 200 grains. Selected billets were tempered in
three stagess at 850 OC for 10 hours; at 700 OC for 20 houral
and at 65o OC for 30 hours. For the purpose of testing for
refractoriness, specimens of 10 mm diameter and 100 mm working
.length were cut from the billets. The tests were carried out at
700 OC at loads of 22 and 18 kg/mm2, and at 650 OC at loads of
,30 and 26 kg/mm2. Four specimens with various grain characteria
tics were tested for each load. The surfaces of the specimens
after failure and their fractures were studied both visually and
with the aid of a 'jinocular microscope. Sections for
metallographic study were made in the axial plane of the specimens.

These were polished electrolytically and etched in a sulphuric-
phosphoric-chromic electrolyte. It was found that creep occurs
under the above conditions both by viscous flow along inter-
crystalline boundaries and by slip within the grains. During
deformation, internal cracks develop along intercrystalline
boundaries in the specimens in a direction perpendicular to the
applied load. Large grains lying in the path of cracks so an to
oppose their propagation perpendicular to the specimen axis,
temporarily retard their spreading. No strengthening occurst
however, since failure develops further due to the formation of
intercrystalline cracks in other places. The large grainal
having stopped propagation of the cracks, are stress-relieved by
slip, probably after they have rotated somewhat into a more
favourable position. Vacancies accumulate along the slip planes,
cracks form and cleavage occurs, Under the conditions
investigated, failure occurs along the most closely packed
planes of the type (111). The nature of failure (intra- or
inter-crystalline) is determined 'essentially by the grain size
in the specimen cross-section. An the grain size increases, the

development of intercrystalline cracks becomes more difficult
and the destruction acquires an intracrystalline chaiacter.
So long an the grain size is small as compared with the diameter
of the specimen, the stability of the latter does not decrease.
In specimens, the cross section of which contain large grains
(3-5 mm) comparable with the diameter of the specimen, cleavage
At: in the large grains drastically weakens the cross section, an a
result of which the ape'cimen fails quite rapidly. Regions
containing small, as well as large, grains exhibit different
plastic properties, owing to localized predomination of different
mechanisms of deformation. These result in the appearance of
deflecting loads at the boundaries between these regions, which
decrease the stability, There are 4 figures and 2 tables*

hardening and ageing, possesses properties which are high for
austenitic class steels. Electron microscopy and electron

period a = 3.59 A- Apparently, the phase represents a solid
solution based on intermetallic compound N13AI. The phase -
Ni3(A(,Ti) with a face centred cubic lattice (referred to as a'-
phase in Soviet literature) was observed in nickel baapd alloys..
The chemical composition of the phase could not be-established
accurately. It contained mainly Ni, Ael Ti and small quantities
of Fe and Cr but no Co or W. On increasing the time of retention
under load to a few thousand hours, the phase in enriched in
titanium, whereupon the ratio of atomic concentrations of

352-356
TEXT: The authors have previously shown that in type 3V1612K
(E1612K) complex-alloyed heat-resisting steel the development of
inter-crystallite cracks during high-temperature deformation is
hindered and the fracture acculires an intra-granular character.
The aim of the present work was to study the creep mechanism of
this steel by investigating the intra-crystallite cleavage planes
and grains in the axial part or the specimens after fracture.
Fracture temperatures were 650 and 700 *C. Fractures wore studied
by back-reflection X-ray and microscopic methods. The results
showed that with comparatively brief tests At 650 *C individual
large grains fracture along slip planes (like single crystals).
The plane of easiest slip is the ~1111- plane of the austenite
lattice. With increasing test tiw~ and temperature the importance

-,of inter-granular flow increases and elastic bending of individual
cryntallites can occur. The relaxation of stress in these
cryatallites occurs through their breakdown into aub-grains, the
extent of fragmentation increasing with increasing proximity of
the given grain to the fracture zone. It appears that insufficient
importance has previously been attributed to fragmentation, as a
particular case of polygonization, in creep; this process needs
further study. The mechanism of the intra-crystallite fracture of
the grain undergoing fr.-igmentation has not been explained: the
intra-crystallite crack may successively 'Jump' from one sub-grain
to the next, following changes in the orientation of the crystallo-
graphic plane; it is not impossible, however, that the intra-
crystallite crack proceeds along sub-grain boundaries.

ABSTRACT: The process of failure under creep was previously Investigated for nonferrous
metals, but only a few analyses have been made of heterogeneous alloys. This paper des-
cribes the Investigation of the strengthening phase of a complex austenite steel alloy and
studies the plastic deformation and failure of this steel under creep conditions. Ile
influence of grain size on beat resistance was also investigated. The testing procedure
was carried out on an IP-4M machine. Ingots of2. 1 tons were fastened to rods 300 mm. in
diameter. :rhey were then hardened and tempered (860C for 10 hours, 700C for 20 hours$
and 650C for 30 hours). High-tomperature samples were cut from blanits with

is reportedo The Khl7N4G8A steel has 2- 2. 5 times less Ni and a considerably
higher strength than the stainless steolo The cavitation resistance was tested on
an impact-erosion outfit in which specimens fastened to a rotating disk cut &
water jet in the cavitation zone (see Zavodakaya laboratoriya, 1954. no. 6).

After 8 hro of testing, the stainless steef was found to have serious cavitation
damage with pits up to 4-mm deep; the Khl7N4G8A steel developed cavitation pits
only after 26 hra. Sand-wear resistance was tested in a centrifugal-jet bowl
device where other steals (2x 13, 4x 13, St 35, Khl5N9Yu. 30KhGSA) were also
simultaneously tooted. ZKhl3. 4Khl3, and Khl7N4GBA proved to be the most
wear-resistant, and 30KhGSA the least resistant. Further wear-resistance tests
included the 330-hr sand-water operation of an R015GM84 hydraulic turbine in
whose guide case 4 blades were made from stainless steel and 6 blades from
Khl7N4G8A steel: the wear resistance of the latter steel proved to be 1. Z-1. 4
times as high as that of the stainless steel. Orig. art. has: 5 figures and
