TRANSLATION: Be atoms collect into monatomic layers parallel to the crystallographic
planes of the (1001 matrix in the initiall hardening stages of Cu-Be (150-2000C) and
Ni-Be (400-4500C) (Guinier-Preston zones). When the Guinier-Preston zones combine
with the surrounding matrix, a mixing of atoms occurs in the matrix which..can be re-
presented as an elastic shift in the [3_103.planes in the [1101 direction. These shifts-
produce I'monoclinic" changes in the initial cubic lattice. A metastable phase occurs
.in the alloys when the time lag increases or the hardening temperature rises to 3000C
(for Cu-Be) and 5000C (for Ni-Be) due to an extension of the Guinier-Preston zone. The
sti7u~qtural relationship between the metastable phase and the solid solution is similar
io_.thatbetween ordered and unordered phases in the ordering of an AuCu alloy. The -N

!1motoclinic" changes in the matrix with the aging of Ni-Be and Cu-Be alloys are do,-
to the character of the stress state in submicrovolumes of the alloy and to the ani-

(stresses) with the aging of Ni-Be and Cu-Be alloys do not considerable increase the
hardness. The hardness increases only at the stage at which these stresses begin a
turn in the blocks of the matrix solid solution. 30 references. I. Tulupova.

1 kBSTRACT: In the investigation of the nature of the chnages
occurring in the crystal structure of the matrix, Guinier-Preston
zones appeared at the initial stage of aging Cu-Be and Ni-Be
alloys. After a five-hour tempering period at 200C single cry-
stals of Cu-2% Be specimens were submitted to X-ray analysis.
Length.and arrangement of diffusion rods along the planes and the
region of anomalous scattering were investigated. Some rods were
not centrosymmetrical. Submicroscopic berillium-depleted or en-
riched regions were identified. The period of the Be-depletion of

showed an excess of 0.5 to 1% over the mean period. At a later
stap of aging, the dislocation of atomic planes Lioij towards
U011by means of 'r causes the transformation of the cubic lattice
into a "monoolinic" lattice. The value of the dislocation is equal
i to a minimum of �50 which corresponds to r- 0.1. In aging Al-Cu
specimens Guinier-Preston zones are also identified. However, mono-:

TITLE: Comparison of X-ray and electron-diffractlon data on
the size of crystal blocks in deformed stainless

PERIODICAL: Fizika metallov i metallovedeniye, v.14, no.1, 1962,
85-91
TEXT: In X-ray diffraction determinations of the size of
crystal blocks with the aid of analysis of the width or form of
interference lines the size referred to is that of "regions of
coherent L;catterlngff. The question arises as to whether this
characterises a dimension of the crystal structuxle or is associated
with an optical effect. To solve this problem the authors have
compared X-ray results with those of electron microdiffraction from
thin foils of the test samples, simultaneous electron-microscopic
investigation of these foils being carried out. The samples
studied were of an 18-8 type stainless steel and pure nickel,
subjecte*d to cold-rolling with 96% reduction combined with heat
treatment and, where appropriate, electrolytic thinning. Some

electron micros-copic pictures (generally at 15000 magnification)
were also obtained. The authors conclude that, allowing for
svstematic errors, the block-size determinations by electron-
and X-ray diffraction give practically the same values.. The
greatest difference is with nickel, probably because the foil
thickness could not be determined with sufficient accuracy. Thus,
for deformed stainless steel and pure nickel the dimensions of
coherent-scattering regions found from measurements of X-ray
interference-line width determination correspond to dimensions of
real crystal blocks having a relatively correct internal structure
and disorientated relative to each other.

TITLE- Study of the changes in crystal structure of nickel-
beryllium alloys in the early stages of ageing
PERIODICAL: Kristallograf iya, 1961, voi. 6, No. 4, PP - 560-567 + 3 Plates
TEXT: Single crystals of Ni-Be alloys containing 2.2% Be were
quenc~hed from 11000C and aged at 425 or 5000C. The change in
hardness (Rockwell B) with the total soaking time during tempering
(in minutes and hours) is shown in Fig.l. The alloys were
studied by X-ray analysis to elucidate the changes in structure.
In the early stages of ageing (30 min to 2 hours at 4259C) the
formation of Guinier-Preston zones considerably enriched in
beryllium occurs. They are in a plate-form of 1 to 2 atomic layers
thick and parallel to the (100) planes in the matrix. At the same
time all the solid solution is less-rich in beryllium and
approaches to the equilibrium state. The depleted matrix divides
Into separate blocks which at first have different orientations one
from another. The blocks are elastically distorted. There are
cracks with thickness of the order of 20 to 30 A in the matrix

along the (110) planes. At 500*C, the G.P. zones increase in size,
regions with structure close to P phase appear and orientated
rotation of the blocks occurs around one axis of the CILOO] type.
This rotation reaches 8 to 100 after 32 hours at 5000C. The high
hardness values of aged Ni-Be alloys is connected not with elastic
distortion in the matrix but, in the main, with the division of the
matrix into blocks and with their rotation relative to one another.
All the observed changes result from the large difference in
atomic volumes of the matrix and the precipitating phase (NiBe)
which reaches 20%. There are 10 figures and 22 references.

been proposed (Refs. 3; 7), When the precipitate of the
hexagonal q-phase Ni 3Ti first appears, the regions of bcth
types became tetragonal with the above axial ratios, The
c-axes of all the regions were in the same direction so that
the initial monocrystal as a whole appeared to be tetragonal,

22 different concentrations were investigated at temperqtu-
res to 2420. The alloys with a lead concentration up to
33.67% have (at various temperature ranges for various con-
centrations) a positive temperature coefficient at a value
of ;,Lless than that of pure bismuth. These phenomena are
explained by the presence of a solid solution of lead in
the bismuth, and obviously, by the presence of an o,% phase.
The dependence of N on the temperature differs from the
dependence of ~C on the temperature, this being explained
by the heat transfer not only the electrons, but also by
the lattice. Assuming that for the electronic portion of
the conduction the Wiedemann-Franz law is valid, the au-
thors have subdivided the obtained values of ;~ into A ell
vhich in pure metals diminishes, and increases in alloys,

ture. However, this separation leads to the conclusions
that A lat predominates over A ell and consequently

doubt is expressed concerning the applicability of the
Wiedemann-Franz law for this system. The experimental
values of are in good agreement with the equation
>-%IC - A � B/T, where A and B are constants, C is the
atomic heat capacity, T the absolute temperature. C was
measured by the method of cooling in a Torovskiy-Bartenev
type setup. A slow increase in C of lead and bismuth with
increasing temperature was obtained. The isotherm of C
has a minimum at 4.82% and a maximum at 65.70~ lead.
This can be explained by the influence of the V~, phase for
small concentrations of lead and of the P phase for large
concentrations of lead (C of the ck, phase is smaller than
C of lead and bismuth, and that of the F phase is greater.)

ABST.UCT: This i7s a continuation of earlier investigations of the propei-ties of
beryl I ium.-doped germanium (r.TT v. 6, 2193, 1964, and earlier). The present investi-
gation was aimed at determining the influence of the.compensating impurity on the
ionization energy of the impurity conductivi-kity of the upper acceptor level (for non-
hydrogenlike centers). To this end, temperature measurements were made of the car-
rier density and the electric conductivity in the temperature faterval 300 - 55K.
The procedure far obtaining the samples and of the temperature measurements was de-
scribed in the earlier paper. The results show that for most samples the carrier
density depends exponentially on the reciprocal temperature. The ionization energy.
of these samples at higher temperatures is calculated and the values are listed in
a table. An ana3.ysis of the temperature dependence of the Hall mobility has shown I
that-,at-low.temperatures scattering of the carriers by charge centers predominates.
.Card-
ACC NRt AP6036999
The densities of the beryllium and of the phosphorus calculated from there data are
also listed. In spite of the fact that the ionization energies were obtained for
samples with different acceptor densities, the dependence of the ionization energy
of the impurity conductivity on the concentration of the donor impurity agrees well
with the standard theoretical formula. It is proposed on this basis that. the change
of the ionization energy occurring with increasing donor density is due to the action
of the negatively sing2y-charged acceptors. At higher temperatures~ the ionization
energy is a'function,of the temperature, this being due,-to a reduction in the screen-
ing of the acceptors. The author thanks V. S. Vavilov,.N. A. Penin, and V. V. Ostro-

TEXT: The trapping of electrons on the E 4 level of gold in Au-doped
n-type germanium was investigated at hydrogen temperature. The
photoconduction of single-crystal specimens was determined in a He
cryostat evacuated to -10-2 mm, Hg. The heat emission of a crucible furnace
was filtered through Ge and Sb-In filters. The damping periods of the
photoconduction of the specimens were measured for two different directionW
of current passage. If the contacts of the samples are_of,high qualityp
the damping of photocanduction can be described by exp( t/,'~). The
c;_efficients--O of electron trapping on the E level of gold were-

dependence of the trapping cross section is described by s*exp(-F,/kT),
where E is the activation energy. The dependence of'~on T increases
with increasing Sb content. This confirms the authors' conclusions
as to the effect of electron adhesion to Sb ions. The temperature
dependence of the trapping cross section shows no signs of a strong,
influence of the potential barrier around the centers upon the trapping
processes. There are 5 figures and I table.

PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 12, Pp. 3106-3109
TEXT: Germanium specimens containing impurities of elements of the
third and fifth groups have been studied repeatedly at the temperatures
of liquid helium (Refs. 1-9), but there are no data available on the
variations of ionization energy of lithium in germanium and on the electri-
cal conductivity of lithium-doped germanium at low temperatures, This
work was intended-go fill this gap. As Li in Ge has a diffusion coef-
ficient of D=1.10 cm2 /sec at 5000C, diffusion of Li into Ge at
elevated temperature is the best method of introducing lithium. The
germanium specimens were ground, etched, purified, and annealed in vauo
at 4900C for 4-8 hrs, depending on the size of the specimen. The annealing
was done with an Li-Fb alloy, from which Li diffused into Ge. Starting
materials were p-type and n-type germanium having a resistivity of

resistivity at 3000K from 6.5 to 0.58 ohm.cm, and ionization energy from
9.3 to 9.4 kev. The Hall constant (R) and the variation of resi3tivity
under the action of a magnetic field were measured as well. This was done
in liquid helium; the temperature of the specimens was determined from the
saturation pressure. The measurements in the magnetic field were made a+

and the EF pressure was less than 100 mm Hg. In the range up to 0.5 g, the accuracy
iof the microbalance measurements were approximately 1.8-2xlO-6 g. Prior to treat-
ment with Hr, samples of oxidized silicon were treated with fluorine. The depend-
ence of the removal of the oxide layer from the silic6n surface upon the duration of
ithe HF treatments is graphed. In the case of surface oxidation with dry oxygen,
with fluorine had very small effect on the rate of oxide removal by
pretreatment
treatment with HF. In the case of surface oxidized with steam in argon,
:the average rate of oxide removal was 0.04.10-6 g/CM2imin in the case of pretreat-
,ment with fluorine and 12.10-6 g/cm-min without such pretreatment. The effect of

TITLEs The Composition and Y!"eTa'of XyloleA a By-Product of
the Coal Carbonization Process
PERIODICALt Koks i khimiya, 1960, No.8, PP-41-44
TEXT: The composition of technical xylole, a by-product of the
coal carbonization process, was little investigated, mainly due to
lack of reliable methods and the lack of demand for the individual
isomers. In the paper, the yield and composition of xylole
produced on 9 coking works was investigated using mean dynamic
samples for the fourth quarter of 1957. In addition to xylole
fraction a part of xylole remains in heavy benzole and solvent
naphtha; it was therefore necessary to determine the content of
xylole in the above two products (Table 1). The determination of
the xylole content was done by careful rectificationusing a
column equivalent to 30 theoretical plates at reflux ratio of 5-6.
whereupon the fraction boiling at 135.0 to 144-5*C was considered
as xylole. The distribution of xylole between the individual
products was found to be as followst 78.8% pure xylole fraction

(GOST io465-39), 13.1% solvent naphtha (GOST 1923-50) and
8.1% heavy benzole. The content of the individual isomers in
technical xylole as well as in xylole separated from solvent
naphtha and heavy benzole was determined by the spectrophotometric
method. In addition, paraxylole was determined cryostopically
and wethaxylole was determined by the usual method through
trinitromethaxylole. Non-aromatic admixtures (paraffins and
naphthenes) were determined spectrophotometrically (the difference
between 100 and the sum of determined aromatics) and by the usual
method; sulphonation with 98% sulphuric acid (at 200 for 20 min).
The zontent of toluol was determined by rectification. The
composition of xyloles from the individual works was found to be
similar and is given in Table 2. on the averagc-, the composition
of technical xylole was as follows, in % a ethylbenzene 4.8;
paraxylene 21.1; methaxylene 58.0; orthoxylene 13.5;
t-oluene 1.1~1; non-aromatic and other admixtures 1.3. The
composition of xyloles separated from solvent naphtha and heavy

PEPRIODICAL: Koks i Khimiya, 1958, Nr 2, pp 44 - 46 (USSR)
ABSTRACT: A new standard for benzole for synthesis I, introduced
in September, 1957, required a very low concentration of
thiophene (0.005Pilo). An investigation was carried out in order
to study the process of purification of benzole-toluole fracti
L
up to the limits required for the benzole synthesis I and to
develop the optimum scheme for the production of such benzole.
The investigation of the appropriate fractions from Zaporozhe
T
and Bagleysk Coke Oven 470 rks (Table 1) under laboratory
conditions was carried out. At first 7 a direct Tuiashing of the
whole fractions was tested (Table 2); the results obtained
indicated that this method of purification is unprofitable.
Therefore, the following investigations were carried out:
1) Separation of BTX (mixed) fraction into a narrow benzole
fraction and a toluole-xylole fraction with their subsequent
treatment to a --equired purity; 2) The usual washing of
mixed fraction to limits required to obtain pure products
