ABSTRACT: The author states that the bolometer is being increas-
ingly used to.measure centimeter high frequency output.
As,the band of-the working frequencies is not sufficient-
ly wide'-for measuring ranges adequately, a simple method
has-been developed to improve this situation, using
quartz tubes. Tests show that quartz tubes widen the
band of working frequencies by 20-25%. F~.,rther resEa7ch
is now In-progress on using quartz and other dielectric
tubes to this end. There are 1 graph and 3 references,

ABSTRACT: In the report great -atten -t i on was paid to'the complet-ion of
the method of measuring magmetostriction. This problem is
without any doubt of great importance. In this connection the
results of measurement are given which were determined by
means of new tensiometers of thin films. Thin films of
Constantam and other substances were used as resistance
t*nsiometers; they were applied to the sample by evaporati~,n
in vacuum. The first experiments were carried out with ar

is in agreement with the second formula for even Akulov

TEXT3 'Wire-type resistance strain gauges were used for measuring Magneto-
striction. Layers of glue and the insulating support in the teiisiomete-s
restrict a further increase of measuring precision. The successful
application by the authors of film tensiometers for measuring the magre!
striction of nickel permitted to develop this method with reference tc
ferrites, thus making it possible to improve somewhat and simplify tne
design of film tensiometers. The finished strain gauges were sub.iected
to artificial aging, in order to stabilize the proverties- Maagneto-
striction was measured by G. P. Dlyakov's method, Data for the ferrite
samples NO. 7 and 170. 73 are mentioned next. The film tenniometers
operate stably even at comparatively great temperature fluctuations
Since the sensitive layer is applied directly to the ferrite surface

without glue and supports, errors which are observed in glued-on
tensiometers during heatting do not affect the precision of measurements
It became possible to study the temperature dependence of the magneto-
striction of ferrites, as the 'Layers of nichrome and some other alloys
show high stabilities up to 300-4000C. There are 7 references,; 5 Soviet

of magne"11-ontriction, the strain gauges were connected to one of the arms of
a d-c bridge circuit'.. A sensitive mirror galvanometer serves as indicator
in the bridge diagonal. The.:bridge was compensated without a magnetic
field. When the magnetic field was spplied, a change occurred in the
BDecimen dimensions and in the resistance of the strain gauge owing to

Graphs are presented showing the relative elongation of tested strips versus aging time

with specimens containing 7. 0% zinc, shrinkage was observed at both 140 and 160 C. The
maximal strengthening of the alloy due to aging coincided with the time of maximal
shrinknge, after which the length of the specimen practically returned to its initial value.
H! Particularly large shrinkage (0. 1%) was exhibited by alloys with Cr, Cu and 7. 0% Z n. For
parts in which distortion during the aging process is particularly undesirable, V95 alloy with

and of a monotonous character. Mith regard to the influence of repeated quenching, tests
were conducted with two groups of specimens. Tests with the first group, which was
annealed at 450 C for 48 hrs., showed that a slight elongation occurs after the first
quenching. During siibsequent aging, however, shrinkage takes place, and beginning with
the second cycle, the length of the specimens decreases monotonously. Tests with the sec-

ABSTRACT: As a. result of experimental verifIcation of the effect of S and Mn cor
tent of,cast iron and also.of the temperature of overheating and casting
of iron on the formation of subsurface" blisters, it ,vas found that
ters are formed beneath the crust whenever a certain critical value for
the product of [O/qMn]- [%S] is exceeded. The Mn content in cas! iron
which is to be enami~led should,not be much higher than the ratio
required for combining with S. To forestall the formation of blisters
underneath the crust it is- necessary to raise the casting temperature
of the metal. The author proposes a hypothesis that the formatior of
the flaw is associated with the reaction (at low temperatures) MnS 4

TITLE: The casting of parts of-corrosion-resistant
ferronickel-molybdepum alloys
PERIODICAL: Liteynoye proizvodstvo,-no. 2. 1960, c)-10
TEXT: The article contain.s the results of investigations
carried out by the author, engineet A. I. Budyayev and Candidate
of Technical Sciences G. L. Shvarts, to study the utilization of
the 3-04-64A (EI461L) f err onicke !-molybdenum alloy for castings of
complex configuration, particularly of machine parts of various
type for chemical machinery. The author points out that, although
higb-strength nickel-molybdenum alloys have been used for some
time (in the Soviet Union, the grades 9%41~ro (E3460) and HV,1,11)
(MO) abroad, the grades Hastalloy B, Bergite and others have
found the most widesDread utilization) no data on the casting
properties, casting and pouring conditions and on the techwology

a F content in the cast alloy, exceeding 6%. lowers the corrosior~

and annealedmaterial has Ia strength of ~6b'--z90 kg/mm2. Complete
annealing is effected at 11150-10800C with 20-90 minutes hold~nE,
depending on the component dimensions, and rapid cooling in air
GargOBize parts are cooled in water). Stabilizing annealing is
taking place at 1,050-1,0650C, with 2-4 hours holding anu cooling
in air, which increases the anti-corrosion properties of the al-
loy. To increase the hardness, the componepts are annealed at
745-7600C with 169 hours holding and cooling in air, which makes
the haxdneBs increase to RO 50 and improves the abrasion resist-
ance, while the corrosion resistance is lowered. The tests stiowed
that the machinability by cutting of the alloy corresponds to that
of stainless steel. The author points out that the most effective
way of welding the alloy is by the oxygen-acetylene process, since
it permits the preheating of the welding zone and thus prevepts
the formation of stresses and cracks in the components. Moreover,
he recommends the alloy to be smelted in induction, furnaces with
basic lining, using preferably no wast charge materials. The a).-
loy should be reduced with Mn and Si prior- to adding pure go, -whlie

the final reduction should be effected -with aluminum during the
tapping or in the ladle. The shrinkage coeTficient of the alloy
amounts to 2%. and it tends to form shrinkage cavities and pores.
Therefore, it is necessary to avoid abrupt changes in the wall
thickness of the casting and metal accumulation in individual as-
semblies. To avoid blowholes in the casting, the molding sand
shculd have a Bufficient surface strength and should contain a
sufficient amount of binder. There axe 2 figures and 15 refer-
