and growth of fatigue cracks, the role of plastic d6formAtion
in fatigue fraptureo an accelerated method of deterMining
fatigue strength, the plotting of fatigue diagrams, and
various fatigue test methods. New data are presented on the
sensitivity of high-strength steel to stress concentration,
the effect of stress concentration on the criterion of fatigue
failure, the effect of the size factor on the strenkth of
metal under cyclic loads, and results of endurance tests of
various machine parts. Problems connected with cyclic metal
toughness, internal,friction, and the effect of corrosion
media and temperature on the fatigue strength of metals are
also discussed. No personalities are mentioned. Each article

T~XV: Additional information to literature data in presented making it
possible to evaluate the causes of decreasing cyclic strength of steel parts in
connection with contact phenomena. The authors determined the effect of the in-
terlayer material between the specimens and the machine clamps and of the inter-
layer thickness upon the cyclic strength of flat steel plates In the spot of con-
tact. The tests were made onCT-3(3t-3) steel specimens with the use ofY11-30
(UP-30) type machines, which produce plain bending of the specimen in one plane
at a symmetrical cycle with about 2000 frequency per 1 minute. The test basin
was 10 million cycles. The tests were made with differently thick presspahn, Zn,
All Cu, carbon and stainless steel specimens. The endurance limit was determined

from the fracture of the specimen or from crack formation. The data obtained con-
firm the effect of the interlayer material and their thickness upon the cyclic
strength. It is shown that the electric erosion factor may play an Important part
in the decrease of the cyclic strength. The authors believe that i3imultaneounly
the effect of other factors should also be taken into account, namely, stress
concentratlon,mechanical wear of the surface, and fretting- corros Ion. There are

stepped shafts due to hardening by roller burnishing is independent
of the scale of the modelling. The fatigue tests on specimens tith
diameters ranging from 20 to 160 Lnm in 40/::11 (40 KhN) and 40X (40
Kh) steels were carried out in order to ascertain the possibility
of replacing the former. Dimensions of the test-pieces and the

ABSTRACT: Stress concentrations caused by threading considerably decrease the fatigue
strength of cyclically loaded machine parts. The common method of cutting thread leadg
to an interruption of grain flow in rolled and forged materials, which adversely affects the
strength of details at the location of the thread. The formation of threads by cold-rolling
considerably reduces the unfavorable effect of stress concentrations which result -in plastic,
deformation of a metal surface layer in which residual compressive stresses are produced.'
The original grain flow is not cut but is deformed to follow the profile of the thread. The
technological process of thread-rolling insures higher production and is widely applied in
mass production of small screws, bolts, and other parts externally threaded.

ACCMON NR: AT 4014050
However, thread-rolling Is practicable only on details of relatively small diameter, up
to 40-50 mm, because higher pressure is required on the rollers with details of larger
diameters. Rolling devices are also more complex. Experiniontil investigations have
been performed and described in the past, showing that special finishing operations can
be applied at the bottom of larger cut threads to Increase the !;dA&-uc strength of details.
New investigatimis made in this field. by are described by the authors.* New
methods have been applied to produce plasLlc diAormation of metal surface, such as the
u~e of vibrating rollers for surface-rolling with the simultaneous application of a vibrational
impact load to produce a peening effect to a great depth (see Figs. 1 and 2 of the Enclosure).
These new devices are universal and can be applied to details of any size as attachments on
the lathe. Fatigue tests have been conducted by pulsating tension and by bending small and,
large specimens having threads of the buttress, metric, and tr:u11--,odal typic. These tests
have shown that strengthening of the thread botU.,,.-. 't)y pInstic deformation incroases the
carrying capacity of threaded 'details 1-1/2 - 2 tim-9 ai,.cl inore. This effect has been ob-
served on both small and large details (shafts up to 215 rrim in on different
types of steel, and with different types of c- '.,k:1 i., lo;idliiig. The infl-Pnoe of non-uniform

TMUNSLATION: The study concerned the causes of the deterioration in fatQue
strength of steel parts in contact areas. The combined effects of stres:; concen-
trations, surface eroaion caused by the action of the therwelectric curr(!nt,
mechanical abEasion of the surface and frit~ing corrosion were found to comprise

;ABSTRACT: The purpose of this work was a study of changing endurance limit (fati-
gue) of notched cold hardened samplas due to prolonged storage (10 years). Rods
;.of type 40 steel were surface rolledp Increasing their surface hardness frod HV
187 to 240 and creating considerabla comprenaing stressed at the surface (50-60
kg/=2). They were notched with a cutter after rolling* The fatigue of these
samples vu compared with that of other samples which were not cold hardemed. The
samples were tested for fatigue every year for ten years. It was found that In-
creased strength of samples with induced residuary stresses does not change during
protracted storage at normal temperatures, Orig. art* has: two figures,, no

icold working gave greater improvements than the plating. A c hination treat-
iment, cold working of the nut holes and zinc plating of the bolts proved most effec-
tive; with all four types of steels, the endurance limits of the joints increased by,
107-250% and both the salt concentration and the nature of corrosive medium did not
have any effect on the wear resistance of the joint. Zinc plating of bolts made of

WN-3B steel did not improve corrosion resistance. The zinc plating of the cold

ABSTRACT: Irvactual --ure -vessels are often subjected to fluctuating
stresses, therefore, stress calculations based on static loads alone are not
reliable. The object of this in7estigation was to correlato the effects of static
and of pulsating loads. The test specimen " its stress diagram are shown in
Fig. I on the Enclosure (bt i_- the uircuiriferential and b7 t-lis longitudinal stress) .
Seamless tubing was used for the cylindrical part, and the tensile strength of
its material was determined by pre "'inary teats. Four variations of the specimen,

TITLE- Nozzles of -the A-547r Semi-Automatic Machine for Welding
in Carbon Dioxide
PERIODICAL- Svarochnoye proizvodstvo, 19061, No. 4, PP. 37 - -58
TEXT- Welding in carbon dioxide with consumable electrode is used at
the Chelyabinsk Tractor Plant for joining tractor parts on the A-547r Semi-auto-
matic machine, where the gas flow is directed by a chromeplated brass nozzle
(Fig. 1), placed on the rubber housing of the burner tip, The use of this nozzle
presents however, a series of deficiencies, such as short-circuits of the weld-
ing current; sticking of metal splashings to the internal nozzle surface, and
short service life of the nczzle. The laboratory of mineral ceramics at the
Plant developed ceramic nOZ2;les to replace 'the chrome-plated brass nozzles, pre-
pared in a metallic mold by press-forming from a ceramic mass of 32 - 14% mois-
ture, The components of the ceramic material were dried, crushed, screened,
and mixed during 8 h. The material was then wetted with water to 28 - 30% for

ABSTRACT: Oscillators which gell"Ierate sinusoidal oscillations based on various
physical principles are used in experimental determination of frequency character- I-
istics of elements. One of the possible design principles is based on the rotation
of two electrodes in an electrolytic bath. If the field in the bath is homogeneous,
the voltage between the electrodes varies in accordance with sinusoidal law. The
errors of such an oscillator are determined by the inaccuracy of the equipotential
surfaces. The amplitude of the output signal of such'an oscillator is stable, does

not depend on frequency, and is easily adjusted. Frequency stability is determined
by the drive speed. At a frequency of 3-4 cps, the amplitude becomes unstable
and frequency distortion takes place. To raise the upper limit of the frequency,
a circuit is proposed which has been used in designing and testing osciUators with
two and four pairs of poles. Their accuracy depends on the accuracy of the con-
struction and assembly of the electrodes. Tests have revealed the presence of
subharmonic of 2-316 in the voltage curve.caused by the noncoincidence of the
rotation axis of the output electrode with the field axis. There is one illustration
and a bibliography of 4 titles. [Translation of abstract] [DWI
