ABSTIUCT: It is stated that,so far,methods for determining the
oxygen content in aluminium bronze have not been described.
In the Metal Research InstituteofPanenskd Br"eiany two
methods are applied. In the first instance chemical
determination, which is easier to ixtroduce into the
manufacturing process, in the second instance the
vacuum extraction method is applied. The execution of
both methods is described. For some specimens both
methods were applied and the results are compared in
Table 5. The results obtained by the brom-methanol
method, so far used exclusively for determining oxygen
in aliminium, is in good agreement with the results
obtained by vacuum extraction. The smelting in vacuum is
affected at 1.650'JC directly in a graphite crucible without

of the main carbide framework which could
be produced by a somewhat different method of crystalliza-
tion and which would quite definitely manifest itself in
the final properties of the cemented carbide components.
Therefore, the arrived at conclusions should be verified
on aIntered carbides produced by ordinary methods using
sintoring media which proved most suitable in the here
described tests. In these, the authors investigated
the properties of an "artificial sintering substance",
i.e. a Need cobalt alloy, the composition of which was
Card 1/3 chosen to correspond with the ideas of the author on the,

CZECH/34-59-9-8/29
Contribution to the Study of the Siritering Phase of Cemented
Carbide&
desired composition of the sintering phase in sintered
carbidsis currently used in machining and fabricating.
Such tests can also be applied for studying the effect
of certain additional carbide admixtures, which have a
pr--o-n-o-u--n-cod-influenco-on-the-proptrties of -the--sintering------
phase. As examples, the authors describe the application
of this method to the study of crystallization of Co-WC-
systems-with various CO/VC ratios (50, 33, 45% WC) and
Co-WC systems, some containing additionally TiC, TaC,
Cr C2 and VC. On the basis of the obtained results,
thl authors conclude that the composition and the
crystallization of the sintering phase cannot be allowed
to be governed by random manufacturing conditions and that
it in necessary to study systematically the phenomena
occurring in these three ranges, which are diagrammatically
outlined in Fig-10, P 789- This is a sketch-reprtsenting
the crystallization of the sintering phase in the cavity
of a carbide and consists of intrazonal, monozonal and
Card 2/3 p*lyzonal ranges of crystallization. The authors believe

CZECH/34-59-9-8/22
Cont.ribution to the Study of the Sintering Phase of Cemented
Carbides
that systematic study of the relevant phenomena could
lead to a substantial improvement in the properties of
commorciully important cemented carbides, to advantages
in alloying with substances which dissolve in the
ointering phase, thereby ensuring better mechanical
properties. That success can be achieved in this way
is proved by the favourable results obtained with the
Czech produced universal sintered carbide, which is
alloyed with a small quantity of Cr C ich,during
the process of sinteringtpassos inta i.'ecobalt sinter-
ing phase. There are 11 figures (including 10 micro-

TITLZs Analysis of the Influence of Addition Carbides on the
Properties of High Cobalt Content Sintered Carbides of
the System WC-Co Using Mathematical Statistics Methods
PERIODICAL: Kutuickeo listyl 1959% Nr 9, PP 791-796
ABSTRACT: the authors carried out experiments aimed at elucidating
the influence of TaC and Cr C 2 additions on the properties
of WC-Co systems with coball contents of 15 to 30%
(types G3 and G6). To prevent incorrect interpretation,
the authors made, use, of mathematical statistics taking
into consideration differences in the criginal raw
materials-ine4dition-to- differences in the quantities
or TaG and Cr3C26 The quantity of Cr 3C2 in the main
tests (0-75%) w&n based on results of preliminary tests.
The authors emphasizo that the application of mathematical
statistics in useful for workinc, put the-plans-or the
experimints. For 9arrying out the full factorial experi-
ment of the type 2 , 64 tests would have been necessary.
However, the authors used a shortened series of tests
nvolving only sixteen combinations. The pilot plant

TITLE. Hot-pressed asaiconductive ignitron ignitors
TEXT: -The-article deecribes-a~method of boron-c,arbide-ignitron-
ignitors production which combines pressing of the powered semicon-
ductive material, and subsequent firing in a non-oxidizing medium,
with simultaneous bonding or the ceramic body to the metal stems
This pressure-sinteringi or hot-pressing method, so far onl seldom
used in the OSSR, was applied by the V~zkuW "tav ro pr3kovou
metalurgii (Research Institute for Powder Metaliurgy~ in Vestec to
the production of an ignitron to be lnst~lled in an electronic weld-
ing apparatus developed by the Vftkumn;t ustav zvAra6sk~ (Welding
Research Institute) in Bratislava. The boron carbide ignitor (Fig.1)
consists of a ceramic body vhich extends into a mercury pool and a
molybdanim stem for current admission. In production tests the two
conventional methods, i. e., pressing aaid firing, were combined into
Card 1/7

a single process by using a resistance-heated graphite die (Fig. 2).
The heating current-was a_pplied-to the grap4ito electrodes-of the
die thru water-cooled copper terminals from a 15 M variable-voltage
transformer, with the secondary voltage adjustablts in 0.1 V inter-
vals within a range of 3 - 12 V. The boron carbide body was heated
and simultaneoixely pressed by a double-sidea hydraulic press, with
the pressure applied to both the male and female dies. To avoid
short circuits within the press frame, at least one die mustbe
insulated by a porcelain plate* The temperature of the graphite die
was measured externally with an optical pyrometer When the desired
temperature was reached, it was kept constant wit4n + 500 for a
certain time by adjusting the transformer voltage. AYter this timeq-
the current was cut-off and the pressure released. The sample war
left in the die to cool off. As the last operation of the press.4ng
process, the pressure on the female die was increased to achievj a
complete filling of the die cavity resulting in a perfect shapr of the
ceramle body requiring no additional grinding. Temperatures if
2,500'C and more can be achieved with the equipment used, but pres-

not exceed 10 kg/c!2 at surfaces perpendicular to the pressing
direction. ressures were precisely measured with gaSes installed
on both cylinders. Production tests were performed with semiconduct-
ing materials containing boron carbide (of last-German and Soviet
origin, both of similar quality) mixed with aluminum silicate
Al;A~-3SiOp (a product of Merck). Optimum composition was found to

be 55%B4C, 35 - 40% A1203' 3S102 $ and 5 - 10% ZrO2; optimum sinter-
ing temperatiLge (measured on the surface of the graphite die) was
1.320 - 1,340 C to be maintained for 2 minutes. To test the qualit;r
of the ignitors, ignitrons were ignited-by the discharge of a 1

TITLE: Spectral Determination of Tantalum in Sintered Carbides
--PZRIODICAI;-:
ABSTRACT: The experiments of the authors can be sub-divided Into
two parts, namely, determination of the tantalum content
by means of an a.c. are and determination by meAns of a
condensed spark. - The operating conditions in both- casfis-
are described. It was found that the results of the
spectral determination differ for the two methods.
In the case of determination by, means of an arc, the
characteristic of the current intensity depends on the
shape of the specimen which manifests itself also by a
considerable scattering in the values. The condensed
spark showed a more regular characteristic of the current
intensity and the results are more reproducible and
nearer to reality in spite of the fact that the specimen
shape also exerts an influence. For some of the specimens
a parallel chemical analysis was carried out,- in spita of
Card 1/2 analysing a greater number of specimens, the results
obtained differed from those which had been anticipa ted.

It is voint*d out that in the c
ont:Lro-a-pecison-and,--th*refore, -variations may occur-
due to imperfect houtogensity of the tested specimens.
If the tantalum carbide concentration is below 1%, the
intensity of blackening of the an&lytical tantalum
line is so weak that the influence of the background
intensity mAnifests itself. The resulting calibration
curve (Fig 8),which is based on the evaluation of the
tantalum line 2685.1 A, permits direct reading off
of the percentual content of tantalum carbide.

during recent years by further series (G4-G6 and s4-s6). Although
the fields of application of those now grades of vintered carbides
arenot accurately delimited, they do overlap. This has
advantages but it also has considerable disadvantages. Therefore,
the requirement arose for a so-called "universal" sintered carbide
which would replace carbides currently used. The universal carbide
of the composition 86.5% WC, 5% TiC. 1% TaC, 0.5% Cr3C2 and 7% Co
is suitable particularly for machining of austenitic manganese
steels for which A 100% increase in the machining performance was

TEIT: The authors tried to approach the accuracy of a simple and rapid
thermographic method to that of the calorimetric method. The system used
fer the purpose is illustrated In Fig.l. Th " measuring device consisted
of a-copper-constantan thermocouple, a 41MC-4611PUS-48) potentiometerp

were studied was either frosen as a drop onto the thermocouple Junction,
or filled into a copper foil cup (Fig.1, II). The container of the appa-
ratus was cooled in liquid nitrogen, and evaousted to (1-5)-10-2 am Hg.
A zurrent of 0.15 a was then passed through the heating coil, whereby
a steady radiative heating was attained without direct contaot b9tween

ABSTRACT; The equipment used for detemining such
jurity for solids
or liquids at room temperatures is figured (see an osure). For
low melting compound* an outor jacket is sealed to the equipment
where vacuum for regulating the cooling rate is created. The monomer
is kept under inert gas. The selection of the coQIing agent do ends
upon the crystall1vatLon temperature of the given monomer, the goat-
ing agent upon the melting point. Purity was determined according

to the crystallization or malting curves. :Crystallization curves
were determined with a SOlf-3cribing potentiometer for 0.07, 0.03
and 0 5 grad/mm,3eqsitivity. Purity was determined for trioxans
(99 6jo)O, metqlmethaerylate (99.") dimethyldichlorosilans (".01)
and octomethy tetracyclosiloxans (0.5%) with crystallization too-
peratures between 60-'and -80C. The cryoscopic constants for Cal-
culating purity weredetermined experimentally by lowering the
temperature with an artificial
a&aiture- Orig. art. has: 2 fi4x~res
