ABSTRACT: The lifetime of carriers In silicon single crystals with a resistivity from
6-103 to 4-104-ohm-cm was studied by measurements of the relaxation of photoconduct-
ing in an apparatus similar to that described by S. M. RyVkin (196,11). The samples
(whose temperature varied from 90 to 5200K) were parallelpipeds of p silicon of dimen-
sion n-10xlOxlS I ive contacts were formed by vacuum brazin VU a vapor depo-
;afg
sited ~ aluminuM,Fatrie4. TAn equilibrium generation volume of carr ors was obtained by
passing light t: i;ugh a' I cm thick silicon filter at room temperature. Under this
method of measurement, the surface is found to have a negligible effect on the volume
lifetime of cirriers. Since the concentration of.recombination conters in the samples
was found to be slight, the relaxation time constant of photoconductivity -1 is the same
as the lifetline Tn of electrons. The data for the dependence of -t,, on temperature and

injection level y at high temperatures indicate that recombination accurs through mul-
ticharged centers. The temperature dependence of the time constant in a p-type semi-
conductor (in the case of doubly charged centers calculated using an activation energy
of 0.41 ev) agrees with the results for the majority of samples. Furthermore, using
the results of J. Okada (J. Phya. Soo, Japan, 14, 11509 1959) for thedependence of -r
on y, the data indicate that the recombination level is in the lower half of the for-
bidden zone and has a donor character in agreement with known data (m recombination
levels in silicon. Finally, the activation energy E -8 , the concentration o and the

TITLE: Use of a field emission microscope for investigating a germanium surface

ABSTRACT: This paper reports a continuation of earlier work of the author (Radio-
tekhnika'i elektronika, 10, 576 (1965)) on the purification of the surface of german
field emitters. The apparatus and experimental technique are described in the
earlier paper. The germanium emitter was etched in 5HN03:2HE:4C11.3COO11 as described
by F.G.Allen (J. Phys. Chem. Solids, 19, 87, (1961)). The system was pumped down to
10-9 mm 11g and the germanium point was purified by the technique of E.C. Cooper and
E.W.Muller (Rev. Scient. Instrum., 29, 309 (1958)), Oxygen was provided by a silver
copper wire which had been oxidized in liquid air and mounted it, a side tube. The
tip of the germanium point was cut on the [110] direction. Simeral field emission

micrographs are presented and discussed. The migration rate of -~xidas on the clean
rface was found to be enhanced by an inverse field and flashing at 100
germanium su
to 1500 C. Heating to 3500 C drastically reduced the oxide migration rates and
heating to 6730 stabilized the oxide films, which could not subsequently be removed
even by heating nearly to the melting point with application of a field, Introductioi
of oxygen at 4 x 10-8 mm Hg led to rapid covering of the germanium point by oxygen
and decrease in the brightness of the image except at certain locations marking
clusters of oxides. Adsorption of oxygen took place as rapidly at liquid air temper-
ature as at room temperature. A lattice detect, marked by a chg.in of oxides on
(113), (011), .(1110), and (131) faces, was noted on one of the g(irmanium points.Before
the point wa*s cleaned the defect was marked by a dark band on the field emission
image, indicating enhanced etching; selective oxidation on the defect took place
after removal of about 100 atomic layers in the desorption field and flashing at
400-4500C. The author thanks T.A.SmGrodina for suggesting the Topic and 1,L.

Abstract : When, grown on media contcdning glucose and m1tose,
Bacillus oedematiens synthesizes an intracellular poly-
saccharide composed of low- and high-molecular doxtrins.
B. perfringens forms a similar polysaccharide only on
media with dextrins, though. not always. A synthesis of
stareli-like poly.9accharicles by pbosphorylases from ex-
tracts of B. oedemations and B. porfringens is actii"ated
by starch and naltose. The synthesis is slowest of all
when the initial culture is cultivated on media containing
Glucose. When cultivated on a modiun containint-- m1tose,

Avirulent strains of B. pestis were subjected to the activity of the radioactive
isotopes of those elements which are found in the bacterial cell itself. The B. pes-
tis E. V. 76 usually used for the production of vaccine was grown on culture media
containing radioactive phosphorus (P32) of varying activity, from 0.6 ac. /ml. to
20 pc. /ml. From the medium containing 2.5 mc. /ml. a mutation of D. pestis was
obtained different from the original strain in morphology, biochemical character-
istics and metabolic rate. This new achromogenic strain of B. pvstis E. V. 76 is
constant, its newly acquired features remaining unchanged after 15 months of
culture and passage through experimental Wmals. Its antigenic structure Is ana-
logous to that of the original strain. The stability of the changes thus induced is
also shown by the absence of any regression of these changes after culture on
selective media. References 17.

ABSTRACT: The authors point out that recent investigations
(Refs 1-8) of.the recrystallization of cold-worked metal
at high rates of lieating have enabled recrystallization

supported by adequate experimental data, In the present
work the authors (lescribe their investigation of
recrystallization kinetics under isothermal ' conditions of

ABSTRACT: On the premise that the productivity of bz.:tsic furnace
is 1.5 times lower than that of acid furnace, the
workers of Lugansk Locomotive Plan-, imeni October
Revolution (Luganskiy teplovosostroillIel I I-I.-.7y zavod imeni

Valldemirov, V. A., and Ivanov, V. I., investigated the
possibility of sulfur and phosphorus removal in the acid
electric furnace during smelting of alloyed steel. In
the beginning, after melting of the charge and after
first slag tapping, ferrous-lime slag was added, for
the decrease of phosphorus content (2.5-3 kg of dry
iron ore, and 5-6 lcg dry lime per ton or oteel). This
Card 1/2 second slag was tapped after 20-2~. min, reducing phosphorus

content by 0.005-0.01%. Upon the suggest-fon of
Topaller, M. I., addition and removal of slag was
done before complete melting of the bath, reducing
Phosphorus content by 0-005-0-015%. For tile decrease
of sulfur content new slag was added (freshly calcined
lime 8-10 kg/ton, and crushed chamotte 2-2-5 kg/ton).
After 15-20 min slag was completely removed and new
deox1dizing slag was applied (limestone, sand, and
chamotte in the amount Of 2% of metallic part of charge
in ratio 1.2;1:1). At the same time, ferromanganese
was added in order to obtain 0.115-0.20% manganese
content in steel. The steel produced at the plant
conformed to State Standards (GOST) and D3 successfully
used by plant shops. There are -1 tables.

ABSTRACTs In spite of the deleterious effects of oxygen and some
other gases on the properties of titanium it is not of-ten
that under industrial conditions this met4l is annealed
in vacuum or in a protective atmosphere, the modern
tendency being to anneal titanium in air and reduce th6l'
degree of oxygen absorption and scale formation by
reducing to minimum the time at elevated temperatures.
This is most conveniently achieved by the application
of high-frequency induction or electrical resistance
heating and the object of the investigation described in
the present paper was to study the charact.,pristic features
of -the recrystallization process taking plLaae under these
conditions as well as the effect of various factors
(annealing temperature, heating and cooling rates) on the
Cardl/4 properties of so annealed titanium. The experiments were

carried out on specimens measuring 2 x 8 x 150 mm,
cold-rolled to 60% reduction in thickness after a
preliminary vacuum annealing at 780 0C. An alternating
current (2 500 cps) was used for heating, the rate of
heatin9 achieved in this way varying between 20 and
1 000 C/sec. The temperature and time intervals of the
primary recrystallization irere determined by hardness
measurements and the beginning and the end of recrystal-
lization were pin-pointed by metallographic examination.
The jesults were compared with those obtained on identical
z-pecimens vacuum-annealed for half-an-hour at various
temperatures. It was found that when electrical resistance
heating was employed, the recrystallization range was
displaced towards higher temperatures; thus, for instance,
I-dien the rate of heating of 100 ()%;/sec was employed,
the temperatures of' the beginning ahd end of recrystal- 0

difference increased, as is shown in Figure 2, where
tn and t k are plotted against v (0C/gec). The rate
of heating had no effect on hardness (Brinell) of 2
recrystallized titanium, which never exceeded 180 kg/mm
The reduction in time, necessary for the process of
recrystallization to proceed to completion, observed in
specimens heated by the passage of electric current, 'was
attributed to the fact that under the conditions of rapid
heating, the processes of recovery and recrystallization
took place both at the same time and temperature. J~~- ~
frequency induction heatingtiwas used in the last series
of experiments, in which titanium strips (2 x 10 x 150 mm)
were annealed by passing them at a constant rate through
a loop inductor so as to attain the temperatures of
800-825 or 85o-88o Oc in 10 or 3.5 see, respectively. The
mechanical properties and the degree of oxidation of
Card3/4 specimens annealed by this method wore compared with those
of similar specimens- annealed in the furnace (10 min at

the UTS of titanium was the same, irrespective of the
method of annealing but the ductility of metal, annealed
by rapid heating, was -31ightly higher and Ats grnin size
was approximately 1.5 times smallon, in spite of higher
temperature attained, the cbgree of oxidation of the
rapidly heated apecimens was several times cower than
that of the furnace-annealed material. In addition to
these advantages, the technique of rapid annealing by
means of electrical heatUng opens wide possibilities of
me(;hanization and automation of the process of annealing
of cold-worked titanium. There are 3 figures, 1 table

TEXT: The object of the present investigation was to study
the relationship between the activation energy for creep of
a-iron and the applied stress as well as the relat'Lonship
between the activation energy for recovery of this metal and
the degree of plastic deformation. Technical purity (99.76%)
iron, preliminarily annealed in vacuum (10 hours at 7000C
followed by 50 hours at 45VC), was used in creep 'tests
carried out in vacuum (10- mm Hg) at 250 5000C under a

constant stress ranging from 10-35 kg/mm The ln ~ versus
I/T relationship, where i is the rate of creep and T -
temperature, was linear over the entire range of the applied

for steady creep (A H) is demonstrated in Fig.,2,, where
AH (kcal/g atom) is plotted against the applied stress

technical and high-purity iron (99.67 and 99.99%, respectively).
The experimental wire specimens, 0.6 and 1.5 mm in (liameter',
preliminarily annealed in vacuum (3 hours at 8000C) were
deformed plastically at room temperature to 80, 84, 94 and
98% reduction in area. The kinetics of recovery were
studied by measurements of the thermo-emf of plastically-
deformed against annealed material, which were taken immedintely
after deformation and during subsequent isothermal treatment

does not affect the limitinx (minimum) value of . It was
inferred from the results obtained that the activation energy
for recovery is a function of several states of the crystal
lattice, which vary not only with the degree of preliminary
deformation but also with the degree of recovery attained~
The dependence of the activation energy on the degree of
recovery can be attributed to the following factors:

1) the presence in a deformed metal of volumes with different
density of defects of various types;
2) variation of the density and distribution of defects during
isothermal treatment;
3) different stability of different types of defects;
4) dependence of the activation energy for recovery on the
nature of the defects and their density in elemental volumes
in which they migrate. i

TITLE: A study of the grain growth in highly pure m-iron
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 138, no. 2, 1961, 338-341
TEXT: The iron investigated contained the following impurities : 0.001 ~fb 0,
0.001 % C, 0.002 % S, less than 0.002 % N and traces of Cu, Ni, and Si.
Iron rods of 7.7 mm diameter were subjected to a preliminary treatment
during which they were cold formed and, subsequently, subjected to a
recrystallization annealing; the resulting grain size diameter was less
than 0.2 mm. Grain growth was studied at electric heating and a mean rate
of 200 degrees/sec. In the range of from 700 to 9000C, the rate of heating
was reduced from 300 to 150 degrees/sec. After heating to a pre-determined
temperature, the specimens were chilled in water, the interval between the
end of heating and dipping of the sample into water being less than 0.02
seconds. The temperature conditions of heating were registered with a
Cr-Al thermocouple, which was fixed in the middle of the sample, by means
of a loop oscilloscope and a ballistic galvanometer. The results of

measurement are graphically represented in Fig. 1. When heating at
constant rate a, the rate of shifting of the grain boundaries G can be
determined from the equation G - 2-adD/dt, where D = f(t) is the mean grain
2
diameter. If a is not constant, D =,y(T) must always be determined (T
denotes the time). The lower part of Fig. 1 shows the temperature t as a
function of time. The curve t = Q(T) is determined from the oscillograms.
The curve D = V(,T) is constructed, as shown in Fig. 1, by means of the
experimentally determined curve D = f(t). (Fig. 16). According to the
above equation, the values G = 128; 188; 210; 230; 300 and 354010- 50M/sec
are graphically obtained from this curve at temperatures of 735, 765, 790,
810, 865 and 8900C. In another experimental series, the specimens with
700 degrees/sec were heated to 610 t5oC and kept at this temperature for a
varying length of time according to the individual specimen, e.g. for 0,
0-4, 1.0, 2.25, 3.0, 125, 275, 660, 900 and 1800 seconds. The respective
,arain diameters were: 43, 63, 87, 128, 141, 175, 194, 205, 210 and
240-10-4 CM. The mean linear shifting rate of the grain bo-andaries was in
the given periods of time 250, 200, 164, 87, 1.31, 0.63, 0.20, 0.10 and

0-17-10-- 5 cm/sec. The slowing down of the shifting rates of the grain
boundaries is explained by the reduction of the radius of 3urvature of the
grains and the increasing concentration of impurities at tae grains.
Owing to the high purity of iron, this state occurs only with very large
grains. Prom the discussion of the results the authors conclude that the
mechanism for the grain growth as suggested by Mott (Proc. Phys. Soc.,
60, 391, (1948)) is very probable. Accordingly, the grain, when growing,
melts at its boundaries and solidifies again with the boundary being
shifted in outward direction, The authors, experimental data can be
easily described by Feltham's equation (J. Inst. Metals, 85, (2) 95, (1957);

The results of the second experimental series are in good agreement with
(2). Herefrom, 25.3 koal/gram-atom is obtained as activation energy for
the grain growth. In a preliminary study (Ref. 20 Izv. AN SSSR,
Metallurgiya i toplivo, No. 2, (1960)), basing on the hypothesis on the
activatiQn energy of various processes in solids, the authors obtained
theoretically an activation energy of 22.2 kcal/gram-atom. Finally, the
fact is discussed that in the case 'of lead and iron AH and q are almost
equally high (s e'e Ref. 20). This is brought into relation ivith the
melting and re-solidification of the grain boundaries. V. P. Fedotov
supplied the pure iron for this study. There are 3 figures and 24-

TEXT; Earlier investigations showed that with increasing
rate of heating the rate of recrystallization of.cold-worked Fe
and Ti increased and the activation energy decreased. In -the
present investigation the effect of the rate of heating, during
aniiealing of cold-worked commercial grade Ti, on the kinetics of
recrystallization, the grain size of the recrystallized materie1l-------'_
and the critical degree of deformation, was studied. The
experiments were carried out on 1.5 x 6 x 150 mm test pieces
which, after the last intermediate annealing, had been plastically
deformed to 9.8, 21, 40 and 60% reduction. Specimens were heated

by passing mains A.C. at rates of heating ranging from-10 to
1000 *C/sec. Hardness of the central part of the test piece 'was
measured, the grain size determined and, when necessary, X-ray
diffractioa analysis carried out. With isothermal annealing in
which the effect of the degree of preliminary deformation, c, and
the rate of heating on To and Tj was studied (where 'ro and
denote, respectively, annealing times required to start and
com~plete the recrystallization process), it was found that with
increasing E both To and Tj decreased at a gradually
diminishing rate, becoming negligible at E -.;,40%. Increasing
the rate at which the test pieces were brought up to the
annealing temperature also caused a decrease in both T 2 and Tl
for all values of E, typical results obtained at 900 C being
as follows. For specimens deformed to 9.8% reduction and heated
at a rate of 30 and 300 *C/sec, To was 15 and 8 sec respectively,
the corresponding values of Tj being 70 and 50 SOO;* for
specimens deformed to 40% reduction To was 3 see at 30 'C/sec
and 0.6 sec at 300 *C/sec, the corresponding valuesi of Tj
being 5 and 2 see. In the non-isothermal annealing, each test

piece was heated through a range of temperatures to determine the
effect of various factors on the temperature of the beginning and
end of recrystallization of T! (tH and tK, respectively) and it
was found that, irrespective of the degree of preliminary
deformation, both the beginning (tH) and the end (t:.K) of Ti
recrystallization increased by 70-150 *C on accelerating the
heating rate, the rate'of increase in each case diminishing as the
heating rate increased. At any given heating rate both tH and tK
increased with increasing C; the rate of this increase also
became insignificant at C > 400/o. Typical results tire reproduced
in Fig,3, where tH and ty, (*C) are plotted against C (%), graphs

of experiments showed that the detrimental effect of preliminary
deformation on the grain size of recrystallized Ti can be
considerably reduced by increasing the rate of heating, thus
obtaininj finely-crystalline and more uniform structure. In Fig.'5

the grain size of annealed Ti is plotted against the degree of
preliminary deformation (e, %) and various curves relating to the
following annealing conditions in furnace and by passing electric
current are also discussed: I and 2 - heating in a furnace to
840 or 730 *C respectively, holding at the temperature for 30 min,
cooling in air; 3 - heating by passage of electric current to,,tF.
at a rate of 10 OC/sec, cooling in air; 4 and 5 - heating by
passage of electric current to tj~ at a rate of 250 OC/sec,
cooling in air (curve 4) or in water (curve 5); (the broken
horizontal line represents the initial grain size). It was found
that the critical degree of deformation, EK, can be slightly
shifted towards lower values by increasing the heating rate, but
only if the duration of the treatment is relatively short
(2 - 5 min); in the case of non-uniformly deformed. articles,

as described in earlier work (Ref.,l), For hardness measurements,
X-ray and metallographic investigation, the parts of the specimen
close to the thermocouple position were used. Recrystallization
isotherms, i.,e. plots of recrystallized initial grain volumes

tion falls with rising annealing temperature, The logarithm of
time to reach a given degree of recrystallization was found
(Fig,,2) to be linearly related to reciprocal of absolute
temperature, enabling the activation energy of the process to be
calculated. It is shown in Fig.3 in relation to degree of
recrYstallization- The true (curves 1 and 3) and average (curves
2 and 4) rates of recrystallization are shown in Fig,4 as
functions of degree of recrystallization (curves 1, 2 after
