TITLE: On the Pressing of Metal Powders (0 pressovanii
metallicheskikh poroshkov)
PERIODICAL:Vestnik mashinostroyeniya, 1959, Nr 5, PP 53-56 (USSR)
ABSTRACT: Investigations are rep6rted on the behaviour of metal
powders during pressing. To examine the effect of the
duration of pressure application, iron powder, obtained
by the reduction of scale, and tungsten powder of
4.2 microns mean particle size were pressed in a
cylindrical steel mould at pressures of 2, 4 and
6 tons/cm2. The duration was varied between
instantaneous application and 3 minutes. Briquettes
so compressed were sintered in a hydrogen atmosphere
at 1000-11500C for iron and 2100% for tungsten
during I hour. The density of iron pressings izw-reased
with pressure and duration, e.g. from 4.30 g/cm3 to 2
5.65 g/cm3 between 2 and 6 tons/cm2 and from 5.65 9/cm
to 6.74 g/cM2 between instantaneous and 3 minute
durations, both at 6 tons/cm2. The density 3drops
Card 1/4 after sintering e.g. from 6.74 to 5 .83 g/cm . The

On the Pressing of Metal Powders
SOV/122-59-5-18/32
effects of pressure and duration are similar in
principle for tungsten pressings but sintering 2
increases the density, e.g. from 11.52 to 14.20 g/cm
when sintered after pressing for 3 minutes at
6 tons/cM2. The "spring-back" of pressings was
examined by measuring the height of a 12.3 mm diameter
cylinder before and after the release of pressure.
A range of particle sizes and pressures was examined
with tungsten, tungsten carbide, iron, copper and
aluminium powders. The values of spring-back plotted
over the pressure (Fig 1) show a moderate rise but also
a drop beyond 6 tons_/cm2 in the case of tungsten carbide.
Values range between 1.5 and 2.8%. Tungsten and copper
powder pressings were made in a cylindrical mould of
12 mm diameter, followed by pulverising the pressing
and repeated pressing. Up to 3 repetitions were
carried out. The density goes on increasing from
pressing to pressing in copper, provided the subsequent
Card 2/4 pressure is at least equal to the preceding. The effect

On the Pressing of Metal Powders
SOV/122-59-5-18/32
is much smaller in tungsten powder pressings.
Following H. Unckel (Arch. Eisenhtttenvesen,~
18, 161, 1945) the pressure distribution in the mould
was examined with a special mould incorporating soft
copper rings, into which 4 steel balls are pressed
(Fig 2). The sub-division between the pressure on
the mould bottom and the friction force on the mould
walls can be found. The present tests were mainly
concerned with means of reducing the wall friction
comp-r--'. Copper powder obtained by the reduction
of Co.. oxide with hydrogen to a mean particle size
of 2-.> microns, iron powder of 2-3 microns and tungsten
powder obtained by the reduction of tungsten anhydride
were tested with a lubricant consisting of 3a 4%
solution of paraffin wax in petrol (150 cm of lubricant
per 100 g of powder). Pressures between 0.4 and 2.5
tons/cm2 were tried. The friction force component
increases with rising pressure without lubricant but
decreases with lubricant. Seizure of the mould walls
Card 3/4 by the powder may be the explanation. The increase of

On the Pressing of Metal Powders
SOV/122-59-5-18/32
friction force with pressure in iron powder is
pronounced. The residual porosity falls with
increasing pressure, particularly in copper (by a
factor of 2 w4thout lubricant and 3 with lubricant).
The strength and hardness in copper and tungsten are
lower with lubricant than without, while in iron they
are equal either with lubricant or without. There are
2 figures, 5 tables and 3 references, 2 of which are
Soviet and I German.

ABSTRACT: The present paper gives a survey on the kinds of production
as well as on the various types of finished products of pow=
der metallurgy. It is mainly foreign processes and finished
products which are mentioned. In the production of powder
the authors point out the importance of structural charac=
teris,tics as well as of the size of particles, with physi=
co-chemical and mechanical methods of production being men=
tioned. A table of the characteristic features of metal
powders obtained by different methods is given. The pres=
sing and sintering of metal powder or powder mixtures re=
spectively are carried out either simultaneously or by
soaking the DOrOUS pressed article in liquid metal, or
Card 1/4 also by means of a pressing into bands and other forms

with plastifying additions or resins. An aftertreatment
of the sintered finished product by thermal or chemico-
thermal treatment can take nlace to raise the quality of
the article, In the detaile-d description of povider i:ietallur=
gical filters among others some production methods are .-.en=
tioned with the pictures and the individual data of sin3le
filters produced of iron granulate mixed with graphite- or
bronze granulate, respectively, being mentioned. The Proper=
ties of the filter as well as the filtration effect de,.~r-n=
ding on various properties, and also the possibilities of
arranging the filters are described. "Zinterit" is mentio=
ned for the solidification of packings as well as a ma=
terial developed analogously to it by V. P. Makhayev
(Ref. 19) which is obtained in pressed bands from iron
sponge mixed with 18% of petroleum bitumen. In the descrip=
tion of porous electrodes for electro-chemical processes
the investigations by L! L. Kuzlmin and V. S. Poroykova

ABSTRACT: The authcre emphasize the necessity of appointing
in enterprises special workers who constantly hand-
le matters relating to the organization of produc-
tion. This idea has already been realized in many
installations, but to a full extent it will be car-
ried out only when the vuzes will train engineers of
a corresponding specialty. The authors believe that
the engineer-economists, presently trained by the
L?vov Polytechnical Institute, could successfully fill
the position of engineers supervising the organiza-
tion of production providing their knowledge on mat-
ters of technology and organization of production,
is somewhat increased.

TEXT: The first test model of the ionophone, developed by the Leningrad
Elec trotechnical Institute of Communication, is described as well as the princi-
ple of the converter and a detailed basic circuit of the h-f generator, the main
power supply element of the converter. It is pointed out that in its present
form the ionophone differs considerably from the initial model propomed by Z.
Kleyn and can be considered as a sufficiently promising type of an inertialess
electroacoustic converter. The device can be tuned in such a way that noises are
practically not perceived. Amplitude and frequency characteristics of the lono-
phone are given. It is possible to use the ionophone in 2-band acoustic units
for reproducing the upper audio frequency sub-band and in single-band acousti,-

ABSTRACT: High thermal stresses arise in gas turbine blades when the gas Cempera-
,ture changes sharply. These stresses may even exceed the yield point of the blade
material at these temperatures. The present paper investigates the elastic-plastic
stressed condition of a stator blade with a temperature tield which was st,adied ex-
,2erimentally for various transient speeds of the turbine, including starting. The
~bighest temperature gradient in the blade was shown to be 400C and over. On the

~;~basis of: experinental.dita and by means of a hydraulic integrator, the problem was
solved for variable heat transmission, allowing the author to estimate the condi-
;-tions-of heat exchange to the blade surface and to determine the temperature field
the -th6imgl-,.stresbe-a-were:-calculated -with-
,!'but- taking irito--zecount :plastic deformation- of the blade. It -was found that the
.stresses increased rapidly and reached a maximum after 30-40 seconds. At the lead-
ing and trailing edges, as well as along the entire convex surface of the blade,
'compression stress arises, while tension stress appears at the middle and concave
~Par
i t of the blade. This complicated stress distribution is caused by thermal
,elastic bending of the blade, considering that the blade preserves elasticity dur-
ing the entire proyess. The tests showed that there was actually plastic deforma-
~tionof the blade.N-tTherefore, an elastic-plastic solution had to be found. Cal-
,culatiors are given for starting of the turbine, when the highest stresses appear.
';Analysis of the results of elastic-plastic stress calculations indicates that very
thigh deformations arise at the leading edge of the blade, resulting in some residual
:tensile stresses. This leads to thermal fatigue v-hen the gas temperature reaches
:1200C. Orig. art. has: 4 figures and 7 formulas.
