Specific features in thermal fatigue tests of... A006/A101
ance. Four types of speciriens"are proposed. Bi-axial thermal stresses, attaining
maximum values on the surface are characteristic for flat specimens: cylindric-
-shaped samples are characterized by volumetric thermal stresses, whone longl-
tudinal components are highest on the surface and axis; plane thermal stresses
with maximum values of the longitudinal components in the thin ribs, are charac-
terfstic for triangular and trough-shaped specimens. Heating should be performed
as if under operational conditions; the cooling rate should range between 50 to
1100 degree/sec; cooling by a compressed air jet is recommended. A criterion for
a general quantitative evzIluation of thermal fatigue does not exist. Criteria
used are thermal fatigue curves, which relate the number of cycles until the
breakdown to the magnitude of the temperature drop, total (elastic and plastic)
deformation, accumulated deformation, or to reference'stresses, calculated from
deformation values. Test results should be analyzed by methods of mathematical
statistics. Method I is recommended for studying the nature of thermal fatigue
and to determine a quantitative relationship between the parameters determining
thermal fatigue resistance. Method II is recommended for determining thermal
fatigue. There are 5 figures.

this method was extended to the case of reentrant resonator. The author presents
formulae of relations between r and transmission coefficient T of the reentrant

was smaller for the higher frequencies. The measurement curves (AH(t),
AH(f), 6-(t); w-magnetization) show that 4H(t) in polyqrystalline samples is'
similar-to that in single cry5tals. At low frequencies the low-temperature
broadening of the resonance curve has another cause than at high frequen-
cies: in the former it is due to temperature dependence of the relaxation
frequency, as well as to magnetization, and the effect of domain structure,

whereas in the latter it'is an effect of impurities, and principally an
effect of the maximum which they cause at low tempbratures. The'broadening
of the'resonance curve near the Curie point is due to the temperature

ions in'the intensity of magnetizdtion. Unlike in single crystals,
of 3Y203* 5Pe2 0,, the 6H -here depends notably on the freque6c .y, probably I
because of magnetic inhomoCeneity. There are 4 figures.

The temperature and frequency dependences of the ferromagnetic

TEXT: A report in given on experimental investigation of the temperature
dependence (between room temperature and the Curie point) and frequency
dependence (at tile 4 fixed frequencies 1000, 1,4961 2590 and 9200 44c ) of
,the ferromagnetic resonance line width of sphexical ferrite monocrystals
having garnet structure. Polycrystalline specimens of this type were
already investigated by B. M. Lebed', Yu. bl. Yakovlev (FTT, 4, 1695Y 1962).
It is pointed out that their values for the frequency dependence of the
line width of ferrites are inconsistent with those obtained by R. C.
Le Grow et a] (Phys. Rev-, 110, 1311, 1958) and byj. F. Dillon (Phys.
Rev., 105, 759, 1957). The monocrystals of the ferrite

garnets were obtained from a PbO melt at a.cooling rate of 20/hour. The
measuring methods are described in the previous work first cited. The
temperature dependence of the line width LH has the same character at
ail frequencies. The line width of all specimens increases strongly in
.the vicinity of the Curie point. The characteristic temperature at which
the I~ine width of the iron yttrium garnets changes discontinuously ia
determined by tha passage throu6h the frequency 6)c/2 of the lower limit
of the spin-wave spectrum. Using a monocrystalline disk made from yttrium
iron garnet, the measurements of the temperature dependence of 8H were
chocked and found to be correct. This discontinuous change in the line
width is due to it nonlinear three-magnon process with a low threshold field
hthr N, 2 inilli6ersteds. The,line width of optically polished yttrium iron
garnets,is, in practice, independent of the frequency. The line width LH
of such garnets as have a rough surface depends weakly on the frequency.
As the frequency increases from 1000 to 9200 Mop 6H increases by almost
1001/a', which cannot be explained by relaxatJ,)n processes due to
microscopic magnetic inhomogeneities. Owi,,jg to the discrepancies between

mechanism of relaxation depends on the frequency. Two relaxation
mechanisms seem to be in operation. 1. A fluctuation mechanism,
which causes the line width to increase at high temperatures. 2. A
mechanism which leads to an increase in the line width of low tem-
peratures. At, each frequency, the temperature dependence was such
that the line width increased at low and at high temperatures, with
a fairly flat minimum in an intermediate region. It is shown that
both relaxation mechanisms are inherent in an ideal ferromagnet.

,ABSTRACT: To clarify some of the doubtful assumptions made in
earlier deductions by various authors that the maxima of the ferro-
magnetic resonance line broadening are in accord with the spin-wave
theory, the authors 'measured the temperature dependence of the line
width of polycrystalline and single-crystal samples of yttrium iron
garnet Y3FeSO12 and single crystal nickel ferrite WiFe204. The mea-
surements were made at frequencies 1000, 1496, 2590, and 2950 Mcs

'using amethod describe, by t 6 authors earlie'r (PTE ilo.~6, 107,
1956). A maximum was observed on the temperature dependence of the
line width at 2590 and 2950 Mcs at a temperature corresponding to
magnetization at which the frequency of the homogeneous precession
is contained in the spin-wave band. No maximum was observed at
1000 and 1496 Mcs. The ratio of the homogeneous precession fre-
quency to the magnetization frequency was constant for both frequen-
cies. The observed intensity of the line-width peaks at 2950 and
Mcsi and-7the absence of peaks at 1496 and,1000 Mcs, is in ac-
cord with the theory of line broadening in polycrystalline ferrites,
proposed by Schlomann (Phys. Chem. Solids v. 6, 242, 1958). -It is
shown that if the homogeneous precession frequency lies within the
spin-wave spectrum, the magnitude of the line broadening does not
agree with the fichlomann theory. Possible causes for this discrep-
ancy are discusned. "In conclusion the authors thank A. G. Gurevich.

TITIX; Angular dependence of the frequency of ferromagnetic resonance in an arbi-
trarily oriented plane of a cubic crystal
SOURCE: Fizika tverdogo tela, v. 8, noo 11, 1966, 340T-34io
TOPIC TAGS: ferromagnetic resonance, cubic crystal, magnetization, magnetic
anisotropy, crystal orientation
ABSTRACT: In viov of the fact that previouali derived formulas for the resonant
frequencies, with allowance for the crystallographic anisotropy, were confined to
particular directions of the magnetic field, the authors derive present more general
formulas that apply to a number of different particular cases. A general formula is
derived for the angular dependence of the resonant frequency for the case when the
constant magnetic field lies in a plane arbitrarily oriented relative to the crystal-
lographic axis of a cubic lattice. 'The calculation method is the same as that des-
cribed by A. G. Gurevich (FerrIity na. sverkhvysokikh chastotakh (Ferrites at microwave
Frequencies] Fizmatgiz, 1960) or by 1. H. McDonald (Proc. Physo Soc., v. A64, 9689

factors of the crystallographic,anisotropy. Several particular cases (weak magaeti-

is also shown that when the magetization and the field vectors coincide (When the ani--
sotropy field is much weaker than the main field), the (111) plane is an almost
isotropic plane in a cubic crystal (0.01% anisotropy).; Orig.*art. hass 1 figure and

ABSTR_ACT: Hydraulic model simulation, with subsequent. verification of the re-
sults obtained on A] and steel ingots is used to study distribution of
liquid (L) flows within a mold (M) during bottom pouring and of the
influence of these flows upon the formation of the external layers of
an ingot. The experiments were run on models of big-end-down
bottom- pouring M, made of organic glass, in 1:4 natural size with
similar scaling of the conditions of delivery of L tbereto. Water is
used to simulate the metal, Measurement of the velocity head of the
L is made at various levels of the model.. The investigations are run
at various rates of filling and at va rious filling 'levels. 'it is found

from the vertical toward the wall opposite to the side from which the L is introduced
and that. all the stream parameters depend upon the heigbi to which the M is filled.
It is shown that the angle formed by flic M axis -and the boundary of the stream fac-
ing the wall opposite the side of L introduction grows W1.1h increase in filling rate
and with rise in the L level. in the M, wftfle the ang3.e between the opposite boundary
of the stream and the M axis reduces with. these changes in parameters. The maxi-
mum changes in these angles occur at. a hei.ght equal to from 16 to 28 diameters of
the runner bringing the L to the M. Observations have established the presence of
downcurrents forming at the initial stage of filling, both at the M wall adjacent to
the center wall and at the opposite %vall. As The L level in the M rises, the first of
these streams become stronger and the latter virtually di.sappear, becoming up-
currents. The angle of divergence of the stream is identical in all directions and
comes to -65-700. An investigation of ri.ngs cut out of hollow sleeves formed by
draining the unsolidified ingot cores confirmed the existence and the nature of the
flows described above. The interior surface of the rings cut from these steel
sleeves revealed a graininess, which i5 particularly notice-able on the washed side
of the skin. It is also found that longitudinal outside cracks in ingots form where
the skin is thinnest. The tendency to longit udinal- crack formation rises with ingot
height.

ABSTRACT: 7ha enerUy and angular distributions of LO nuclei ejected from C12,

a: the, aj,acted Lis nucleus is ~ormad by direct reaction.of the incident proton
with a Be9 cluster within the C12 nucleus. The spectrum of Lis from A127 was calcu-
lated on theassumption that it is formed from a Be 9 cluster and is subject to ab-
sorption by t,',.e rttsidual nuclous. Good a.-rouizent with experiment was found. The
_sDectrum of Lis from V51 was calculated on the assumption that Lis is formed only
during the evapora .tion stage ol the reaction. Fair agreement with experiment was
obtained for large expulsion angles, but the observed yi-eld at low angles was con-
siderably greater than tha calculated. It is concluded that direct reactions with
clusters in the peripheral region make a significant contribution in this case also.

~ABSTRACT.- The purpose of -the investigation was to study the charac-
teristics of the transfer of large momenta,to residual nuclei, and
to ascertain the extent to.wbich the interaction botween the incident,
;and bound nucleons is quasi-free. The singularities in the produc-
.Ition of fast residual nuclei in the reaction Be9(p, 2Nx7r)Li8 were in-'
-vestigated to this end. The reasons for choosing B.e9 as a target
nucleus and the experimental procedure are described., An analysis

of the results indicates that at least up to 750 MeV/c the: large
.,momentum transfer to the residual nuclei Lia can be explained by
~assuming quasi-free interaction between the incident,-proton and the
:.nucleon. In view of its importance, it is concluded that a review
:of this process is necessary with allowance for elastic scattering,
which was neglected in the present analysis, and with an examination
~of the alternate possibility of transfer'!of large momentum to the
~Lia nucleus by knock-on from the Be9 nucleus. "In conclusion the

TEXT: The authors mention the effect of vibration on metal crystallization
and describe tests performed with a vibration pouring device (Fig.1), designed
by the members of the Institut metallurgii imeni A.A. AN SSSR
stitute of Metallurgy imeni A.A. Baykov of the AS USSR), G.F. Balandin and
V.A. Petrunichev. Fig.2 shows macrosections of A2 aluminum ingots. The in-
got shown in Fig.2a was poured with the aid of a non-vibrating device, ingot
shown in Fig.2b through a vibrating funnel with a frequency of 230 oscilla-
ti.ons/sec,, an amplitude of 0.1 mm, power 1 kw, temperature of liquid alu-
minual 720 C, ingot weight 2 kg and pouring time 4 seconds. The ingot obtain-
ed with the vibration pouring device'was finer grained and its plasticity
increased by 20% (see Table). Tests showed that casting through a vibrating
pouring cievice produces the same effect as pouring into vibrating molds. A

considerable crushing of grains in the ingots., indicates an increase of the
crystallization centers in the liquid metal during vibration. Fig.3 shows
specimens on which the tendency of aluminum alloys to hot cracks was tested.
The specimen of AD1 alaminum (Fig.3a) wan poured through a non-vibrating
funnel; the one shown in Fig-3b was poured through a vibrating funnel at
7200C and showed no hot cracks. As the metal is poured through the vibrat-
ing funnel the walls become coated with a hard layer of metal. This layer
is broken by the vibration of overheated liquid metal and solid metal pieces
are carried into the mold together with liquid metal, where they melt partly
or completely. If no complete melting is reached by the time the metal be-
gins to solidify, these solid phases become centers of crystallization. Fig-4
shows a macrophotograph of the longitudinal section of the coating removed
from the funnel walls after pouring of aluminum under vibration while Pig.5
showsthe longitudinal section of an ingot completely solidified in a vibrat-
ing funnel. A distinct boundary can be observed between the acicular crys-
tal zone and the central crushed grains zone. The grain size depends on the
temperature of the metal during pouring. Higher temperatures ensure complete
melting of the solid phase by the time crystallization of the metal begins.
Higher resistance to hot cracks is attributed to an increase in plasticity

results v-,ere obtained with aluminium. The following mechanism of
grain refinement is suggested. During casting, solid metal forms

on the walls of the pDuring channel. Under the action of the vibr-.
ations and the liquid metal, this is removed and results in solid
fragments being present in the liquid metal poured into the mould.
These become the crystallisation nuclei. The theory was tested by
using a pouring channel at 650 0C for aluminium. At this temper-
ature no solid metal formed and no refinement occurred. Figs. 4a
and,4b s1low that no change in structure occurred at this temper-
ature when vibrations were used. If aluminium wire was fed into
the pouring channel, however, grain refinement occurred (Fig. 4c).
This confirmed the theory that solid fragments of metal were
causing nucleation. In the continuous casting of aluminium and
magnesium alloys, it is therefore necessary to use a cooled pouring
arrangement to obtain grain refinement by vibrations. There are
5 figures and 8 references; 7 Soviet and 1 non-Soviet.

TITLE: Casting thiln-walled, large-sized panel compounds In green sand-clay
molds
PERIODICAL: Liteynoye proizvodstvo, no. 8, 1961, 38 39
TEXT: The casting of thin-walled, large-size panel parts of aluminum and
magnesium alloys ensures a considerable saving 'in the weight of these components
and in time. On the other hand some difficulties must be overcome, in the first
place those encountered in filling the mold with the liquid metal. In the Soviet
Unilon. thin-walled panels are cast by successive crystalliiation or extrusion.
The latter method is applied for A44 (AL4) aluminum alloy sheets 800 x. 1,500 x 2
- 5 mm in size, moreover for A12 and VJ15 (ML5) alloy panels. However, when apply-
ing the method for heat-resistant and high-strength ALS, AL19, T,15 (V15) alloys,
hot cracks are forming. In order to establish the cause of this defect tests
were carried out at the Liteynaya Laboratoriya MVTU im. Baumana (Foundry Labora-
tory MVTU im. Bauman) and it was found tham, panel elements 500 x 800 x 3 4 mm

Casting thin-walled,-large-sized A054/A127
in size could be cast from AL19 and V15 alloys by applying the conventional cast-
ing and using green sand-clay molds. Test panels, 250 x 300 x 2 mm in size were
ca5t using a channel (12 x 12 mm) around the panel which considerably facilitated
the filling of the mold. The removal of air and gases from the mold cavities Is
also important-in this process. When applying 0.3 - o.4 mm thick inserts on the
parting surface of the mold during the assembly, the filling of the mold improved,
the ventilation through the narrow aperture at the parting surface of the mold be-
came more intensive. The circumferential channel.-, the slot-type feeding system
operating over the entire periphery of the casting, a high-capacity slag-chamber
and a riser with a considerable cross section ensure a great intake of the liquid
meta-1 a-rid an instantaneous filling of the mold. Moreover, ribs formed on the
casting also promote a rapid filling of the narrow spaces. The gatte and the ven-
t.-I'lation system based on the above principles for casting 500 x 800 x 3 - 4 mm
panels are shovm. The molding mixture used consists of 55 - 60 % nol (POI) type
Tambovek sand, 4.5 - ':~O % quartz sand and chalk, having a humidity of 6 %ja gas
PermeabIlity of 54 units and a compresssion streng-th of 0.24 - 0.27 kglcW . The
bin,.'er contained 10 % Tambovsk sand and 90 %.burnt sand and had a humidity of
4.5 % and a compression strength of 0.35 kg/cm2. It was found that the applica-

tion of inserts at the parting surface of the mold had an adverse effect on the
accuracy of the panel dimensions. Therefore, to promote ventilation, instead of
using inserts, 1.0 - 1,5 mm wide grooves were out in the parting surface along
the periphery of the casting. This arrangement required a high casting tempera-
ture, (for the AL 4 alloys: 820 - 8300c, for the AL 19 and V15 alloyst 850 - 8600
C). On the other hand the high temperature promoted the formation of (.-tvitLesj(in
some cases the casting split into two parts). This could be eliminatea by con-~
trolling the density of the mixture in the upper part of the mold by changing its
composition and the intensity of ramming. In this way panels can be cast also
from X18H9T (Khl6N9T) steel in dry sand molds. The.mechani 'cal properties of AL4,
V15 and IKh18N9T steel panels meet the standards set. A deterioration of the me-
chanical characteristics could only be observed in AL 19 panels. This was caused
by a lack of heat resistance in the metal. When coating the casting surface with
hexachlorethane, however, the casting temperature of the AL19 alloy sheets could
be reduced from 850 to 7300C. The dimensional accuracy of the castings depended
on the assembling accuracy of the mold and on the stability of the bottom plate.
During assembling the mold showed a deformation of 0.1 - 0.25 mm, while during
transportation (sliocks) the deformation of the thickness of the casting attained
0.4 - 0.5 mm (20 - 30 %). For this reason the application of dry sand core or

T EXT: It has already been established that the effective-
ness of vibration as a j;ieans of grain-reflning of the structure
of castings varies from alloy to alloy. It has been possible in.,,
the case of some materials to determine the optimum conditions

and intensity of vibrations employed. The present author
analyzed the relevant experimental evidence and came to the
.conclusion that,the most likely explanation of the different
response., of, various metals to vibration is best explained
in terms of the theory according to which the grain-refinement
brought abou t by the application of vibration to a molten alloy

during casting is due to the fact that this treatment increases
the number of crystal fragments broken away from the solidifying

theory is correct, then, all other conditions being equal, the
beneficial effect of the vibration should be closely related to
the strength of the crystals of a given alloy near its solidus.
