Author's conclusions-, 1, Carbon steels with a laminated pearlitic
structure are more wear-resistant than steels with a granular pear3itic
atnacture. 2. An increase in the amount of laminar pearlite results in
a drop in the rate of wear, especially in hypoeatectoid steels.

Author's conclusions (in part): 1. An increase in the quantity of
special carbides in annealed and hardened chrome steels increases
their wear resistance. 2. A given quantity of cubic crystals of
chromium carbide imparts greater wear resistance than the same
quantity of trigonal carbides., other conditions being equal,

TEXT: The object of the present investigation was to study
the effect of electro-deposited zinc and cadmium coatings (applied
singly or together) on the mechanical properties of steels WkA
(38Kh-Q, 3oircR (3OKhGSA), IBXHBA (18KhNVA) and 1X19H9T (lKhl8N9T).
The standard test pieces, hardened and tempered, were zinc-plated
in a cyanide electrolyte, the same type of electrolyte having been
used for cadmium plating. The composite coatings were applied by
first depositing a 3 micron thick cadmium coating and then a 3
micron thick layer of zinc. The thickness of zinc and cadmium
coatin-s', when applied oingly, was 6 microns. The mechanical tests
included tensile tests and impact tests, carried out at room and
elevated terape.ratures (200-700*C), as well as creep tests at high
temperatures. It was established that cadmium or cadmium + zinc
coatinc-s, considerably reduce the ductility of steels studied at

pronounced. None of the coatings studied affects the impact

TEXTt The object of the present investigation was to study the
effect of mechanical and'thermal treatment on the properties of
stoel 1OKhl2NVMFA which is a material combining relatively good
corrosion resistance with high stringth at room and elevated
temperatures. (The composition of this steel is such that it
contains no free ferrite; since the strengthening alloying
additions, i.e. VT, Mo and V, increase the range of the a-phase,
steels of this type contain no more than 12 to 15% Cr and 2% Ni.)
The experiments were conducted on strip (2 mm thick), possessing
the following properties-: U.T.S. (cyb) = 67 kg/mm,2.

depth of indentation in the trichsen test 11.4 mm;
number of bending reversals through l8o* 9. The tensile tests
were conducted on test pieces cut from the strip in the direction
of rolling. The high-temperature properties were determined by
short-time tensile tests, carried out at a rate of strain of
0.3. E/min, where I is the gauge length of the test piece. In
the heat treatment experiments, the specimens were hardened by
oil- or air-quenching; they were cooled in air after tempering.
The fatigue tests were carried out on a machine operating at 1400
to 1500 rev/min, the duration of each test being 10 cycles. The
results can be summarized an follows. (1) The optimum heat
treatment of the steel studied consists in heating it to 900 to
10006C, quenching in air or oil, and tempering at 500 to 5300C.
The mechanical properties of steel, heat treated in this way, are:
Ob = 115 kg/mm2j 00.2 = 105 kg/mm2j 6 = 10%; RC (Rockwell
hardness) = 40. Secondary hardening takes place during tempering
at 450 to 500*C but the plasticity of steel is not affected by
this change. (2) The effect of temperature on the properties of
steel 1OKhl2NVMFA,is illustrated in Fig.3, where b and Ob are

(4) The effects of plastic deformation caused by various fabrication
Processes can be removed by intermittent annealing at 600 to 700*C-
Annealing at higher temperatures is not possible because the steel

results of metallographic examination and mechanical tests

is illustrated in Fig.6, where the endurance limit (a-I, kg/mm2)

TEXT: The influence of cathodic polarization conditions in acid and
alkaline solutions on the hydrogen embrittlement (HE) of carbon steel is
pointed out. The kinetics of hydrogen adsorption and the HE of steel were
studied. The stimulating action of cyanides and sulfides on hydro,gen
adsorption in cathodic polarization of steel in alkaline solutions was
verified. Reduction of hydrogenation in cathodic treatment of tempered
metal in acid media is achieved by adding CrO3 to the electrolyte.
Additions to alkaline electrolytes do not reduce HE considerably. The
strongest tendency to HE displays cold-deformed steel without sub3equent
annealing. This proves the predominant influence of the metal stress on

the amount of 11E. The increase in brittleness in electroplating is due to
the oresence of internal stresses in the deposits and to the hydrogen
adsorption of the steel backing. The deposition of thin layers is
accompanied by an increase in brittleness exceeding that of thick ones.
The increase in brittleness is reduced with increasing thickness of the
deposit. An intensification of the electrodeposition process may, on one
hand, intensify the increase in brittleness due to decrease.in current
yield when the plating process is accelerated, and on the other - reduce
the growth in brittleness due to a more rapid formation of deposit, serving
as a barrier for the hydrogen penetration into the metal. Plating in
cyanide electrolytes (zinc, cadmium, copper plating) is accompanied by
considerably higher hydrogen adsorption than in acid ones. In acid baths
the current yield is increased and cyanides intensifying hydrogen
adsorption are absent. Nickel-plating leads to an increase in brittleness
of temDered metal. stronger than that of quenched metal, This is due to the
predominant influence of stresses in the deposit. Any changes in chromium
plating method, thickness of Cr deposit, dechroming conditions (anodic
etching of chromium), interruptions of the current in chrome-plating have
different effecto on the brittlenese of quenched and tempered steels. In

chrome-plating of tempered steels this is explained by a connection
between increase in brittleness and the presence of internal stresses in
the deposit - and for quenched steels it is assumed to be mainly due to
hydrogenation of the backing. Electroplating results in a decrease of
the fatigue limit, especially for quenched steel coated with nickel, then
with chromium, zinc, and copper. The main effect on the recovery of
plastic properties of steel after cathodic degreasing displays the
temperature of the liquid medium in which dehydrogenation takes Dlace;
the effect of anodic aging is negligible. Electrolytic degreasing and
dipping change the brittleness of steel in different directions which
arises in subsequent Tnetalplating in dependence on various factors, among
which the structure of the basic metal is the most important one. Also
shape and thickness of metal coatings and the conditions of electro-
deposition have an influence: thin Cu and Ni backings reduce the
brittleness arising in subsequent chrome-plating; thick Cu backings may
intensify brittleness. Addition of oxidizers (CrO 39 UnO 4) to acid
solutions is little effective with respect to a decrease in brittleness
in electrolytic cathodic treatment of quenched metal, but reduces the
increase in brittleness in etching (din) without current. Increase of

current yield, current reversal, and stirring do not reduce the brittleness
of quenched steel, but reduce that of tempered steel. Aging restores the
plastic properties only of parts which were subjected to cathodic,
treatment without galvanic deposition; after polarization in alkali,
plasticity is restored more rapidly and more completely in aging than
after polarization in acids. Aging of steel parts with deposits may
also lead to an increase in brittleness. [Abstracter's note: Complete

ABSTRACT: In order to establish whether structural defects, and
particularly dislocations~, can serve as traps for the capture-of
non-equilibrium holes at low temperatures, a systematic investiga-
tion was made of capture in n-Ge ~n which excess dislocations were
produced by pla5tic deformation. The results indicate that the
trap concentration increases with decreasing temperature. The dis-
location traps are capable of causing nonlinear photoconductivity

effects. The principal results of the research were reported by
the authors elsewhere (UFZh v. 8, 1179, 1963). The article de-
scribes the preparation of the specimens and the preliminary mea-
surements, and relates how the presence of traps due to plastic de-
formation was -lemonstrated. It is shown that in addition to.,serving
us the main traps with which the observed of long-time photoconduc-
tivity relaxation is associated, the dislocations act simultaneously
as recombination centers. In deformed specimens they determine the
lifetimes of clectron-hole pairs. At considerable deformation, when
10 7 cm- 2,
the dislocation density exceeds the capture of minority
carriers (holeg) is observed already at room temperature. It is
concluded that the similarity between the capture phenomena in the
deformea and initial specimens indicates that the traps have the
,same nature in both casas. The authors thank Academician of AN

recombination. GB of the second kind have no recombinative activity, but
exhibit an intense photovol *taic effect and photoconductivity. The latter
indicates current gain in the GB. X-ray studies support the assumption
that GB of the first kind are related to simple small-angle lineages,
whereas GB of the second kind are representative of lineages of wide
angles. In the following discussion, GB is assumed to contain a number of
acceptor-type quantum levels. The local negative charges resulting from
electrons produce a potential barrier in the region of lineage. The
electron current passing through the barribr is treated in analogy to
the diode theory of the barrier layer. The hole current passing through
GB is computed as in the case of n-p junction. The author concluded that
GB can affect non-equilibrium carriers in two ways. In the case of a low
barrier) recombination on GB predominates (GB of the first kind, with a
dislocation structure being assumed). GB of the second kind shows a
"feed-in-feed-out'leffect consisting in the immediate expulsion of A'hole
from the barrier region for every incoming surplus hole. For this kind
of GB, an n-p'-n structure (corresponding to a high potential barrier)
is assumed. The author thanks Professor Doctor L. Sosnowski and

ABSTRACT: The authors describe a noncontact method for '11-IM
determining the resistivity of semiconductors by capac-
itive coupling of *the crystal to the tank. circuit of a C
high-frequency oscillator. The circuit of the measure-
ment oscillator is shown in the figure. The crystal is
connected in parallel to the capacitor C in the oscill-
ator tank circuit through coupling capucitors C S1 and
C S2* The electrodes are two metal plates or tapes
clamped to the cry~'-tal surface through a layer of

dielectr"'c foil. The coupling capacitance is set up between the electrodes and the
crystal. The circuit is a modified Meissner oscillator operating at high grid currentsI.
The measurements frequcncy is about 4.5 Me. The grid current is measured by, a milllltm~,
meter connected in series with an hf choke. The grid ciLrrent I s -ieasured an a flmctior~I
of frequency (or capacitance of C) has a number of extrema. The oscillator frequency
is selected to operate on one of the extremum values of I Curves are given showing
Is as a fitnetion of the interelectrode resistance of the crystal R x for various
effective coupling capacitances. These curves show a characteristic minimum which
increases with coupling capacitance. The region of considerable change in I extends
over values of R X ranging from 10 9 to 100 KO when the coupling capacitance is of the
order of several a6zen )j)jf. This range may be used fur determining the unknown value
of R x from measurements of -the grid current. A variable resistor R=0-5 KQ is connecteo
in series with the coupling capacitance and the resistance of the crystal. This
resistance may be adjusted to give the minimum grid current when -r;he resistance R x is
too low. The cathode potentiometer is adjusted for zero setting. The electrodes are
made in the form of rollers from sheets of brass foil measuring about 20x8 mm. Resist
ivities from about 10 11-cm, to 10 KQ-cm way be measured and this range may be extended
to 100 KQ-cm by changing the oscillator frequency. The accuracy of the measurement
