ABSTRACTs Experiments were performed to study the stressed state of cylindrical shells
with reinforced and nonreinforced circular, squarep and rectengular openings in
tio
tenaion and in torsion. The experimental method used is the one of photoelas
coveringsp in which the surface of the shell is covered with a thin covering of an
optically active material. Shell deformations under loading are transmitted to the
photoelastic covering and are manifested in the covering as the dual wave radiation,
which is measured with.tho aid of a polarization device for reflected light. The

TEXT, The physical properties of CdSb were studied by
measuring the temperature dependence of the electrical
conductivity and the Hall effect on ten specimens of differing
purities, using the.graphical method of W.Dunlap (Ref.2-..Fhvs. Rev,
1950, 79, 286). The CdSb was produced by using spectrally pure
components obtained by multiple vacuum distillation. During
fusion, continuous stirring was employed and the single crystals
were grosin by zone fusion in a nitrogen atmosphere. The
measurements were made.on uniform single crystal specimens which
were carefully thermostated inside a liquid, The purest speclime%!!-

the temperature dependence of the electrical conductivity and of the
Hall effect. In the temperature range 333 to 3500K, an inversion of
the sign of the Hall effect was observed,, the purer the specimens
the lower was the point of inversion on the temperature scale,, Th e
ratio of the Hall mobility b of electrons to that of hole3 for two
of the specimens were determinedby the formula

where Rs i-S the Hall effect in the saturation range of the curvei
Rmax is the Hall effect at the point of the maximum R(T). In the
given case for T = 333"K, b,= 1.135 and for T 3115*Kj b = 1.390.
As was shown by Dunlap and by Hunter (Ref.5.' PhYs. Rev., 1954, 94.1

the specific resistance can be conveniently interpreted by means
of -the* graphical plotting of R/P as a function.of which has

in conductivity, which indicates limited solubility of these ale-,
ments in CdSb. Specific thermal emf increased with an increase-in
Cu,~Ge, and Sn content at room temperature, but decreased somewhat

heat treatment. Thu..s.. a, specimen with 4.67%',Te, heated.at 350C for
-30 hf-hhd cooled for 24 hr, shows an increase in specific clectro-
conductivity at high temperatures. Se and Te admixtures in excess
of one percent increase the melting point of the alloy to above
600C$ The reasons for tfils increase are not clear.,A turo-phase
regi'on in the specimens was observed by microanalysis. X-ray strut-

ABSTRACT: A procedure Is presented for obtaini4 singi~ cjZqal r~amplea of n-type
CdSb doped with group III elements. 'nic "pure"!CdSb was prepared by direct synthesis
from purified el,,-~-.ents with subsequent zone melting. The carrier density in the ob-
tained single-cr-jstal compound was 1015 CIC3. Samples with Ga and In impurities were
obtained by doping in the melt. The electric conductivity) the Hall effectp and the
thermal emf were measured frorn room temperature to the temperature of liquid nitrogen.i
Theresistance cf doped CdSb increases almost abruptly by several orders of magnitude
as the-temperat*are is decreased in'.a narrow temperature interval. For come namplen"
the Hall effect has a double Inversionp with the n-type region expanding with in-
creasing impurity concentration. The thermal emf also depends strongly on the temper-
6ture. The change in its sign as a function of the temperature corresponds to the
sign of the Hall coefficient. (Translation of abstract]

The thermoelectric conductivity was calculated on the basis of data obtained. The
highest value (1 x 10-3 deg-1) was obtained for samples doped (in the melt) with
1% silver. It was demonstrated that the silver and gold in CdSb were acceptors in
all the above quantities. The concentration of charge carriers increases with
increased chemical impurity. Maximum mobility of the carriers occurs with a 0.001%

A-IHSTRACT- The possibilities of detecting and visualizing dislocation
sources by means of electron-microscopic photographs of
alloys are investigated. Such investigations and attempts
to give a theoretical explanation of the phenomena were

always had "centers" (see Figs I and 2), which had an open
hexagonal or round shape. It was found that the distance
between the meshes increases with the distance from the,

If the first mesh is 0,47P removed from the center, between
the first and second mesh.there is a distance of 0,551l,
0,72V between the third and fourth; at greater distances
1,754 were measured. Such centers c an !cave two dislocations

ABSTRACT: The results of an electron microscopic investigation
of dimensions, form and structure of etelt figures in
age hardening aluminium alloys are discussed. lit the
table on P 388, data of the dimensions and shape of the
etch figures for various alloys are givon. The
dimensions of the figures change within very w.Lde limiLs
frow seveiral microns to a few teriths. It is
characteristic that for the majority of clitenched, sligtitl~
aged sl;ecimens the etch figures are straight-sided (Fig .1.)
and for the hardoned alloys they have an oval shal~e
(Fig 2). Their dimensions decrease in relation to tinie
and artificial ageing, when the hardness of tite allvy:s
increases. In Fig 3, an electron microgral,,it of an

P-157 represent plots.of.the, distribution of these. Almost all
the plotted curves show a maximum and* following that, a more or
less pronounced flat section or a further maximum. This leads to
the conclusion that maxima are characteristic for all crystalline
materials. This may be due to,the existenc of,two mechanisms of
formation and development of dislocation0lene of which leads to
fine the other to coarse slip lines or that two types of con-
diti;ns.may,exilst for the action of sources of dislocation in the
material. The dependence of the quantitative relations between
the two types of slip lines on the degree of,deformation leads to
the idea that the fine traces occur primarily during the initial
stages of deformation when the stress state of the material is
still relatively uniform, whilst the coarse stresses appear after
a considerable degree of deformation and are due to relatively non-
uniform stresses in the material. At present there is no
reliable theory or experimental data which would elucidate
satisfactorily,the existence of fine and coarse slipping. There are,
