of 11h and Cd. Because of the loss. of lithium 64-m 'fh-4-melt during tho preparation of
this alloy, the introduction of lithium (and cadmium) was carkied out under a speoial
flux consisting of a eutectic mixture of lithium and potassium chloridQso This flux
was found to prevent the loss of lithium-to a considerable,extent; hewevers as the
31-ithium content ofthe Alloy inereasosthis protection.becomes lose effectivei Partia-
ular attention must be paid to the quality of preparation of the f1wt and to the

of the 16dide Method of Refining Zirkonium.
Energijaj 1, fase. 1, 43-51 (1956)
Issued: 3 / 1956
The preaent investigation served the purpome of explaining the principles of
the process of refining as well as of problems of practical interests.
Tests were carried out in small glass- and quartz vessels under
10-4 nwi vacuum, in which glowing tungsten wires fastened by molybdenum holders
were ut3ed as seperators. Temperature was measured by means of pyrometers.
Besides contradictory statements made in literature concerning the influence
exercised by the temperature of the wire on the course taken by reaction,.s. con-
siderable dependence was found to exist within the range of operation of from
1200 to 15000 0. In contrast to statements made by other authors# who believe
in a talight increase of dissociation constants within the range above 14500 CP
it is assumed that ZrJ -partial pressure near the wire cannot increase infini-
tely because the partih pressures satisfy the equation P., - PZrJ4 a Ptotal'
The influence exercised by the quantity of iodide on reaction velocity:
In thecase of small quantities, 3 -,5 mg/50 g Zr, reaction is very short,
apparently because of the formation of low iodides. The curve shows a distinct
maxi mum at 12 mg/1000 CM3 vessel volume.

Atomnaja Energija,.L, faso. 1, 43-51 (1956) CARD 2 / 2 PA - 1604
For the dependence of the precipitation velocity on vessel temperature (and
thus on the temperature of the metal) different authors give different data.
it waa found that, on the assumption that the temperature of the ZrJ 4 is con-
stant, and assuming an optimum steam pressure, the temperature of the vessel
can vary between 235 and 7001 G without reaction velocity being influenced.
In the course of the investigation of the problem as to the existence of a
second maximum above 4200 C the following two oases were distinguished;
1. If Zr is fine, i,e. if its surface is largo, low iodides will formt and at
higher temperatures tetraiodide will be formed which leads to a 2. maximum.
2. In the case of small quantities of the metal in large pieces, there will
always be a surplus of ZrJ.4 which determines the vapor pressure and thus the
reaction velocity, the optimum of which is at about 235-240 0 0.
This hypothesis was confirmed by a further experiment in the course of which
vapor pressure was measured in the vessel.

therein contained are of importance for the selection of the electrolyte on
the occasion of the winning of,thorium. by means:of electrolysis
The main method employed by the authors for the investigation oi these state
diagrams was the thermal analysis (-Nith-automatic recording of the simple and
differentiated'ourves) of the fused salts. As'an auxiliary method-they chose
phase analysis by the direct comparison of the X-ray pictures obtained with
those of pure raw materials: ThF f NaCl and KCI. Furthermore, microstructure
analyses of the microsection surfaces of these salt alloys were carried out.
Production and properties of the material examined are described. There follows
the discussion of the investigation of the systems NaOl - ThF and KC1 - ThF

Zi -conoluslions: The state diagram found here of the system NaC1 ThF 4belongs to
the'diagrame of eutectiotype with lacking displaoeability of components in the
solid state, The eutecticum is at 23 molecular percents ThF and 7120 C.

ABSTRACT-. Taking the hypothesis that processes of diffusion are decis-
ive in the kinetics of the process of the tran'sfer of Zr to a cen-
tral filament,(F), it is shown that the rate of deposition of the
Zr on the F is directly proportional to the pressure of free I
near the surface of theY, and that this in turn determines the
temperature of the F. Inasmuch as the vapor pressure of the I
aIround the F cannot exceed the total pressure in the apparatu s,
which is governed by the wall temperature, the rate cof deposi-
Card 1/2 tion of Zr on the F ceases to increase with a further rise in F

temperature after ti, c attainment of som specific F temperature which de-
pends upon the total pressure in the apparatus. These concepts afford an
explanation of the available experinnental data of various authors on the de-
pendence of the rated of Zr deposition, upon an F on tAe temperature of that F.
It is also shown that: the quantity of QA introduced by Wririg and Moli6re
(J.H. Ddrifigi-. K. Moliare, Z. Air Elektrochemie, 1952, Vol 56, Nr 4,
p 403) inthe equation log a const QA/RTD, where a is the. rate of Zr depo-
sition and TI),'.:: the temperature of the F, is related to AH in the process of
dissociation by the expression QA:* AH/4. If account be taken of the forma-
tion of lower Zr iodides on the. surface of the F, the value Of QA, it appears,
is also dependent upon the vapor pressure of the Zr14.

TEXT. The internal friction and, thus, the modulus of rigidity of uranium
as dependent on temperature was measured by means of a relaxator which
recorded the damping of the free torsional oscillations of a sample. A
ur-ani-um wire of a length of 32G mm (diameter 6.98 mm) and a purity of
99.9~ was used as a sample* The frequency of oscillations of -the wire in
a vacuum of 5.io-5 torr was " 2/sec. The rate of heating or cooling
varied in the range 5 - 0-50C/min. The accuracy ol?' temperature measure- W,
.ment was � -1-50C. According to the three phases of uranium, the samples
were annealed at 630, 645, 670, 720, 755, 768, 850, and 96oOc. The
course of the measured parameters is represented for the various
temperatures in Figs. 1-5. The results of measurement lead to the

following conclusions: (1) The bend in the into rnal friction curve in
--ihe-temperature-range 450 5000C is caused by the tenacity of the
grain,Iboundaries, This tenacity--disappears afte-rannealingin the
and y-pha'ses. This-is the result of the recrys tall i-Mit ion of phases--
due to lower mobility of the boundaries. (2) in temperature changes,
the polymorphous transformations of uranium are accompanied by an
isothermal change in internal friction. The changes take place during
heating as well as during cooling in both directions. (3) The most
plastic y-domain, which has a body-centered cubic lattice, is
characterized by a high internal friction. The tetragonal P-modification
whibh tends to brittleness, has the lowest internal friction. It is
generally true that the internal friction is related directly to the
crystal lattice and to its capability of plastic deformation. There are

TEXT: As starting material for different alloys, zirconium iodide
(purity 99.7% by weight) and distilled beryllium (purity 99.4% by weight)
were used. The cast and annealed samples were investigated metallo-
graphically. The annealing temperature lay between 7500C and 12000C and
the annealing time between 250 and 35 hours. The samples were analyzed
thermally in vaouum at a heating or cooling rate of 5 - 70C per minute.
For alloys containing 2.9, 5.04, and 8.9 per cent by weight of beryllium,
critical points were determined. X-ray analyses (quantitative phase
analysis) we're maide by photographic as well as ionization methods. The
apparatus PKY-86 (RKU-86) and YM-50M (URS-501) were used depending
on the method. The microhardness was mqasured according to Rockwell by

iseans 6f a diamond cone with a load of 15 kgo in the zirconium -
beryllium system there are four intermediate phases; ZrBe2, ZrBe6, ZrBeq,
and ZrB612. The first three originate from peritectic reactions at
12350C, 147500, and 15550C. The last phase originates with an open
ma.ximum at 1645'DC. At 9650C and a beryllium content of 5% there results
an eutectic between ZrBe2 and zirconium. An addition of beryllium to
zirconium lowers the temperature of a-P transformation and leads to an
eutectic at 8000C. The solubility of beryllium in a-ziroonium is less
than 0.1% by weight and in O-zirconiun less than 0*3% by weight. The
solubility of zirconium in beryllium does not exceed 0*3% by weight.
There are 8 figures, 1 table, and 5 non-Soviet references.~
