this composition, fused onto steel 20GS-L possnss an erosion
resistance several times higher than that of heat-treated steel
lKhl3. The relationship between erosion resistance and hardness
of a material is complex and not fully understood. Al bronzes
containing 10 to 13% Al, both as cast and annealed, and in
particular as cast and quenched, possess a high erosion resistance
and can be recommended as materials for the manufacturs of machina
components subjected to cavitation erosion. Components of
hydraulii: machinery made from steel 20GS-L can be protected against
cavitation erosion by fusing Al bronzes containing 11 to 13% Al
onto them. The bronzes were fused onto steel 20GS-L in the

TEXT: It was found by Y.Y.Gavranok, M.Ya.Fuka and D.N.Bollshutkin
(Ref.li Fizika metallov i metallovedeniye, 1955, v.1, no.3, 494)
that erosion of metals under gravitation conditions is mainly thb
result of brittle fracture of crystals and that distortions of the
crystal lattice -aused'by stresses of zhe ae:ond'type develop only
slightly in the initial stages of erosion. In crder to obtain
further information on the mechanism of' i--avitation deaf'ruttion of
materials, the authors investigated the structure of metallic
monocrystals after they haire been 3ubjec~ted to 7avitation testing.
Monocrystals of commercially pure Al were prepared by means of
recrystallization annealing aluminium plates, 200 x 20 x 1 mm3,
which had first been deformed 3% in tension. Annealing was
carried out at a temperature of' 350"'C9 which was then raised to
590 and 6300C, the specimen3 boing soaked at ea.--h temperature for

4 hours and subseWA6ntly furnace-zooled. As a result,
monocrystals 70 x 20 r 1 mm3 we:re obtained. Spfcimens for
cavitation testing on a ma&netosTri,:'U1crL cibratoz were %ut from tht
monocrystal plates in the form of di-svs of 18 mm, diam&-~er. These
were secured to a nickel tube by means of a special holder and
subjected to cavitation testing in de-aerated tap wa-1:er at 250C for
15, 30, 45, 50, 90, 120 and 300 ae,:.. at a tube oscillation frequen.-y
of 7500 c./a and ionstant oscillaticn amplitude. X-ray pictures
were taken of the ipecimens before and after testing. It was
found that cavitation erosion of monocrystals of aluminium is
accompanied by intense break-down of these crystals into fragments,
so that already after 45 sel; the surface of the spe-timens becom tse
polycrystalline to a depth of 0.15 mm. the grain size being 10- M.
It was also found that the cavitation destruction of Al monoarystals
does not cause great lattice distortions of the second stress type.
The authors express the opinion that the brittle destruction of
metals under conditions of cavitation erosion may be due to
propagation of stress waves created by the impazt action of
cavitation bubbles. There are 6 figures and 5 references:

ABSTRACT: Materials used were the stainless steel IKhl3 and an
aluminium monocrystal. Cavitation tests were carried
out using a magnetostriction vibrator of a frequency of
7.5 kc/s and 0.065 mm amplitude. Each sample was photo-
graphed twice by a sharp focusing X-ray camera, focusing
the lines (110) and (220) . Distribution of the
influence of the breaking-up of the crystallites of the
mosaic and the size of microstresses. on the diffuse lines.
was found by the method of approximation and the method
of harmonic analysis. It was shown that cavitation
erosion occurred in a similar way to brittle fracture, which
has been shown to occur, in the main, by breaking up
of crystallites with no substantial microstresses. After
cavitation(3ros�on for up to 20 min, the (110) lines of
the lKh13 steel sample showed the presence of an axial
Cardl/3 texture [1103 normal to the surface of the sample. This

was produced by preferred disintegration of crystallites
with a favourable orientation. Monochromatic and poly-
chromatic radiations were used for the investigation of
aluminium. Figure la shows the presence of misorientation
of fragments of the monocrystal. Figures lb and c show
that in the initial stages of the tost, intensive
progressive granulation occurred in individual crystallite
fragments. Calculations showed that after 45 sec, the
surface was polycrystalline to a depth of 0.15 mm. No
substantial microstresses were found. Investigations were
also carried out on copper samples. The initial graln
size was 150 Ii and the grain size of the powder as a result
of cavitation erosion was 5 1;. No substantial micro-
deformation was noted. The results explain tile increased
cavitation stability of fine-grained alloys. The phase
changes occurring in the process of cavitation erosion in
the steel U7 were also studied. It was found that
tempering of the hardened steel occurred aild local
temperatures of 450 to 500 0C were reached. There are
4 figures and 4 Soviet references.

TEXT: The authors describe their use of the technique of micro-
examination of fractured surfaces, previously used by some other
investigators (Refs-1-3) in studies of alloy fracture, for getting
information on cavitation erosion of metals. Changes in relief
of eroded metal after cavitation tests of various durations and
the influence of heat treatment and chemical composition on
relief structure of alloys were st Idied. Annealed type lKhl31Y
chromium stainless steel, type Acarbon steel hardened to
martensite structure and tempered for 1 hour at 100-600 OC,
types Br.A2, BrA4 and Br.A6 aluminium bronzes in the annealed
state and types BrA10, BrA12 and Br.A13 in both annealed and
hardened states were studied. Cavitation tests were made with a
magnetostriction vibrator (Ref.4) at 75. cps in water. Micro-
examination of eroded specimens was effected with the a:id of

EM-3 electron microscope at X12X. The characteristic appearance
of brittle-fracture relief type 08KP steel and ductile fracture
of chromium-nickel steel are shown in Figure 1 (left-and right-
hand, respectively). Orientation and size of planes was also
determined and compared with erosion speed (Ref. 6). Fig. 2
illustrates the surface relief of type lKhl3 steel in the peri-
pheral and central parts of the specimen and after a 3-minute
test and the same after 90 minutes. The reliefs of type U7 steel
apecimens aftertempering at 100, 400 and 600 OC and cavitation
testing for 3 hours are compared in Figure 3 and those of Br.A2,
Br.A6 and Br.A13 aluminium bronzes after 3--hours' cavitation
testing in Fig. 4. The relief obtained with specimens of hardened
Br.A,10 and Br.A13 aluminium bronzes after 3-hours' testing is
shown in Fig. 5. With the alloys ~studled cavitation erosion
occurs by way of brittle fracture\of crystals. The size and mutual
orientation of planes from which crystals have broken away determine
the erosion stability of the alloy: the smaller the planes and th

TITLE: -Thermai and Mechanical Action of a Cavitation Zone

TEXT: The present work is an attempt to examine the change in
temperature and pressure impulses arising in the surface layers
of a solid in the cavitation zone. A magnetostriction vibrator
was used in the experiments with a constant amplitude of 0.06 min
and a frequency of 7.5 kc/s. Phase changes in a quenched U7
steel and Dl duralumin were investigated in the cavitation zone
by microhardness and X-ray investigations. Fig. 2 shows the
relation of microhardness with time of cavitation erosion.
Fig. 2a is for the steel and 2b for dural"in. The changes in
hardness show that the temperature of micro-voluines during
cavitation erosion reaches 470 0C. Fig. 3 shows the effect of
a prel'iminary tempering treatment at various temperatures on
hardness (Curve 2) and rate of erosion (Curve 1). The rate of
erosion is practically unchanged by preliminary heat treatments

up to 400 0C. This shows that the damage occurs on micro-
volumes of metal, the temperature of which is up to 1100 0C.
X-ray investigations show that the internal stresses arising
in the steel in the process of quenching are removed by
cavitation erosion. Similar results were obtained for duralumin.
During the experiments, -the duralumin became artificially aged,
showing that high temperatures are reached during cavitation
erosion.
The obtained results can be summarised thus:
1) the mechanical and the thermal effects in the cavitation
zone produced by the magnetobtriction vibrator were calculated.
It was found that in the case of using/7-5 IcS/s vibrator, the
pressure increases periodically to 550 kg/cm during a period
-5 -5 2
of about 10 sec and acts on an area of about 10 mm The
micro-volumesof the metal bordering on the cavitation bubble
are heated to 300 - 500 OC.
2) It was established that during the process of cavitation
erosion, hardened steel is being tempered at temperatures up

to 470 0C.
3) The speecb of cavitation erosion of steel hardened to obtain
a martensitic structure and of steel tempered at temperatures
below 400 OC are practically equal.

The.authors note that a white stripe is observed in the heating zone
during the macro-etching of welded,joint templates of perlite steels and that, ac-
cording to earlier investigations, this stripeis located in a zone corresponding
to heating of the base metal to int6rcritical temperatures. The need for study in
'this area is noted and it is--pointed -out that-simulation is the sole feasible me -
thod for such rebearche In-:this article, therefore, the problem of simulating the
white stripe in*velded joints is considered. In this connection, the authors pro-
pose that a well known method be: used, forthe p-urpose of simulation, involving
the gradient heating-of wedge.-shaped samples, in the tests described in the paper,

under different types and condition6 of welding. The authors emphasize that the
method described in this paper permits the study of mechanical properties only as
a function of structure. On,the other hand,,in actual welded joints., these pro-
perties may change somewhat due to~ihe field of stresses which develdp during
welding. However, such variations itill.inevitably be of only a quantitative, and
not a qualitative, nature. In this;,way, the.simulation methods proposed in this
article (that is, the "gradient heat-in& method" or the method involving the ma-
chining of separate samples from tho intercritical temperature interval) are con-
venient for,the stud- of the structiliral formation processes and for determining

ABSTRACT: A method of nondestructive inspectionAf th structure of products by
the increased-power trasonic method is vroposed XTh: method permits visual
observation of changes in the attenuation factor As well as recording of the
results of monitoring on a photographic plate. Apparatus for the method is
described (see Fig. 1). The frequency intervals of ultrasonic oscillations in
which (with a small frequency drift) the attenuation factor changes at a maximum
rate were established experimentally. Ultrasonic photographs were taken at 2.8
and 2.9 Ile. The accuracy of the method in determining grain size is 1-2 points

ANSLATION: A new method is p, Iroposed for studying metallic structures by mea2s of
.trasonic oscillations, using oscillations with a final amplitude of about 10 8-10-4
1. Thereby, the possibility of measuring the amplitude dependence of damping (y) was
lowedg as well an of analyzing the localized structure in small volumes. The 9-24n
ze dependence of y was studied for pearlitic, martensitic and austenitic grades of

Ltionship, was the awe for all of the steels. On samples of duraluminum D16, the us-
