TEXT: The laws are studied which govern the changes in the
carbide phase and graphitization during plastic deformation and
subsequent heating of the steels y 12 A (U12A), ~ 10 A (UlOA),
y 8A (u8A), y 7 (U7) and 60, with carbon contents of 1.~9 to
0.60/. ~'~fagnetometric and dilatometric methods were usea for the
main investigations; the changes in the average composition of
the carbide-phase region were a18o calculated. The results
indicate that the action of cold plastic deformation on the
aunt�nite is as follows. The cementite particles are crushed and
some of them decompose and break down, resulting in the formation
of free carbon aid iron which leads to increasing magnetization
cf the steel. The carbon atoms Surround the remaining cementite

particles; a possibly important factor here is the attraction of
impurity atoms to structural imperfections and the cementite/
alpha-phase boundary. Some of the carbon atoms surrounding the
cementite plates penetrate inside the crystal latt~t.ce of the
carbide, leading to a change in its Curie point. When the
deformed steel is heated, the carbon atoms acquire a ~iigh
mobility and can react with each other and with iron atoms. ,
The first leads to formation of graphite regions, this being ~
facilitated by the presence in the alloy of micropares formed
during plastic deformation. The second leads to reformation of ~P
cementite and a decrease in the magnetization of the steel.

'I~XTS The author presents the results of research work to determine the
technology and conditions of the semi-automatic CUB-shielded arc welding of low-
alloy 15KhSND grade steel of 1~+ mm thickness. The requirements of low-alloy steel
welding are determined by the "instructions for the manufacture of steel struc-
tures from low-alloy HJI-2 (NL-2) grade steel" (H 221-56 [I221-56] MPS MKhP)s
Tensile strength not less than ~+8 kg/mm2, notch toughness of tt~e we~.ding aoint
metal not less than 12 kgm/em`, hardness of-the near-seam zone not higher than
HV 275; besi~es, the notch toughness along the fusion line should not be less
than ~ kgm/em at a temperature oF -~+0�C. The composition of the 1~jKhSNL~ grade
steel is (in ~); 0.16 C, 0.55 Mn, 0.x+9 Si, 0,58 Ni, 0,8 Cr, Q,~+2 Cu, 0.04 S and

kei. In nickel o oxer purity, the slow grain growth, even at an annealing t~apera-
tore of 1200�C, was caused by the impedance of grain boon/ary migration due to impuri-
ties. The height of the grain boundary peak decreased with grain size and impurity
content. For 99.99$ nickel, two internal friction peaks occurred, one at 400.440�C ands
the other at 620-630�C. The heights of both peake decreased with a rise in annealing
temperature or grain Size. In 99.99$ nickel, a heterogeneous grain structure was re-
crystallized at 600�C, at which point the height of the peake dropped sharply. The
625�C peak height increased with a rise in internal friction heating rate. It also de-
creased monotonically as a result of maintaining the sample at 625�C far periods up to
1 hr during internal friction testing. This peak was related to secondary recrystalli-
zatian in the 99.99$ nickel since the activation energy of recryetallization was high-
er than that of grain boundary relaxation. In electron beam melted nickel an extrene
amount of background dmaping was observed in deformed samples. This damping becarce

;annealing up to 6~�C. These changes were partially caused by the redistribution o! in-~
teratitial impurities during annealing. Transaissfon electron Microscopy showed that
the density and distribution of dislocations did not change after annealing up to ~OOa
Thus in the alloys the internal friction decrease was caused by polygonization. Micro-
structures did net show any differences between pure chrc�ie~a and the alloys that
would account for the internal friction recovery. At high testing temperatures, the
internal friction increased sharply du~a to grain boundary relaxation. The rise in in-
ternal friction at high temperatures was the name for aU, of the aatals. The shift inii
initial rise of internal friction with annealing ~~ais caused by a decrease in both die-I
location density and grain boundary area. After annealing at similar temperatures,
the value of in~e real friction was highest in the alloys, due to the retardation of -)
tallization~-by alloying. In the 300-600�C temperature range, the change in Q i
was caused by polygoni$ation in Cr t 1$ Y (the recrystallization temperature of Cr-Y
above 800�C), while in pure chraaium above 600�C it was due to recrystallizatian. In-
ternal friction peaks occurred at 900eC in pure chromium at an oscillation frequency
of 2.8 cps. In Cr t 1$ Gd a similar grain boundary peak occuarred at 960-970�C at a
,fz+�quency of 2.1 cps. In Cr t 1$ Y the peak was not observed because alloying with yt
triu~a raised the peak into a higher temperature range. The temperature dependence of
the square of the frequoncy is proportional to the shear oodulus. Dsviativns Eras li- ,.~...
fnearity were observed in the same temperature range where the sharp rise in Q-D was
observed. This change in shear wdulus was caused by grain boundary relaxation and laC-

TEXT; The present paper has been read at the 9th Conference on Luminescence
Crystal i'hosphors)o The authors have studied the effect of infrared light
from kC -1g (KS-19) and VIKC-3 (IKS-3) filters) upon the light blue
luminescence of AgCl~ Luminescence was excited by the 3~6-m~ line with
the samples being cooled down to the temperature of liquid air. The light
blue luminescence was isolated through an C 3C>18 (SZS-18) filter and
recorded by an ~3~-19 M (FEU-19D~)o The voltage pulses from the photo-
multiplier was fed into an 3H 0-1 (ENO-1) cathode-ray oscilloscope. When
infrared radiation was turned on during a constant excitation by light,
a flashing and subsequent extinction of luminescence was found to take
place Turning off the infrared light i9 accompanied by a brief attenuation

of luminescence (negative flash) and by a slow increase in brightness to
its steady value. A flash of 11ght blua luminescence (length of the
flash about 1Q sec'1) can be observed when infrared light is turned on
some time after the exciting radiation has been turned off. A repeated
application of infrared light dose not lead to this effect if the intensity
of this radiation exceeds a certain limit, These first results lead to
the following conclusion: Under the action of the light exciting the
AgCI phosphor, recombination of one part of the electrons and subsequent
radiation takes place. The other part is trapped by adhesion levels (straps).
When the infrared light is turned on, the electron escape from the traps
entails a flash of the light blue luminescence. The intensity of this
flash may serve as a measure of the number of electrons stored on these
levels, if the intensity of the infrared light is sufficient to free the
adhesion levels from electrons The intensity of the light flash depends
hyperbolically on the time betwean turning-off of the exciting light and
turning-on of the infrared light. The dependence of the light flash on
the intensity of the exciting light was examined It was found that the
intensity of the flash decreases linearly with increasing intensity o:� an
ultraviolet radiation The authors ascribe this effect to the de-exciting

action of the exciting lights In the range of infrared intensities used
ir. the experiments it was found that the intensity of the ''lash during
excitation depends linearly on the intensity of the infr~.ed radiation.
In thermally treated AgCl aample~aa the authors observed c green glow
which could be quenched by infrared light (without a flash), The orange
luminescence of molten Agar layers is also extinguished by infrared light
(IKS-3 filter)q Alight flash was not observed when the infrared light
was turned ono When it was turned off, the brightness of the orange band
of Agar increased considerably faster than that of the light blue bands
of AgCl, These results prove the conclusion that different centers are
responsible for the light blue and for the green bands of Agu^1. These
results are indicative of a different luminescence mechanism of the bands
concernedo The authors thank T~ Xa~ 5~r and S~ I~ Golub for taeir interest
in this study. 4Abstracter's notes Essentially complete translation.

TEXT: The dark polarization and photopolarization of AgCI single crystals
were determined at -150oC. The current that passed through specimens de-
polarized by light was measured with an electrometer. The crystals were ~
grown by Bridgman~s method and rolled into plates of 0.3 mm thickness.
The source of light was an incandescent lamp with a water filter. As the ~
intensity of the electric field pas increased from 1 to 6 kv/cm, the de-
polarization currents of the dark and photopolarization rose linearly from
,~ 7.10-10 to �,48.90-10 a, and from N12.10-10 to ~ 67.10-10 a, reap�otively.
At lower temperatures, the total polarization is essentially determined by
the photopolarization. The highest oharge density was 40.909 ooulomb/om .
With light of high intensity the photopolarization becomes saturated. Both
kinds of polarization hyperbolically deoreaee in time (exponenta~ a ~ 0.95
