Title: On Aluminum Boride AlB12
Original Periodical: FU. meetallov i metallovedeniye, 1955, 1, No 3, 5&-566
Abstract: AlBip crystals were obtained by aluminum-thermal reduction of boric an-,
hydride in crucibles. The contents of boron in the beads obtained during the melt-
ing amounted to 82.5 - 82.8%. Almost all the AlB:L2 crystals were double growths.
X-ray structural investigation has shown that AlB12 belcogs to the tetragonal syngony;
and has the following periods: a 10.1 � 0.1; C 14.3 � 0.4 A and c/a = 1.41, P 2.79 � :
0.02, number of atoms per elementary cell approximtely 200. The electric rdsistiv-
ity of the pressed powder of A1312 is related to the density as follows: In
7.588 y - 15.03; where jp is -the resistivity (ohms/cm), and y the density of tre
pressed briquette. The electric resistivity of the specimens of AlB12 in compact
state, prepared by hot pressing, amounts to approximately 103 ohms/cm, the thermal
coefficient of electric resistivity is 0.4%/deg. The micro-hardness of AlB12 is
close to the micro-hardness of B.

Work on the reduction of metals and some nonmetals (31) with metals
is reviewed. Reference is made to the use of metal hydrides as reducing
agents in processes of this type. The physicochemical aspects of the
processes involved are discussed in detail.. The heats of formation of
sow oxides and halides (including CdC12, ZrC14, UCL4, RaC12, LiCl, CeF 3)
LaF , and LiF) are listed. The free energies of formation of halides in-
cluaing CeF ThF Zr F4, Ce C13,,Th C14, and Zr C14 are given. Frac-

combustion of the mixture, and,(b) the oxidant must represent a rela-
tively stable, nonhygroscopic compound, at least in the temperature
range minus 600 - plus 600."
The subject matter of the article is based to a considerable ex-
tent on data taken from"GSSR publications: out of 45 references in them

In conclus on application of metal-reduction processes in pyrotechnics,
specifically in military pyrotechnics, is discussed on the basis of inform-,
tion given in two USSR hand-books on the subject.
The section on pyrotechnics includes the following passage:
"Among metals which can be potentially applied as metal fuels one
may mention Be, Al, B, Li, Mg, Ca, Si,.Ti, V, Zr, and their alloys. The
highest temperatures during combustion.must be developed by Zr, Al, Ca,
and MS. At present, no metals except Mg, Al, and their alloys are ap-,
plied for this purpose, although some metals which are extensively used.
in contemporary metallurgy would be suitable for this application either
in the pure state or in the form of their alloys.
"To obtain the*maximum effect from a metal,entering into the composi-I
tion of a pyrotechnic mixture,.the oxidant must be appropriately selecte-a.'~

Title : Diffusion of Boron, Carbon and Nitrogen Into Transition Metals of
Groups IV, V A1,[D V! of the Periodic System
Orig Pub: Dokl. AN SSSR., 1956., log, 1110 3., 582-585
Abstract: Reaction diffusion of B and C into Ti, Zr, Nb, Ta, Mo and W is uti-
lized to elucidate the effect of vacant d-electron sites of metals
and of ionization potential of B and C on the diffusion constants D
and Q. Reaction diffusion results in the formation of.the compounds
TiC, ZrC, Ta,_C, Nb C, W C, Mo C, TiB- -, TaB,, NbB , Mo- Band,V,B.
Values of Q on diffusion of B, C and N (from another paper) into trans-
ition metals of groups IV, V AND VI, reveal the fo" owing regularities:
1) in the same group of the periodic systerp Q increases with atomic
number of the metal; for the given metal, Q increases in the series B,
C, N. Low values of Q in the case of B are attributed to the low ioni-

zation potential of B; 3) on transition from metals of groups IV and
V to those of group VI, Q increases slightly in the case of B and
sharply in the case of C. This is interpreted on the basis of the
theory of Pauling (Pauling L., Phys. Rev., 1938, 54, 899). Differences
in values of Q on diffusion of B into metals of groups IV, V AWD VI,_
level off in comparison with C; the authors attribute this to decreas-
ing effect ofdeficiency of d-sublevel as a result of the formation of
structure elements from atoms of B (chains, layers and framework, con-
nected by covalent bonds).

ABSTRACT: The properties of bo= carbide compared with other hard
materials are stated in a numerical table. The preparation of
components of boron carbide by hot sintering under-pressure is
discussed and described with the help of drawings and numerical
data7 taken mainly from foreign periodicals and patent litera-
ture. Some applications are discussed; original applications
are mainly those for diamondless dressing of grinding wheels.
Tests carried out at the First National Ball Bearing Factory
(lGPZ imeni L.M. Kaganovicha) with the internal grinding of holes.
showed that a dressing pencil of boron carbide of 18 mm diameter
and a height 23 mm stood up under shop conditions to 168 hours
of service, and so ensured hole tolerances of between 8 and 10
microns. The ratio of volumes removed from the grinding wheel
and the dressing pencil varies between 800 and 8 000 ior boron

ABSTRACT ZLn attemDt is made here to determine the relation between the elec-
tronic work function in thermoemission and the electronic structure
of transitive metals ( and their compounds with ~b'bron carbon
and nitrogen). It is shown that the work function depends on the
atomic structure of the metal and decreases with decreasing degree
of screening of the electrons of incompletely occupied d-atom shells
of transitive metals. The work function can be brought into connection
with the quantity of dispersive power of the atoms of transitive me-
tals which are characterized by the criterion 1/Nn. 11 - chief quantum
figure; n - the number of electrons in the incompletely occupied
d-shell, it decreases with increasing 1/Nn. In metalloid compounds
of transitive metals with bor6n ., c-arbon and nitrogen the work func-
tion should increase with increasing I/Nn for the corresponding
transitive metals.This is confirmed in the case of borides,but in
the case of carbides and nitrides it can not yetbe considerled to be,

exerts considerable influence on' the amount of the work function
of metalloid compounds. A reduction of the work function is to be
expected in the M02-MeC-HeN series, where Me is a transitive metal
of groups lVa, Va, or VIa. The work function is in most cases smal-
ler in the case of metalloid compounds th an in that of the corres-

ABSTRACT: Transition metals form compounds of high'electrical.-
conductivity with silicon (Ref.1), which can become
superconducting (Ref.2), which have a metallic lustre,
etc. Orystallograp'hically, silicides are substitutional
phases (Ref-3). unlike carbides and nitrides, which are
interstitial, or borides, which shov, some signs of being
insterstitial, as well as some layered features typical
of silicides. The metals used were Ti, Nb, Ta, Cr, M0,
W1, Fe. Co and Ni; the diffusion data were worked up to
give the activation energies of diffusion. The cY711ndrical
sDecimens were saturated with silicon in an oven while
'immersed in silicon powder containing activating additives,
The thicknesses of.the silicided layers were determined
from etched cross-cut sections. Wafers less thick than
the silicide layer were examined with X-rays and by

to consist of disilicides. The results were worked up
in the normal-a-ay for reactive diffusion (Ref.4). The
activation energies (in cal/mole) given in the Table were
derived, and compared -with those for B, 0 and N in the
sqjne metals (Refs. 4, 51 7). The silicon was found to
give the lowest activation energyl although, formally,
speakinG, one would have expected it to give the
13rges since silicon has the largest atomic radius

respectively. The figure shows that the activation
energy is inversely proportional to the ionization
potential of the metalloid. The electronic properties,
rather than the radius, are therefore heredecisive.
Although silicon gives lowactivation energies, the
silicides have comparatively low values of the physical
-oarameters, relative to borides, carbides and nitrides.

nitrides (Ref.8), and partially the borides, are inter-

In the first three the shear deformation in hardness

the silicides, having graphite-like layers weakly bonded
together (Ref.10), deform comparatively readily. The
silicides therefore often melt even below the meltingpiint of

ABSTRACT: The first part of the paper deals with prewar and
pre-1917 developments, mentioning that in 1932 fifty tons
of "pobedite", thirty tons of I'vokar" and sixty-nine tons
of "stalinite" were produced and during that year these
cemented carbides were used in 1400 Soviet plants. An
All Union Scientific Research Institute for Cemented Carbides.
(Vsesoyuzniy Nauchno-Issledovatellskiy Institut Tverdykh
Splavov) was organised, the work of which determined to
a certain extent the development of the Soviet cemented
carbide producing industry during the post war years.
This Institute contributed a great deal to the development
of the process of manufacture of shaped cemented carbide
components. It is claimed that the Soviet Union is
In the forefront as regards production of cemented carbides
and this resulted in considerable successes in the fields

producing pure borides of high melting point elements
was developed (Ref.8) and also methods of producing
silicides and a number of diagrams of state of carbides,
borides, silicides and nitrides were investigated (Refs.9-11).
Cemented carbides were used as substitutes for diamonds in
trueing grinding wheels and for machining hard watch and
instrument jewels of the type of rubies and leucosapphires.
New thermo-emitters for electronic,devices (lanthanum
boride) were developed and also high resistance resistors.
At the Institute of Metalloceramics of Special Alloys,
Ac.Sc. Ukraine (Institut Metallokeramiki Spetssplavov AN
Ukr.SSR) intensive investigations are proceeding relating
to cermets which consist of composition of oxides with
carbides and of metals with oxides; a considerable part
of this work was carried out by Ya. S. Umanskiy,
G. A. Meyerson, B. F. Ormont and V.V. Grigorlyev (Ref.12).
An important contribution to the theory of alloys of
hard, high melting point compounds was made by
I. I. Kornilov (Ref.13). The Soviet chemical industr7

ABSTRACT: Efforts were madelto improve the method of preparing thorium sul-
fides by direct combination of the thorium. with the sulfur.- A
thorium powder containing 99.8% of Th and thoroughly purified
sublimed sulfur were used as basic,matirial for the experimeints.
The first series of tests was conducted at temperatures ranging
from 400 to 8500 with intervals of 50 to 1000 with a running period
of about 30,min. Parts of the prodicts obtained were chilled in
the open airand parts in an H2S stream. During the ohilling of
reaction products in a hydrogen sulfide stream the sulfur content
increased sharply and the total.of Th+ S, reached 100%, especially
in experiments at 6000. The composition of procbets-obtained with
consideration of the abseme of free Th is Th 253- ThS-and Th2S,4

Saturation of specimens.of the above metals* with B and Si was achieved
in a stream of purified H at various temperatures (from 1000 to 20000C

Activation Energy During the Diffusion of Boron, Carbon, (cont.
into the boride, silicide, or carbide phase, (CI-C?) is the difference of the concentra-
tions of the metalloid on the borders of the layers, and K is a quantity dependent on
the radius of the specimen, the thickness of.the diffusion layer, and the saturation
time. It was found that the activation energy of the diffusion of the metalloid into the
transition metals of a given group increases with increasing atomic number of the
metal. The activation energy increases during the transition from the borides to the
carbides and nitrides. These regularities are related to the magnitude of the ioniza-
tion potential of the metalloid and the degree of incompleteness of the CL -electron.
sublevels of the transition metals. The activation energies of the reactive diffusion
were compared with the crystalline lattice -energy of the corresponding carbide and
boride phases determined through calculations. The activation energy decreases
with the increase of the energy of the lattices which are formed upon the diffusion of
the phase.

ABSTRACT On the occasion of the radiographical investigation of the
tungsten-boron system 3 borides were found in the beginning:
the tetragonal W23 and WB as well as the hexagonal W 2B5*
Later the existence of a high-temperature modification of
tungsten monoboride P-WB was determined. Aacording to publis-
hed data W2B ( I -Phase) kas very close homogeneity limits,
whereas (6-phase), has wider ones. The previously determine&
phase WB2 is probably identical with W 2B5 if there is a
deficiency of boron-atoms. For the purpose of a pricise de-
termination of the phase range of the tungsten-boron diagram,
the author investigated alloys of this system by the methods
of mioro-hardness as well as by methods of radiography and
metallography. The results obtained make it possible to sug-,
gest the following phase ranges of the tungsten-boron system:

Based on the roentgen- and chemical 'analyses as well as the measurements

that the diffusion of B into Ti, Nb, Ta, Cr, Mo, W, Fe and Co, of carbon
intd'hiPZr ANbY'1Ta,v1Cr,-1Mo,-1W andIlTo and of Silicon into Ti is an active
diffusion, i.e., it is accompanied by the formation of the pertaining
boride, carbide and silicide phases. Based on the microscopic investigation
of the thielmesses of the diffusion layers as well as on the data of the
regions of homogeneity of the pertaining phases and the results of the
chemical and roentgen-analyses,'the activation'energies have been calculated
and equations of the temperature dependence of the coefficients of diffusion
of B,, C and Si into some of the metals indicated were derived. It has been,--_,

(:do Si 2) which in recent years are used at high temperatures. The
extremely high resistance to the influence of atmospheric oxygen
0
at a temperature of up to 1700 0 and other agressive gases, as
well as to acids and molten metals is to be considered its basic
property. Its properties and behavior at different temperatures
are described in detail; K. I. Portnyy also participated in these
tests. The behavior of Mo Si in the atmosphere of various gases
g
and in the air is represente
by the curves of figures 1 and 2 and
then exDlained. Molybdenum-disilicide is resistant to the action
of the following molten metalst sodium, lead, bismuth, tin, mer-
cury and other metals which do not form disilicides. Tabl- I shows

table 2). The other mechanical and physical properties of MOM
are enumerated in detail and explained and its use at high temp
perature is described in, detail. Figure 3 shows a molybdenum heat-~
er with and without a MoSi 2-covering. There are many pos ,sibilities
of the preparation of Mosi -powder , the simplest one consists,of
a direct combination of mo~ybdenuat with silicon: Ho +23i = MoSi 2.
The tests of a direct synthesis were perforated together with N. M.
Popova. Up to a temperature of 1100 aC the tests were performed in
a laboratory furnace TK 30/200 in an argon atmosphere (figure 4),
at higher temperatures in a vacuum resistance furnace. In the La-
boratory of the Institute for Powder Metallurgy and-Special Alloys
AN Ukrainian SSR MoSi was prodwed at a temperature of 1000 0C and
one hour halt. I. D. Kadomysellskiy also participated in the ex-
periments. Figure 5 records the porosity dependence of the test
samples on the sintering temperature and figure 6 that on.the,.time

a) MoSi is ona of the compounds most resistant to scale' and chemi-
cal inHuences, which property is connected with its hi-h thermal
conductivity, hardness and stability. It is used for the produc-
tion of refractory products, heatproof alloys and covers for mo-

ABSTRACT: Chromium carbides, although having a relatively high
chemical resistance interactwith titanium carbide forming
ternary phases C-Ref.2') and, for instance, for such systems as
TiC-Si a eutectic type of diagram has been observed which is
obviously linked with the low loss of free energy during Sic
formation. The author considered it of interest to investi-
gate the relation of other Ti compounds (borides, silicides,
nitrides) with metals of the ferrous group. In this paper, the
interaction was investigated of titanium boride with Fe, Co
and .6i. Since the work was not aimed at detailed investi-
gation of these systems~atechnique was applied which is des-
cribed in a paper by A.N. Zelikman and D.S. Bernshteyn [Ref.4-1,

method [fZef - 51 and containing 68. 90'16 Ti , 31- 02% B and 0. 02016 Cfre

titanium boride as compared to systems containing titanium
carbide. This is attributed to the presence of strong,
covalent bonds in titanium boride which levels out the diff-
erence in the behaviour of boride in its interaction with
metals of the ferrous group. It is possible, in principle, to
utilise titanium boride as the hard component of metallo-
ceramic sintered carbides. There are 5 f igures, 2 table s - and
5 references, 3 of which are Slavic.

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=
teristics,as well as ofthe 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-Dres=
sing and sintering of metal.powder or powder mixtures re=
spectively are carried out either simultaneously or by
soaking the porous pressed article in liquid metal, or
