ABSTRACT: Magnetic saturation (MS) was measured on a magnetic
cryostat with a magnetizing solenoid creating a field of up to
6000 oersteds held uniform to within 0. 5% per 100 mm. The
measurements were made in the 20. 4-830K interval by the
ballistic method with "incomplete compensation", yielding
an error of :~ 0. 5%. Temperature was measured by a Pt re-
sistance thermometer accurate to 0. 1-0. 31. The investiga-
tions were conducted on ellipsoidal specimens of Ni-Fe al-
loys containing 35- 100% Ni, in which an appropriate heat
Ca rd 1/2 treatment was employed to create order or disorder. The

An Investigation of the Magnetic: (cont.
relationship of MS to temperature at low temperatures is better described
by the "T3/2,, than by'the 11T211 law which is usually employed at the higher
temperatures. An increase in MS is observed when the alloys are annealed;
this may be explained by the effect of the ordering process. The change in
mean atomic magnetic moment on ordering is 3-3. 5%. The -'T3/?" law for
MS makes it possible to calculate the 191 parameter characterizing the ex-
change reaction in the alloy. Annealing causes 08 to increase by about 15 %
relative to the value for the hardened state. An analogy with the similar
Fe-Pd system leads to the conclusion that this change in exchange energy
is due to the ordering processes. The Curie point 6 of the corresponding
alloys undergo little change as this occurs. The 1910 ratio dimishes with
with diminution in the Ni content of the alloy, inasmuch as 91and 0 are
dependent to different degrees upon the value of the mean atomic magnetic
moment and consequently change differently with variation in the composi-
tion of the alloy.

ABSTRACT: In iron alloys with an Al content of 3-IOwt% tbeformation of
the K-state is observed. This is a stato which occurs in
tempering hardened and deforped alloys, and in which con-
currently an anomalous increase in the electrical conductivIty
takes place. The structure of these alloys is that of a one-
phase solid solution with a cubic-body-c-entered lattice. In
the case of more than 10%Al ft ordered structure of Fe3Al is
observed. Since the-methods of metallog-zophy and normal radio-
graphy offer no results oscillation X-ray spectrograms and
radiographs of diffuse scattering were carried out with mono-
brystalline samples by using the monochromatic '1-'o K. emiesioll.
The alloys had the following composition: 1) One containing

a maximum increase of electrical conductivity. 2) A dit-
ordered one-phase alloy with 8% Al. 3) An ordered alloy viih
12% Al was investigated for the~purpose of comparison. On .
figures I and 2 radiographs of alloys with 10 and 12% Al are
shown, and it is pointed to the changes which take place due
to tempering. This is explained by a change in the Fe 5A1 por-
tion. Figures 3 and 4 show Laue diagrams of samples of the
alloy with 8% Al. Also in this case the changes due to tom-
poring are visible. From the comparison of the results wi.th
those obtained in the papers (Rofs 1, 2) it may be concluded
that an anomalous change in the electric re8istance in found

An ordered domain structure is formed (domain dimensions -100
The increase in the electric resistanco is explained by the
increase in the electron scattering at the domain boundaries
provided the domain dimensions and the electron wavelengths
are of the same order of magnitude. In the case of the alloy
with 8% Al the change of the electric resistance is connected

TEXTs To clarify the dependence of saturation magnetizability 1. on tempe-
rature T in the sub-hydrogen temperature region, three specimens of FO-Ni allqys
were studied, containing 34.6, 68.8 and 7508% Ni, and one apecimen of a Fe-AL al-
loy with 24.9% Al content. It, was measured by the compensation (zero, null) bal-
listic meLthod, ensuring a prooision of relative measurements of 0.1-0.2%. The
data obtained do not give a basis for defin!te conclusions*as to a functional de-
pendence, besides the linear one, in 'Lie indicated reglon of accuracV. The data
of 1. measurements at T w 140K are of interest, since they support the result on
the bide of low temperatures for the measurements at T m 200K. The results of Is
measurement In a field of 1,800 oersteds are given. From these data follows that

tained the conclusion Is drawn that as the temparature goes down, the quadratic

TITLE: Influence of mechanical action on the magnetic structure and

no. 12, 1961 , 1518-1523
TEXT: The influence of a sahanical stresses and the conditions of
stabilization of the magnetic properties are studied. According to Ye. I.
Kondorskiy (Zh. eksperim. i teor.. fit., Up 1110 (1959)) the degree of the
stability of magnetization of a ferromagnetic, placed in a field of elastic
stresses, can be changed by choosing an adequate magnetizing procedure.
The influence of compressing stresses directed perpendicular to the
magnstio flux on the permeability in different fields in case of magnetiza-
tion on the principal curve and on the ideal curve of thq alloys 7914MA
(79M) and 76NKA(76NKhD) (magnstostriction, X,/-0.2*10-0) was studied.
The boundaries of the principal domains are less displaced under the actich;
of external stresses than the boundaries of subdomaine and of additional

domains. Simplifying the magnetic structure Sby adequate processing)
an alloy by converting it completely into 160 -domains, increases the
stability of the magnetic properties, impair, however, the quality.
Simplifying the magnetic structure can~most easily be achieved by
diminishing the thickness of the material. Since the internal field acting
on the 160 -boundaries is equal to zero, the 1800-boundaries are much less
displaced by elastic stresses than the 900-boundaries. In searching
magnetically stable materials, special attention should be paid to such
materials as have a suitable optimum amount of defects. The alloys
tending to brittleness (such as iron with high silicon content, iron
containing 16% Al and iron alloyed with Si and Ni) are magnetically m,3r6
stable. Magnetic stability may bo diminished by inclusions acting as
stress concentrators. Due to considerable irreversibility, the fixation
of the 1800-boundaries of the domains by inclusions must be avoided in
plastic alloys and is applicable only in case of brittle alloys. Tho
dependence of the a-c resistance on alloys 68H (68N), 79NNA, subjected to
thermal pre-treatment in vacuumt and on an alloy containing 79% Ii, 5~ Re,
16% Fe has also been determined by the method assumed by the authors,
Institute to be the optimum method. The resistivity of alloyed specimens

1 to 8 kg mm- its active resistivity is a linear funotion of load. In
rhenium-containing alloys, the galvanoslastic effect is stronger than in
molybdenum-containing alloys (79NUA). The sensitivity of the strain gage
constructed from rhanium-containing alloys is expected to exceed that of
strain gages made from Constantan alloys by two orders of magnitude. There
are 8 figures and 3 Soviet references.

ABSTRACT:
A method of protecting superconduciors from damage during the transition from
superconducting to normal state has been developed. The 65BT superconducting
niobium-ritanium alloy wire (65Z niobium and some zirconium) was developed by
the Institute of Precision Alloys at the Central Scientific Research Inatituti`
of Ferrous Metallurgy.. At 293, 77 and 20K the wire has a tensile stren th
of 81, 140 and 192 kg/mm2, a notch touthness of 18.5.. 5.8 and 4.4 ka :nmi,
and a resistivity of 70, 59 and 56.10 ohm-cm, respectively. The critical
temperature of the wire is 9.7K and the critical magnetic field at 4.2K is

ABSTRACT: Information is presented on the technology and results of
tests on argon-are welding with tungsten electrodes of
aluminumUs-bara. The following conclusions are made:
the described method can be used for welding in bottom,
vertical and ove:rhead position and has marked advantages
over gas-welding, i.e. there is no need of flux, no sub-
sequent cleaning of the joint, better quality of the seams,
higher efficiency and reduced cost of work. There are
2 tables.

ABSTRACT: It is not easy to make joints in aluminium busbars.
Special fluxes have to be used for acetylene welding of aluminium
and it is very difficult to employ electric are welding with
carbon or metal electrodes. One of the best methods is that
of welding under a protective layer of argon gas. Argon-are
welding uses no flux and can be done with tungsten electrodes
that do not melt or with electrodes of other metals that do.
Tests were made on aluminium channels, sizes 12 and 17, with
wall thicknesses of 6 and 8 mm, respectively, using tungsten
electrodes and depositing aluminium wire. An a.c. welding set
was used having the circuit shown in Fig.l. An a.c. welding
set is simpler than d.c. and has other advantages. An oscillator
in the a.c. circuit ensures stable burning. In preliminary
tests, it was difficult to achieve the necessary heatin.& because
of the high thermal conductivity of aluminium. The tests were
made on aluminium, channels in all positions, up, down and
horizontal. The external appearance of welded joints made in

the various positions are shown in Fig.2. Specimen joints were-
made to standard rOCT-6996-54~ for testing in tension, in
bending and for hardness tests. The results are given in Table
1 and the appearance of the specimens after tensile tests is 0
shown in Fig.3. All the specimens for bending withstood 180
bonds, as shown in Hig.4. The Brinell hardness of the weld
and basic metal was about the same. Macro- and micro-examin-
ation of the joints revealed no defects in the metal. The
method of argon-are welding is recommended for aluminium. bus-
bars. Engineers I.n. Bondin, B.G. Yefstaflyev and B.A.
Rabotnikov participated in the work.
There are 2 tables, 5 gigures and 2 Russian references.

ABSTRACT: Using testing devices for determining tensile or compressive strength
which were modified for high temperatures, the authors studied the mechanical
properties of various types of graphite and of niobium and zirconium carbides In,
the temperature-range from normal up to 3200C. The principal characteristics' of
the modified testing devices viere uniform heat distribution In the specimenil at
very high temperAtures and the ability to measure very small deformations over a
wide temperature range. The specimens were heated directly or Indirectly by

electric current; when small spec imens were tested for compressive strength, they
were heated both directly and Indirectly with a graphite thermoisolated heater.
Stress was measured with a dynamometer, changes in load being recorded with.time,
while the deformation produced was recorded photographically. The data obtained
were then,plotted, yleldirg curves from which the tensile strength and modulus of
elasticity could be calculated. The relationship between elasticity and tempera-
ture for graphite, and the effect of the addition of pyrolytic carbon, arel shown
in ~ig. I of the Enclosure, while Fig. 2 shows the relationship between tempera-
ture and mechanical properties for niobium carbide. At normal temperatures,
some specimens of nlobium and'zirconium carbides had a compressive Strength of
more than 30,000 kg/cm2 and a modulus of elasticity in the range of 10 million
At 2500C. the compressive strength and elasticity of these materials were
kg/cm2
equal to tfiat of graphite. However, the mechanical properties of nioblum carbide
at high temperatures depend on its structure: specimens with high porosity.show-
ed much lower compressive strength and elasticity at high temperatures thanspeci-
mens with,lower porosity. The general set-up for determining compression strength
Is shown in-Fig. 3 of the Enclosure. Orig. art. has: 3 illustrations and 2

(I) upon heating C6H5CH2Cl (II) in HOCH2CH2 2~ (II ) In Thi
presence of metal chlorides (MC). During react ons of metal-
organic compounds (MOC) with iuftdrous MC in a III medium,
amongst other products, I Is formed; in a medium of dioxane
(IV) the reaction product is II; the formation of I in a III
medium depends on the catalytic action of MC. The possibility
Is shown of this catalytic reaction extending to the formation
of other mixed benzyl ethers. 117 mmole of 11, 10 g of III ANI
13 mole of anhydrous CuCl are boiled for 1 hour, the fil4-ate
is distilled with steam, & distillate is extracted with ether,,

ABSTRACTi The glass electrodes described axe manufactured from lithium-
containing glass with an addition of Lanthantm 9M cesium in
aooordsuce with a description previously given (Ref 1). The tech-
nique of manufacture is described and -two varieties of the shape
of the electrodes are mentioned. Chlorination of the silver
electrode is carried out by anode polari ation in O.In hydrochlor-
io acid, whereas vaporization of the electrode liquid is prevented
by the malting-on of uplatinite" as a hermetically tight seal. The
characteristic of the glass eleotrade is shown by a diagram for
temperatures of 25, 60 am 950 0; an analogy between the glass
electrode and the hydrogen electrode for the range of from pH 0.5
to 12-5 is observed. The eleotroaez aro resistant against a longer
heating in acid or alkaline solutions without changing their

ABSTRACT: Sodium glass electrodes, such as ED-1 and :ES-2, have too
low an incidence of applicability. The author: investigated
lithium glass Nr.. 490,491, and 494 (composition in table 1)
at temperatures between 170 and 950 and in the pH range I to.
12,5. The glasses were produced by the collaborators of the -
Glass Institute G.S.Bogdanova and Ye.Orlova. The experimental
arrangement is shown in figure 1; the electronic potentiometer
2P DV--53 was used in measurements. The solutions used
were H2so 41 HC" citraterphosphate buffer solution, alkali-
borate, and alkali solutions. The pH level was controlled~
using a'hydrogen electrode. Table 2 summarizes the experimental
results. The potential assymmetry tLnd the resistance of the
electrodes were also measured (Figs 3,4,5, and 6). These
Card 1/2 properties do not change if the lanthanum-cesium ratio

The Electrode Properties of Lithium Glass SOY/76-32-9-3/46
in the glass is raised from 1 to 1,67. The increase in
the curve characteristic of the electrodes becomes 16sa at
higher temperatures and at pH values above 9. This results
from a change in the true pH value of the solutions. There
are 6 figures, 2 tables, and 2 references, 'I of which is

ABSTRACT: The possibilities for the application of copper for the
production of internal electrodes are investigated. The
principal demand made on an internal electrode is that tho
potential jump at the boundary glase(metal)-solution must
remain constant. This is the case if the metal is not dis-
solved at all or very slowly, i.e. the concentration of the
ions which determine the potential, remains constant. There-
fore, the glass electrode was filled with a 0.5n copper
sulphate solution2 which was acidulated with sulphurio acid
to a 0.2n concentration, because, in the absence of an oxida-
tion medium, copper dissolves very slowly in sulphuric acid.
Oxygen was carefully removed from the glass electrode and the
latter was hermetically closed. The copper electrodes were
made by post-treatment from an insulated copper wire (dia-
meter 0-5 ma), such as is used for transformer windings. The
Card 1/2 glass electrodes produced (Fig) are tested for some time by

means of a potentiometer of the type LP-5 and after having
been kept in O.In hydrochloric acid. After storage at room
temperature for 9 months, no variation of zero (Table) was
found to have occurred. Slight variations occur in the case
of heating, but this is characteristic of the lithium glass
from which the glass electrodes were made (Table). There are
I figure and 1 table.

TITLE: Laboratory Unit for Measuring the pH of Solutions
With a Glass Electrode
PERIODICAL: Zavodskaya laboratoriyat 1959P Vol 25, Nr 10, p-1269 (USSR)
ABSTRACT: The laboratory pH-meters of the type LP-5 with glass electrode
produced by the home industry use up much of the solution to
be Investigated, because the electrode must be washed out
several times with the solution. A pH-meter (Pig) with a glass
electrode was constructed, for the application of which a
sample quantity of 0-05-0-10 ml suffices. The glass electrode
is made from lithium glass (Ref 1). pH-measurement may be
carried out by means of a potentiometer of the type LP-5; it
't is, however, necessary to pay attention to reading off the
values, because there is a difference between the"zercFof the
given electrodes and of thos6 which are used in the pH-meter
Mookip. From the description of the pH-meter it follows that
the glass electrode and the calomel standard electrode are
fastened to a lamella of organicglass, and that a narroj
capillary (1.5-2.0 mm diameter) extends from the lower ,;n4
Card 112 of the calomel electrode to a point 2 mm below the neck of

of a filter paper tampoon. The capillary ia filled with a
saturated solution and arystals of potebsima-tdoride. For the
pH-measurement of small volumes of liquids a glass cup, made
from a glass tube having a diameter that is 0.1-0.2 mm grea3er
than.that of the glass electrode sphere, is used. If the
pff-meter is not in use, the electrodes are stored in a metal
cup which is filled with a saturated-potassium chloride
solution, and whichg in its interior, is lined with organic
glass; the metal cup is fixed onto the pH-meter. There are
1 figiAve and 1,Soviet reference.

ABSTRACT: The author investigated the Influence of 7-rays on -
electrode properties, of' glass used for glass electrode
production. A Nt- 25 glass tube 12 rmn In dIam held a
glass spheve made of lithium electroJe glass of
following constitution (in molar percent): LI 20--.27;
Cs20 La20 3, Sio 2 - 6,(. The author pt,oceeded
to test three most sensitive characteristics of the
electrodes, the sensitivity gradient, the potential of
a symmetry ---,nd the resistance. The Inslde of the elec-
trodes weve filled with a 0.1 N solution of hydrochl:oric
acid. The measurements of the glaos electrodes In
standavd buffer solutions were done with respect to
Cavd 1/11 saturated calomel electrode held at the same temperature.

us ed was 90 v. Resistance measurements were of + 1%
accuracy. All cylindrical parts of the electrodes
were covered by vaseline to make them nonwetting. The
electrodes were exposed to -radiations from a
Co 6o source equivalent to 20.000 gm, equiv. Ra. Electrode
spheres were located 7 cm from the center of the source,
and the exposure.lasted 48 hr. The integral Irradiation
dose was 25 Mr. After exposure the electrodes became
dark brown. The sensitivity gradient was measured to
be 58.o + 0.3 mv/pH at 21 0 and remained unchanged
during t'ffe -exposure, after correcting experimental
values for a slight temperature variation. The resis-
tance of lithium glass remained also constant within the
experimental error before and after exposure. The
change of the.potential of asymmetry of the electrodes
was on the average 3 mv. The author concludes that
this shows that the lithium glass electrodes can be
used for pH measuremenus of solutions containing a
Card 3/4 high percentage of -active isotopes. There are I
