TITLE: Castings from Brittle Vaterials
PERIODICAL: Liteynoye Proizvodstvo, 1959, Nr 3, pp 16-18 (USSR)
ABSTRACT: For the various branches of the industry it has become
necessary to use materials resistant to high tempera-
turea and chemical influences. Such materials but are
difficult to cut and machine and are not possible to
form by pressure as they do not have any elasticity.
The best method of workability for such materials is
casting. But the main obstacle for Vie latter method
are the appearance of orneks caused by shrinkage and
inner heat pressure of the casting. This dependance
between temperature and pressure of the core material
is represented in one drawing and is well known for
die casting and pressure die casting. it is necessary
that the core material has a greater coefficient of
Card 1/3 heat expansion than the material of the casting.

Castings from Brittle Materials SOV/1 28-501-3-F/3 1
Graphite, carbon, coke, etc., or an other melting ma-
terial are suited as a core material, where the core
material had been previously cast in aluming. In all.
cases preheating of the core material to 2CO or up
to 500 u Celsius is necessary. When casting complicated
shapes, like e.g. pistons, pouring of the COD. 'Dlete
shape is not possible. In such cases the core consists
of several parts. Cracks caused by the pressure ori-
ginating from the cooling-off of the material Rre a
disadvantage too when casting brittle materials, like
e.g. cast iron with a high percentage of chromium,
silicium, diabase, etc. A table is offered listing the
deformations of the materials when cooling-off. Such
cooling-off shall be done slowly and uniformlyt and the
casting should not betaken from the mold too early.
The final solution of the experiments made revealed
that employment of the centrifugal casting wethod (zoo
rpm) with graphite cores preheated from 600 to 850 0
will yield the best results. After pouring the mold

IMT: Pure CaF3 and MgF2 were used as initial materlals for the manufac-
ture of the alloys. The fluorides were melted In crucibles made of electrode
graphite. Gas and electric furnacez assuring heating up to 1,3000C were em-
ployed as melting unita. The'alloy was prepared by provious mixing of powderlike
salts, taken in a given ratio, and subsequent melting of the mixture. Graphite
or graphite-chamotte wore the moot aiiitsiblv matoriala for the nimiufacture of 0
molds in fluoride casting. In all cases the alloy tomperaLure was 1,060 - 1,120
and the temperature of the mold prior to casting was 750 - 8500C. Prior to
casting the mold was dried and roasted at 800 8500C. The filled molde were

containing (in %) 48 MgF2 and 52 CaF2 was investigated. The addition of 2 - 5%
Ni fluoride to the alloy considerably reduces the danger of breakdown of the

TITLE: On the use of pressure crystallization in casting magnesium alloys
PERIODICAL: Izvestiya vyzshikh uchebnykh zavedeniy, Tsvetnaya metallureiya,
110. 3, 1961, 125 - 128
TEXT: Pressure crystallization was proposed by Academician A.A. Bochvar
and Professor A. G. Spasakly as an effective means of eliminating porosity in a~u-
minum alloy castings. This method was as yet not employed in magnesium alloy
castings due to the opinion that these alloys in liquid state were inflammable un-
der high air pressure. The present study was made to reveal the possibility of
using pressure crystallization for 9asting magnesium alloys and to determine the
effect of pressure on the porosity f the castings. The experiments were made with
r1,,7 4 (mI,4) and JIJ7 5 (ML5) alloys. ~The shape and dimension of castings were select,
ed in Euch a manner thEt In one case shrinkage porosity was located In the upper
portion of the casting (Figure 1, a and b) and in the other case over its whole
height (Figure 1,c). The castings were pla~ied in the bottom of the mold, the riser
and the pouring gate were at the top. In all cases the metal was top-poured. The

foundry mold was made of a standard mixture of 5% moisture and with fluorine ad-
mixture. For pressure crystallization the mold was placed In an autoclave. After
pouring, the autoclave cover was closed and compreszed air was supplied. To pre-
vent ignition, sulfur powder was placed around the air gate and the riser. The
mold was hEld in the autoclave for 10 - 15 minutes, then specimens werp cut out and
their porosity was determined from the density by double weighing in air and gly-
cer1n, and by weighing and measuring. Castings were manufactured by crystalliza-
tion under conventional conditions and under pressure of 1.5, 3, 4 and 5 atg. The
alloy temperature was 7600C. It was found that the density of the specimens in-
creased with higher pressure. The distribution of porosity oVer thr., height was
studied on specimens shown in figure 1c. cast into twc molds. In one mold crystal-
lization proceeded under conventional conditions, in the other one under 1.5, 3 and
5 atg pressure. ML5 alloys were cast at 690 and 8000C. It was found that in all
cases but one a higher dennity was observed in preasurp crystallized castings. The
dense portion of a conventionally crystallized casting was about 15% of its total
height, that of a pressure crystallized casting 30 - 40%. The experiments perform-
ed lead to the following conclusions: Pressure crystallization, employed in alu-
minum alloy casting, can also be recommended for magnesium alloy casting. For this
purpose risers having a sufficient volume should be placed above the compact pams

of the ca2ting. Casting hhould be performed in an autoclave by crystallization
under 3 - 5 atg. pressure. The alloys must be heated to 760 - 8000C, to maintain
one portion ofthe alloy in prolonged liquid state so that the shrinkage pores be
fully soaked under the effect of high pressure. Magnesium alloys in liquid state
are not influrimable under high pressure. To prevent acciddntal i&mition it is 'suf-
flci~_,nt to pour some sulfur powder around the ,-riser and the air gate. This article

TITLE, Pemoving films from metals by filtration
PERIODICAL~~ Liteynoye proizvodstvo, no. 12, 1961, 22 - 24
TEXT ~ The authors point out that quite a number of alloys during melting
and pouring are considerably contaminated with oxide films which reduce their
technological and mechanical properties tnd the quality of components. They
enumerate a number of metal purification processes and report on tests which
were carried out to remove films from aluminum alloys by filtration. These
tests were carried out during the semi-continuous casting of ingots of the A16
(D16) andAK6 (AK6) alloys by A.G. Spasskiy, M.V. Pikunov and AN. Kurdyu;nov.
Prior to the casting process, filtration was studied by simulating metal fil-
tratlon with water with pieces of paper representing the films. Lumps of
srusned magnesite bricks were used as filtering agent. The filtration results
showed that a lump filter of 50 mm thickness holds back 50 - 70% of particles 1
x I mm in size, while a filter of 100 mm thickness detains 90 - 95% of such
particles. During tho% filtration of the D16 alloy, melted in a graphite cruci-

ble at 7503C, the lump filter was placed in the spout, which was preheated to
7000C, 5 - 7 ingots 50 mm IM diameter and 150 mm high were cast in succession.
,Th#- number 7~f fi3ms and their total area were counted on the fracture. Three

trick of 5 - 10 lump size and with filtration through lumps of a 'Telt

~-d yielded good results the metal purity was still Insufficient, which cculd be
explained by the fact that the metal, after passing through the filter, ran in
ar open flow, thus oxidizing again and contaminating with film. Another test
series was carried out under industrial conditions with the partlcipattcn of P.
Ye. K'~,.cdakov, V.V. Solov'yeva, M.G. Kasheyev and I. I. Ger"yev, wh~-re 'th'e f.11-

al affer filtration. Under these conditions the average contaminatIon amcunrtd
to 1.7% without filtration and 0.24% with filtraticn. The results obtained
make it possible to conclude that filtration through lump filters in the semi-
continuous casting of aluminum alloys improves the metal purity considerably as
regards film. The filter should be placed in the distributing funnel., while
crushed mabnesite brick, either with or without flux impregnation, and fluoride
al-11-cys can be used as filtering ma-,-erlal. Magnesite and fluoride allf'ys are
heavier than aluminum and there is no chemical reaction up to 1,0000C' Further
tests with lump filters carried out during pressure casting by M.V. Pikunov.
Ye.Ya. Lebedev and A.G. Spasskly showed the applicability of this filtraticri
method also for pres3ure casting. Various Al-alloys -AJ19B (ALgV),AJ13q (AL311"N

TITLE: The effect of vacuum treatment on casting properties of,4jl 10 (ALIO)
alloy
PERIODICAL: Izvestlya vysshikh uchebnykh zavedeniy, Tsvetnaya metallurgiya,
no. 3, 1962, 147 - 153
TEXT; An Investigation was.made for the purpose of gathering data on the
effect of vacuum-treatment upon the casting properties of Al alloys and to reveal
the expediency of using such a method for ALIO alloys. Tile following factors
were studied In particular: the effect of the vacuum rarefaction, holding time
and temperature of the melt during vacuum-treatment upon gas-saturation, porcsity
of castings, volume shrinkage, the voluige of an open shrinkage-cavity, crack sen-
sitivity of the alloy during inhibited shrinkage, fluidity and don3ity. Castings
were produced under conventional conditlona and with vacuum treatment on a unit
shown in Figure 1 at 10, 100, 200 and 300 mm Hg residual pressure in the auto-
clave. It was found that vacuum treatment of liquid alloy ALIO changed consider-

ably its casting properties at relatively low pressure (10 mm Hg). Vacuum treat-
ment promotes the elimination of dissolved gas from the melt. Practically full
elimination of the gas is assured by holding the melt In the autoclave for 25 -
30 minutes at 750 - 8000C and 10 mm HS residual pressure. Porosity of vacuum-
treated castings is below that of conventional specimens. Density increases
with higher rarefaction and extended holding time In a vacuum. Volumetric
shrinkage of vacuum-treated castings exceeds that of conventional ones. With a
greater rarefaction in the vacuum, the shrinkage increases to 9.8 - 10.36% at
10 mm Hg residual pressure. Extended holding time at constant rarefaction and
temperature Increases volume shrinkage, whose maximum is observed at 15 - 20
minute holding time. The volume of an open shrinkage cavity incrCaSe.'3,with
vacuum treatment. Crack sensitivity of AL10 alloy during Inhibited shrinkaze
increases with greater rarefaction; it is almost twice as high as that of non-
treated material; this is explained by higher volume shrinkage and reduced gas
saturation and porosity of vacuum-treated samples. Fluidity is only affected
by vacuum treatment at lower temperatures. It is greater for a vacuum-treated
specimen. The,expediency of using vacuum treatment should be established for
each particulAr'case by taking Into account the increase in orack-Bensitivity

during inhibited shrinkage. In the case of cQmpnct cantinga, whor, there is no
particular shrinkage vesistance from the mold, gaseous porosity will be eliminated
anddensity will increase on account of large-volume concentrated shrinkage cavi-
ties. On the other hand, when shrinkage Is inhibited by the mold or the core,
vacuum-treatment will increase the amount of reject:s due to cracks. There are
3 figures and 2 tables.

FERIODICALt Liteynoye proizvodstvo, no. 4, 1962, 4 - 5
V-'.T: The authors mention the fact that magnesium-alloy castings rather
o,c,en show a considerable porosity. The industrial Mil 4 (mrh) and [AJ1 5(ML5)
alloys possess a great crystallization temperature range of 2100 and 1570C
respectively. The volume of micropores may be considered insignificant, it is
In the range of 0.75 to 1% of the total casting volume, but the tensile strength
of specimens of 0.75% microporosity decreases already by a factor of 2, "Inveati-
gations were carried out to study the possibility of applying pressurized
crystallization in casting the ML4 and ML5 :magnesium alloys, and to find out
the effect of pressure on the casting porosity. The alloys were produced from
fresh metal and master alloys and were cast in ingot molds. To prevent the feed-
ing of the casting from the riser, the gate dimennions were chosen in such a
way that the metal in it crystallized in the first place. For pressurized crys-
tallization the mold was placed in an autoclavo whose cover was closed after

the metal was poured into the green mold. Compressed air was supplied Into the
autoclave and the mold was held under pressure for 10 - 15 min. The porosity
of the pressnrized castings was determined by comparing them to Opecimens cast
in the conventional way. The results proved that pressurized cr-ystallization
of magnesium-alloya increased their density, and the higher the pressure, the
lower will be the porosity. The best results were obtained at pressures of 3 - 5
atm. Moreover, a comparison of -the porosity of specimens poured at 690 and 8000C
respectively revealed that the pressure affect was higher when pouring was effect-
ed at.elevated temperatures. The authors conclude by stating that pressurized
crystallization, which has been successfully employed in the casting of Al-alloA
will result in a higher density and lower porosity of magnesium castings, the
optimum pressure magnitude being 3 - 5 atm, while the pouring temperature should X
not be lower than 760 - 8WOC. 7here are 4 figures.

of the AJI 4 (AW_ alloy
PERIODICAL: 'Liteynoye proizvodstvo, no, 3, 196-3, 111 - 42,
T _Ur , To avoid the formation of an acicular structure, the widely used
AL4 alloy has to be modified by sodium salts. During t1i Inoculiation, however,
the alloy adsorbs hydrogen resulting in a considerable poron1ty of tic me"al.
,rests were carried out to establish a suitable refining method for this alloy,
which would not weaken or shorten the effect of modification, by subjecting the
alloy to vacuum treatment.- In the tests the AL4 alloy, containing, heesides Al,
9.91, Si, 0.25% Mg, 0.5% Mn and 0.41% Fe, war, used. The degrf.-c of mod1fication
was assessed by the grain size of silicon In the eutectic (the bigger the grain
size, the weaker the effect of inoculation). For modification the fluor and
chlorine salts of sodium were used in a 2 : 1 ratio, amountir6g, to 2% of the al-
loy quantity; samples were processed at teciperatures between 750 and 810'C, and

surface and microatructure of the -%pecimens showed that the effect of' sodium in-
oculation can be maintained for tho longest time (20 - 30 min) and a dense metal
