ABSTRACT: A study of high energy muons, using the horizontal flux zenith angles af.00
of cosmic rays at sea level was made and an ionization calorimeter developed for this
purpose is described. Such a study is feasible because the horizontal flux at large
zenith angles 0 consist almost exclusively of muons and the intensity of muons for
energies >1011 ev increases with 0. The apparatus uses muon flux to study high ener-
&y muon interactions with inatter and measures the characteristics of the horizontal
muon flux to determine the angular and energy distributions. The Ionization calori.-
meter enables one to study both of these areas by observing the showers produced by
the muons due primarily to bremsstrahlung and nuclear interactions. It aetects muon3

of 150 ionization chambers an7anged in six rows, forming a coordinate set for dete,,--
mining the angle made of a shower. A layer of iron 9 cm thick is placed between each
row with a total weight >40 tons. Each chamber is made from a section of waveguide
J.10 K 54 mm and 3 m long with an electrode $ mm in diameter at t1200 volts, filled
with argon at a pressure of 5 atm. A block diagram of the major component is sholni.
The pulse from each chamber iii amplified and then stored on capacitors in the memo:c-y
section which is successively probed by a mechanical commutator. The commutator sIg-
nal is photographed using an A-700 loop oscilloscope. The event selection and switch
ing of the detector take placis in the control block. The registration block recorils

ABSTRACT: The non-electromagnetic interactions of superhigh-energy muons
(E 1011 ev) we're record-ad at an Installation for the study of cascade sho-
wers.produced by cosmic radiation muons impinging at large Eenith angles (cf.
Borog et al, Izvestiya Akademti Nauk SSSR, Seriya Fizicheskays, 30, 10, 1669,
1966). The only knourn process which could give rise to the non-electromagnetic
cascade showers recorded was that of nuclear Interaction of muons. A comparison
of the spectra of nuclear and electromagnetic-showers made it possible to eva-
luate the cross-section a'(j4 of the photonuclear process at E 10 ev.

ABSTRACT. A 60-kw ionic f:requency converter for electrothermal installations
developed by LH imeni M. I. Kalinin is described, Its output frequency is
2,500-Z,800 cps. Its scheme has an implicit DC circuit. Six TR1-15/15
thyratrons are connected on their cathode side in three groups of two and
connected to the three-phase rectifying transformer; on their an'ode side, they
are arranged in two groups of three each and connected to the terminals of a
single-phase inverter transformer. A smoothing choke coi-I is connected

between the neutrals of both transformers. An oscillatory circuit formed by
the furnace inductor and the phase-control capacitor serves as a load for the
converter The grid-control circuit of the inverter is fed from the converter
output via an RC phase slufter The self-control feature secures the followin.g*
(1) an automatic frequency control as the circuit parameters chaiige in -the
course of metal heating, and (2) short-circuit protection upon collapse of
inverter oscillations. However. an additional special device to open the valves
for starting is required. When the power is adjusted by the phase shifter, the
inverter -transformer ratio is changed -and the f iring -point -controlling
capacitors are switched simultaneously. In the schemes with an explicit DC
circuit, the rectifier grid control can be used advantageously. Experimental
regulating and load characteristics of the converter are presented. It is pointed
out that in schemes with higher frequencies, it is expedient to prolong the
recovery time for the valves. Another solution is to use a converter with a

single-phase inverters whose inverter -transformer secondaries are connected

ABSTRACT: High-freqUency electro-thermal installations with valve
generators for induction-heating are widely used. A mass-
produced equipment; has lacked anode voltage stabilisation and
needs careful screening to reduce radio interference. A new
series og equipment has been developed that operates at a
frequency of ?0 kc/s, so that both the fundamental and the
second harmonic are outside the standard frequency range for
radio interference. This new equipment, type sln3,-6?, employs
a stabilised anode-controller rectifier. The main technical
data are given with a full-circuit diagram in Fig.1 and the
main components of the circuit are described: the rated output
is 60 kW. The principles of the grid control system are des-,
cribed. A change of the grid voltage varies the firing angle of
the valve. The main advantage of the circuit is its simplicity
and although the accuracy of stabilisation is less than that
Cardl/2of existing circults, it is nevertheless adequate. The equipment

A High-frequency Electro-thermal Installation of a dew Series
includes protectio.n against short-circuit, crerload and under-
voltage. A general view of the equipment is given in Fig.2.
It is housed in a number of separate cubicles, whose contents
are described..
A wide range of tests was made on the equipment; its charactor-
istics are given in kig.3. These curves show that the genera.-
tor can easily be adjusted to give the best operating conditions
on the most varied loads. The oscillatory power ranges from
40 - 60 kW and the efficiency of the generator valve is 72 - ''?8%.
The power-factor depends on the ignition angles of the thyratron
and ranges from 0.'72 - 0.93. During the tests careful measure-
ments were made of radio-interference with the results plotted
in Fig.4, v.,hich sh:)ws that interference is worst at light-loads
but is still within the specified limits even when the cubicle.,
doors are open.
There are 4 figures, and 7 Russian references.

ABSTRACT: The USSM industry at present -pr6duces. large thyratrons of -the
TRI-115/15-type wLthin a sufficiently short'time for the re-'estabMbaent
of the controllability of the grid. rnvestigations show that they
operate with irufficient reliability in frequency converters of
,W2500 oyales. The wiring diagrams of these converters are
given. As the basic wiring diagrams of similar converters have
&Iready been dealt with by the papers of references-i and 2, the
a,uxiliary oii(niits are in this case mainly investigated. Figure I
shows the wirJmg of an ion frequency converter of 50/2500 -dyoles &ad

been used for the melting of metal since July 11057 at the

The rectifier of this converter is a -three-phase single-eyole
rectifier withi 3 valves and one converter. The inverter is constrwted
as a single-phase single-oycle inverter with 2 valves and 1
oonvertar. It is shown that an inverter for 25M cycles embodied
within -the th3Tatron mentioned must necessarily be a single-ayole
inverter. Reguilation of the initial output Pk is brought about by
variation 1) of the capacity of the capacitor G~, 2)~ of the phase
shift angle 4f between the grid- and anode voltages of the
thyratrons'of the inverter group, and 3) of the economy transformer
coupling of ths load circuit Lkak with the inverter-transformer.
The experimentally obtained characteristics of the converter
corresponding to these three kinds of regulation are shown by
figure 2.2he disadvantage of the'lo and 2. method is the stopped
regulatIon. Apart from the circuit shown by figure 1, where one
valve group is used only for rectification and the other only for
invertLag the current, also ionic converters with a direct current
element (Refs 1, 2) may be used in slectrothermal installations. In'
this case thei same valves are used for rectification and inversion.

ABSTRACT: Any titanilm compound possessing electronic
conductivity can 'be used as soluble anode. The
authors used titanium nitrides and carbides and
hydrogen-containing, oxygenous and inter-netallic
compo-ands of titanium, as well as titanium-base alloys
for their experiments. These were carried out in a large
laboratory plant with a maximum current supply of 1000 A_
The electrolysis cell is shown diagrwiamat ic ally in the
f igure, P 57 (1 - bath; 2 - lid; 3 - cell; 4 - anode lead;
'j
5 - cathode lead; 6 - syphon). The entire appa~ratus was
made of stainless steel. Compact anades, made by
powder metallurgical methods were used, T~iese were
fixed into position and connected up and a mixture of

Oxi the Production of Titanium by Electrolysis of Molten Salts
By Using Soluble Anodes
Any residual moisture and occluded gases were removed
by melting. A second (electrolytic) purification was
carried out, in the course of which the electrolyte
was saturated with titanium by means of an auxiliary
cathode, and then electrolysis with a working c&-L-jhod4e
was carried out. All operations were carried 011-vt il-I CI
stream of dry, pur-4.fied argon. All the experiments
were performed at a temperature of 7600C and in each
case the quantity of electricity was the same
(1500.k hours). The following were analyzed: the
cathode powder obtained on working with the aux-ciliary
cathode; three layers of the cathode deposit (intern,__,.I.
middle and outer); th-Tee layers of anode slimei the
electrolyte and the removed products. The resuits of
experknents with Ti-Fe, Ti-Al, Ti-Si and Ti-Nb alloys
are shown in Table 1. At present the authors are
engaged on -the study of binary alloys of ~_'Ii and Ni,
Ga and similar metals, and Mn. Preliminary

analogous to that of Fe; Ga and like metals dissolve
off the anode preferentially to titanium but are not
deposited at the cathode. If lin is -present in the
anode, the latter is soluble only if its oxygen conten-~.
is ex.tremely small. Dean's findings regarding the
sharp drop in the solubility of titanium in the
presence of oxygen have beon confirmed. The results
obtained for anode material containing 0.3% 02 are
shovni in Tabl-B 2. Preliminary experiments with
multi-constituent alloys have led to the conclusion
that most metals change the anodic solution process of
titanium, as known for binary alloys, verv lit"le.
This should enable electrolytic refining of -Drelimir,arily

TXXTs Shells"(85 and 100 mmjin diameter, 150 to 200 mn2 high),
prepared by powder metallurxyVtechnique from technical grade
titanium IMP1, were extruded on a 600 t vertical extrusion press,
equipped with die and mandrel made of steel 3KhV8. The, shells
were pre-heated to 860 to 1050% by induction heating (5 to 10 min),
the temperature of the container being 200 to 250*C. A, mixture
of graphite and machine oil was used as a lubricant. The
extrusion pressure did not exceed 180 atm when the extrusion
temperature was 80001', and decre'ased to below 150 atm for shells
pre-heated to 9500C. The extrusion speed of 8 m/sec was usedo
the tubes obtained biting 32 to 50 mm in diameter with the wall
thickness varying between 2.5 and 7.5 mm. Irrespective of the
extrusion temperature employed, the extruded tubes had
longitudinal scratches on both outside and inside surfaces.

Manufacture of Titanium Tubes from Sintered Material by
Extrusion and Rolling
The surface finish of tubes extruded at temperatures above
950% was extremely bad. The condition of the container and
particularly of the mandrel, after one operation only, was also
very bad, owing to titanium adhering to their surfaces, which was
also the cause of the longitudinal scratches on the extruded
tubes. Somewhat better results were obtained when steel RIB was
used as the materi&l of the container lining and mandrel, but even
then these parts haid to be scrapped after each operation. Several
attempts were made to improve the surface finish of the tubes by
applying diffevent lub3r!.cants; the best results were obtained with
a mixture containing 4 parts of sodium chloride and 1 part of
fluorspar which, however, failed to prevent the formation of the
longitudinal scratches. The extruded tubes (measuring 32 x 3,
39 x 2.5, 41 x 3 and 50 x 7.5 mm) had the following propertiess
U.T.S. = 70 kg/mm2; elongation, b, = 21%; reduction of
area, T 0 = 29%; Rockwell hardness, R. = 26. The material of
the extruded tubes was markedly anisotropic in respect of its

corresponding figures for specimens tested in the transverse
direction were 120.8 kg/'mm2, 2.5% and 6.3%. owing to the
lack of suitable equipment, the surfaces of the extruded tubes
were not improved before rolling. The slight curvature of the
tubes was removed by hammering with wooden mallets at 800*C.
Both ends of each tube with bad extrusion defects were cut off
and the outside and inside surfaces were lubricated with a mixture
of 60% emulsol and 40% graphite, no lubricant having been fed to
the mandrel. The rolling operation was carried out on a tube
rolling mill of the Rockwright type. To avoid cracking during
rolling, the ends of each tube were machined to produce a taper
at least 60 to 80 mm long. After the first rolling operation,
during which the temperature of the tubes rose to 100*C. the
tubes were annealed at TDOOC by resistance heating, the heating
time varying between 20 and 40 see. The ends of the tubes were
then cut off again and taperedv after which the second rolling

operation was carried out. The degree of deformation attained
in the first rolling operation, without causing fracture of the
tube, was 34.2%. After the intermediate annealing operation,
56-7% reduction per pass could be attained. The tubes of the
following dimensions (mm) were produced by this method: 22x 1,22x125,

between 1500 and 6000 mm. While the results obtain6d showed
that the technique istudied had some possibilities, means of
preventing adhesion of titanium on the extrusion tools will have

TEXTs The present paper gives results of a systematic study of
the process of titanium strip production, carried out in 1957 to
1959~ The powder used had a specific weight of o.65 -- 0.80 S/cm3
and not less than 90% of the particles were 10p Impurities did
not exceeds 0.25% 02v 0-01% H2, 0.08Y* N29 0.50% Fe+ Ni,
0.08% sij 0.05% C. A diagram of the method of production is
shown in Fig.l. The thickness of the strip produced was found to
be directly proportional to the specific weight of the powder and
did not depend on the particle size. The maximum thickness
produced was 1.20 mm on rolls of 120 mm diameter. With increase
in roll diameter, the thickness of the strip could be increased.
Fig-3 shows the effect of the speed of rolling on the thickness of
the strip (Curve 1), the power per width of the strip in kW/cm
(Curve 2). the energy consumption (Curve 3) and the productivity

Production of Titanium Strip by Rolling Powders
in diameter and strip 120 mm wide, the production is 44 Rg/hour
or approximately 250 tons/year. With 500 mm wide strip it is
approximately 1000 tons/year. The porosity can be varitid from 23
to 57% by varying the distance between the rollers. The strip
produced has sufficient strength for transferring to the sintering
furnace. With increase in sintering temperature from 850 to
1150*C, the strength and 6plasticity of the 5trip increase (Table 2).
After 30 minutes at 1.400 C, grain growth was noted. At 950'C?
increasing the time of sintering causes the number of pores to
devrease and ihe grain boundaries to become more distinct. After
two hours, grain grow-th oc;r-urs. ~qPld rolling t.be strip produced
with 20 to 80% degree of reduction presents n-o difficulty. With
increase in reduction, the mechanical properties increase., The
properties of strip sintered at 850 to 1150%, cold rolled and heat
treated for 30 minutes at 700*C, are low. By repeating the cycle
of the low temperature sinter and cold rolling, better properties
similar to those of the control strip could be obtained (Table 4).
Some trouble was encountered with the brittleness of the strip.
This was associated with hydrogen impurity and could be removed

range for the.binary TI-Fe, Ti-Cr, Ti;--Co, Ti-Mo, Ti-V, Ti-.NL'b and
Ti-Ta alloys containing 2-100,10 of the alloying elements, the consti-,
tution of these alloys was determined by metallographic and X-ray
diffraction analyzis,and the hardness of the alloys after various
heat-treatments was measured. -Experimental test pieces were
prepared by powder metallurc.,Py. No deflection points were obscrved
on the dilatometric curves in the case of specimens annealed by
0
heating to 800 or 900 C with slow cooling; the slope of the
curves was constant, indicating that the coefficients of therr.'al
expansion of the alloys studied in the annealed condition werc
constant. The hardness of the annealed alloys was either- equcl

Central Institute of Sciqmtific Research in Ferrous Metallurgy has been developing
the first iudustrial-scale mill for the rolling of metal powlers and has al-
ready used it to roll shcets 5-7 mm thick and as much as 630 imi wide from pow--
ders of iron, electrolytic titanium, aluminum and certain alloys obtained by
combined reduction (nichrome, stainless steel). The powder-metallurgical method
of the production of semifinished products is'economically worthwhile, since
the sintered billets do not require cold working. True, in sonte cases the pro-
duction cost is higher, owing to the high cost of the metal pawders, but once the
scale of production is sufficiently large this factor can be considerably re-
duced. The methods developed for producing strip and sheet metal by the direct.
rolling of powders assure a high percentage of acceptable output and zakes pos-
sible the complete mechanization and automation of the production process. For
exanple, the wastes in the production of titanium pipe by extrusion reach 50%
of 'the weight of metal, Vhereas.when this pipe is produced by the powder-metal.-
lurgical pressing and sinteriug method the wastes are only 5%. The homogeneity

ABSTRACT: The powders of j "'
L1, LTj ~jj Kbt and other metals with a low content of
impurities can be successfiilly produced by reducing their oxides only if an
active reducing eigent with a high lose of the free energy of oxide formation is i--
used (e.ge, Ca, Kn, or Ks)o Such an agent should not form any alloyt; or chemical
compounds with the reduced metal, and the reaction products (CaO, ftO, ate.)
vhould be easily separated by some known technique of mechanical or chemical con-
centration. Theso requirements are. completely met by metallic calcitm. The free

ACCESSION NR: AT5022890
energy-of fornation-and:h"t~oflfozmation of the ozL4,t of Ca (C&O) are higher. than
for the other suitable 'reducing agents known. Since, however, the uve of metRIlic I
Ca for this purpose presents certain practical difficulties, as well. to the danger
of ignition and explosion, calciumhydride CaH2 is used instead. Thein the re-
duction of the oxides of metals follows the reaction:
:RH,_Me+ce0+Hz+Q-_k_____fe___j_
+ jou, a kcal]
i
As experiments heive shcwn, it is expedient to prepare the charge partly from
metal powders andl partly from metal oxides. This serves to reduce the thermal ef-
fect of the reaction am the expenditure of expensive CaH . Thus, for example,
the powder of 11118MItainless steel (72% Fe, 18% Cr, R Ni, 1% Ti) is lire-
pared by reaci_inj_,,7k_t_W,CaH2a mixture of Fe powder (base), ferric oxide, nickel

for increasing size. Shrinkage during pressing takes place uniformly over the entire
height of the fitting. The particles of powder do not move along the rubber shell ands
consequently there is no friction. This gives the finished part identical density
(porosity) at all points. It is shown that the porosity of the finished product is a
.function of the granulometric composition of the powder, the hydrostatic pressure, th'
!quantity of binder used and sintcring conditions. The article vas presented ibr pub-

ABSTRACT: 3Eh2V8 steel do well as copper alloys, which are currently used as the materials
,of molds for pressure die casting of steel,, are of insufficient strength, and this hampers the

.Videspread int -jof pressure die casting. In this connection, the authors experimented
of TsSDM ~;iolybienum, obtained by po),
with the use - ~~r-metallurgical methodsASintered
blanks weighing tip to 16 kg, measuring 90 min in diameter and 180 in height, were drop--forged
into 40xll5YJ60 mm sheet bars (at temperatures beginning with 1600-1650'C and ending iv: 'th
ROO-1200-C). Molds made of sint6red and deformed Me were heated at various temperatures,

thus establishing that the danger of the breakage or hot crackinj~ of the molds can be JUITtinated, 1
if they are heated to 300*C when used in the pres re die casting, of 20 and IKhl8N9Ttsteels.
~t
Their service life is longer than that of 3Kh2V8 eel: they retain a satisfactory shape "~er
beirg re-used 540 times, whereas molds made of 3Rh2V8 steel can be satisfactorily re-used
only 240 times. Thus, the use of molybdenum molds may markedly reduce casting cost.
