ABSTRACT: In addition to hexagonal ZrRe2 whose lattice con8tants
were nown to be a = 5.251 kX, c = 8.576 kX, and mp
8 "
two of the authors found a new compound of
Zr2 Re composition with mp 1,9000 C. In order to study
this and other Zr-Re compounds by X-ray methods,.7
different Zr-Re alloys were prepared containing 68-32;
73; 81.29; 83; 88.96; 90.25 and 96% Re, respectively.
The mixed powders of two metals were compressed into
briquets,, sintered at 1,5000 C in a He-filled ar 8

for 10 hrs, hardened from the same temperature,
annealed again at 1,0000 C for 50 hrs and hardened
from this. ZrRe. proved to change its lattice con-
stants from a a 5.273 kX and c . 8.636 kX to a
5.2F9 kX and a - 8.608 kX at the change In the alloy
compocition somewhere between 6.8-32%.Re and 13% Rej
still further increase of the Re content did not
affect the lattice constants of ZrRe 2' The alloys
with 83% Re and 88.96% Re begin to show diffraction
lines of a new body-centered cubic phase X in
addition to those of the X -phase of ZrRe2 composition.
The new phase constitutes the alloy with 90-25% Re
completely. The alloy with 96% Re shows oqually
intensive diffraction lines of the cubic phase and
of pure Re. Annealing and hardening at 1,,4ooo C did
not alter the phases readily existing in the sintered
alloys, while hardening of the alloy with 73% Re from

lines other than those of the above phases. The
newly discovered body-centered cubic phase proved
to have a = 9.693 + 0.005 kX and a = 9.626 + 0.005 kX
in the alloys cont9ining 83 and 90.25% Re, respectively.
The lattice constant, changing with the Re content,
points to the transitional nature of this phase. Its
chemical formula would be Zr 5Re 24 if the atoms of' two
metals were distributed in a perfect order like, for
instance, in Ti 5Re 24, However, its structure, similar
to that of a -Mn (space group 1 43 m), permits occupa-
tion of any atomic position by Zr or Re and this leads
to the change in the composition and lattice spacing.
The increased Re (atomic radius 1.37 kX) content on
the expense of Zr (atomic radius 1.60 kX) reduces the
lattice constant. The Interatomic distances in the
body-centered cubic phase are given in Table 2.
The mp is 9out 2,5000 C and the micro hardness about
1,000 k9/cm . Zr-Re form the only binary alloy in

ABSTRACT: Some 250 known types of structures of metals and
intermetallic compounds can be classified by space
groups, stolchiometric formulas, density of
packing, or the type of chemical bonds. The
author prefers, however, the use of coordination
numbers of atoms for this purpose, 3ince they
predetermine the form of coordination polyhedra,
the ways of' occupation of the lattt,-ri I verticet zirld,
consequently, any type of atructure. Thus, he
distinguishes 7 classes of structures, each det'ined
by Identical or closely similar coordination polyhedra:

Alloys were prepared by fusing Pd and Mg under argon in a
corundum crucible with an H.F* furnace. The t9ermal treatment
was concluded with 250 hours annealing at 400 C. X-ray
powder photographs were taken with Cr radiation. Two compounds
were found. PdMg is cubic with a ='3.16 +-0.01 KX and a

TEXT: In a previous investigation the authors together with Ye.
1. Gladlyahevskiy (Ref. 1: DAN, SSSR, 85, 81, 1952) found a ter-
nary compound NgSnCu4t with a crystalline structure of the type
M9Cu2- As tin and indium have very similar atomic radii dimensions
(1.58 and 1.66 1 respectively) and are situated next to one another
in the periodic table, the authors postulated that in the system
Mg-In-Cu there should exist a similar compound MglnCu4- In order
to confirm this supposition they. prepared an alloy of Mg (99.999%)
and copper (99.9876) in a corundum crucible with LiCl + KC1 flux
in a resistance oven. After the alloy had cooled to room temper-

ature it was studied by means of X-rays. The radiogram of the
alloy-powder, taken with copper cathode filtered rays in a Debye
camera showed the lattice constant "all to be 7.059 � 0.006 19
which is similar to that Of M9CU2 (7.019 R). However, the
presence on the radiogram of lines hko + k X 4n, lines which
are not typical of the space grouping of MgCu2' proved that the 7
structure O"IgInCu4 did not belong to the space group Fd3 - Oh
but to that F 2~3 m - T2 d9 the same as MgSnCu4, The X-ray data are
given in a table. It is seen from these data that the intensities,
calculated for the space group of MgSnCU4 (4 Mg. in 4(a), 4 Sn in
4(c), 16 Cu in 16(e) with 2 a 5/8) are in good agreement with
the observed ones. Thus the existence of a ternary compound
MgInCu4 has been confirmed. Foreign lines in the radiograms of
MgInCu4 are very weak and very few. They belong to the at-phase
(a solid solution of magnesium and indium in copper, a . 3.64 X)

and to some other phasep probably a low-temperature-modifioation
of Cu 9In4s In the lattioe structure of MgInCu4the Mg atoms have
the coordination number 16 and the Cu atoms that of / 12. Inter-
atomic distances with the same c.n. (dmg-In~ 3.06 R: dCu-CU
2.49 R) are smaller than the corresponding sum of radii (,F-r). The
distance Mg-Cu and In-Cu (2-93 A) is larger than .5 r for Mg and
Cu being approximately equal to Zr for In and Cu. The increase in
the lattice constant "all of MgInCu4in comparison with that of
MgSnCu 4 (7.044 9) and the increase in interatomic distances are
due to the.exchange of smaller tin atoms for the larger ones of
indium. The compound MgInCu 4 is one of the small numbers of re-
presentativee of Laves phases with atoms of eub-groups III - VB
in positions with c.n. 16. Indium, atoms occupy these positions
together with Mg atoms; where complete replacement of Mg by In

TEXT& On the basis of previous research it was thought that
a ternary Laves phaseshould be present in a manganese-cobalt alloy
with a metal having a smaller atomio radius than r (1,34 A; cone

1.225. To verify this supposition the author investigated an alloy
of Mn and Cc with beryllium (r a 1.13 2) the system not having
been studied before. The composition of the ternary Laves phase
of this system should be Mn (Co Be) and the crystalline etruc-
ture to correspond with the MgCu2 0i MgN12 types that of MgZn2

compound MnBe some quarternary phaset containing oxygen or si-

author prepared another 6 alloys in the series MnOoO.8-0.9U1.2-

these alloys were homogensousq consisting of two phases of the

cooled copper hearth and an insoluble tungsten electrode, under
argon (300 - 4,00 mm Hg pressure). The alloys were not sAje9teO
to heat treatment. X-ray investigation of the alloys was carried
out by the powder method in a Debye camera (57-3 mm diameter)
and in a Preston camera with chromium irradiation. The follow-
ing properties were determined for a few alloys; melting point,
hardness microstructure and microhardness of the structural
components. The melting point was determined in argon (4oo
mm Hg pressure) by the drop method, in which a hole drilled in
the specimen is filled with the molten metal and the temperature
determined by means of an optical Pyrometer, calibrated with
reference to the pure metals under identical conditions. The
hardness was measured in a Rockwell machine according to scale
B (2.5 mm diameter ball, 100 kg load), the microhardness was

TEXT: It in stated that the hafnium-beryllium system has not
so far been investigated. The alloys prepared by the present
authors contained 0-05, 0.1, 0.25, 0-5, 2.0, 10.0, 20.0, 33.0,
62-5, 70.0, 80.0, 84.0, 91.0 and 95.5% by weight of hafnium. The
alloys were prepared by alloying hafnium and beryllium in an argon
atmosphere in a high frequency or an arc furnace. The specimens
were then subjected to X-ray analysis. For some alloys the
melting point, the hardness and the microhardness of the
structural components were determined. The rAicrohasdn::s H $L was
determined with a load of 100 g to within +30 kg/mm u ng a

TEM -There are 31 systems of intermetallic compounds with a P-uranium
type structure, the so called sigma-phase. The components of these systems are
on the one hand elements of sub-groups 4 - 6 of the periodic system, and on the
other hand sub-grouPs 7 - 10. A similar diztribu~ion of components is also
shown by type oc-Mn and Cr Si compounds. Considering the similar structure-of
Cr3Si and sigma phases, ii can be expected'that the latter will also be formed
.by elements of sub-groups 11 - 15. This hypothesis was confirmed by the authors
who discovered a compound with a sigma phase structure in ternary system Cr-Ni-
-Si. None of its binary systems contains a sigma phase, but system Cr-Ni shows
a tendency for the formation of such phases, and in system Cr-Si a Cr3S' type

compound is being formed. The discovered sigma phase composition is Cr 13N'5Si2;
its constants are: a - 8.769, c - 4.561 kx, c/a . 0.52. A second compound was
revealed in Nb alloys with Al, obtained at the Institute of Metallurgy AS USSR
by Ye. M. Savitskiy and V. V. Baron. A radiographical analysis shows that the
Nb2Al compound belongs to the sigma phase type. Its constants are: a - 9.951
c w 5.18 kX; c/a - 0.52. This is the first sigma phase containing Al. The
distribution of atoms In Its structure corresponds to a complete order (the Nb
atoms are in locations with coordination number 15 and 14 and Al-atoms with co-
ordination,number 12). Crystallcohemically the compounds approach the Nb 3A1
(Cr2S~i type) compounds and sigma phases In systems Nb-Re and Nb-Pt. Moreover,
the authors have discovered a number,of ternary systems whose radiographs re-
semble.thoBe of sigma phases but are not identical with them.

TEXT: The authors confirmed by x-ray analysis the existence of TaNi 21
TaNi (or a compound with a composition near to it), and Ta2Ni; they also
defined the crystal structure of the latter. The 3 compounds have been
identified by I.I. Kornilov and Ye.N.Pylayeva (Ref.5: Zh.neorg.khimiis
in press), being formed in the following reactions; (1) Ta1Ni -71 +
2 f-~-
TaNi (1420*0; (2) TaNi e + Ta Ni (15700C); and (3) Ta Ni +

(17700C) , where )d is a solid solution of both me tals. Specifically,
lOg samples of alloys were prepared by induction melting in an atmos-
phere of purified Ile. Homogeneous structures and compositions were en-
sured by firstlyg using 9996% pure Ta and 0000-grade Ni, secondly by

avoiding the use of crucibles in melting and thirdly by carefully con-
trolling the com9 osition of charges. The alloys were homogenized for
1000 hre. at 800 C, prior to their x-ray analyais. The latter proved the
existence of the 3 compounds at 8000 0C. X-ray powder photography (Cr
K L-L -radiation) of Ta Ni indicated a tetragonal body-centered lattice,
with the constants a ? 6.216 � 0.005 2, c - 4.872 1 0.004 1; c/a = 0.784a
These constants are similar to those of Ta 2Si, thus indicating for Ta 2Ni
a structure of the CuAl type (space group 14/mem - D 18 ; 4Ni in 4WOO

Gladynhavokiy in corundum crucibles in the Tasman furnace in an argon
atmosphere. Both emission and absorption spectra were taken. The
reflecting (16TO) surface of a bent quarts crystal was used. The method of
inclined planes was applied to magnify resolutich up to 10,000 times.
Emission spectra were taken with an aluminum anode. A tantalum &nod* was

tion between the difference (Ax) of the electronegativities of the
components of a binary compound*and the energy distance (AE) (KO 1 05

ABSTRACT: The existence of compounds of the rare-earth elements with metals, their
composition and the type of crystalline structure were investigated, with particu-.
lar attention to the similarities and differences between the various rare-earth
i elements,as well as between these al wants and their neighbors In the periodic
table. The systems of La, Ce, Pr, Nd, Dy, Er, Gd, Tu and Y with magnesium were
investigated first. It was found that there are no cipplate analogies In these
systems, but that the system Y/Mg Is closer to Er/Mg than to the La/Ce system. In
the systems of rare-earth elements with zinc, aluminum and germanium, new compounds
were found, the structural parameters of which are given. it is Interesting that
cth sy?)2w YMI differs from the system Er/Al and Is similar to the system with

Iaddition to the totragonal one.' Systems with cobalt and Iron were also Investiga-
ted and their parameters are given. An the La/Fe system no compounds are formej.
A weakening tendency to form compounds with a decreasing order number of rare-earth
elements is also found In many sys tems with-manganese. Finally, the ternary sys-
tems cerium-transition metal (or copper)-aluminum and cerium-aluminum-silicon were
investigated and their lattice constants are given. OrLgsartehas; no graphicso

experimental work to studi the intermetallic compounds of rare-earth metalse The
aspects studied include isostructures atorphotropy, dependence of lattice constants
on atomic number
and the formation of tertiary compounds. In view of inadequate
data on isostructural compounds, the exact claracter of such series cannot be
predicted, but it is thought unlikely that conplete isostructural series will be
found for the rare earths (i.e., series including all the rare earths). The
compounds will most probably form a morphotropic series of identical compositions

series are comonly polymorphouso Successive changes in atomic number lead in
some series to changes in both composition and structures The atomic radius,

characteristic in d6termining isostructural and morphotropic series. Compounds of

ABSTRACT t The authors, have prepared alloys of Th p Ho t Tu, Yb I and Lu o:ntaining
62.8 atwaio % of US in the charge (Leep corresponding to a composition of R
by alloying Th ~(99-1YAt 0.5% other rare earths) go (97.4%j 20% other), Ta t94;-'I?,llt
1.5-1% other)# Yb (99.94j 0.005% other), and Lu 65-Z6, 3.0% other) with lk (990
in crucibles of XgO with a flux (LiC1 + K01) in a Tamman fiamace ka,toosphere of He
or A). The alloys are silvery whitag and they oxidize in a.irp but much more slafty:
It than alloys of Mg with rare earths of the Ce. group. X-ray studies show that Ta and
.Lu alloys contain pure compounds of the Ti ?'924 typet but teat Th and Ho, alloys
contain this type of compound In equilibrium with other oomjxnm4s# particularly
'TbVg3 and K*Mg:2. Experimental intensities for TU^A (V'sWa observation)
are in
