ABSTRACT: The results are presented from a calculatioll of the
.electromagnetic mass differences of barions. ;`The authors began
with a model of "non-relativistic" quarks, assuming that they are'
~located in a state with full orbital momentum equal to zero and
that the electromagnetio mass differences of the barions result
!from differeneas in electromagnetic quark masses, coulomb Inter-
actions.between quarks,and Interactions between magnetic quark
moment s. Me autilors thank Y~~ for sending -a- prepri'nb' of his worlag; bind'
Ya. B. Zeltdovicb and I. Yu. Kobzarov for their valuable critique. Orig,. art.

2) Intermediate transformation stops when a certain
quantity of non-decomposed austenite still remains,
whereby the completeness of the transformation increases
with decreasino temperature;
3) Diffusion redistribution of carbon takes place during
intermediate annealingi
4) Decomposition of austenite in the intermediate range
as well as the penetration after completion of the
transformation leads to a decrease of the martensitic
point of the non-transformed austenite;
5) On changing over from the pearlitic to the intermediate
range, a break occurs in the continuity of the change of
the degree of dispersion, hardness and other properties
of the decomposition products;
6) In the decomposition products of the lower part of
the intermediate region existence of the tetragonal
a-phase is detected;
7) The products of decomposition of the upper Dart of the
intermediate range are most frequently "feather" shaped,
Card whilst the decomposition products of the lower part are

characterised by intra-crystalline fracture. The authors
attribute this ty-De of fracture to the features of the
structure of the products of intermediate transformation,
which are considered as being a eutectoidal mixture of the

associated with the proce-as of carbide formation in the

of cases, even before tempering, the presence of carbon

itself strongly after tempering.

Evaluation of the tendency to develop temper brittleness

authors arrived at the following conclusions:
1) A partial tra-nsfor-ti-lation of au-,tenite in the inter-
u
mediate range during hardeninS has practically no
influence on the character of separating out of the embritteling
intergranular phase during slow coolin- of the steel after
tempering;
2) the intergranular phase which separates out during slow
cooling of the steel after tempering shows less influence
on the embrittlement than the orientated acicul-a--

decomposition are present in the structure, the fracture
of the steel in the case of impact tests will proceed
along the grain even if the steel i,.,as cooled siowly afte-r
tempering and an embrittled phase separated out at the
grain boundaries;
3) with increasing temperature of the partial intermediate
transformation of austenite (during hardening) and
increasing quantities of the Droducts of this transfLorma-
tion, the critical temDeratures of brittleness increase
both in the case of rapid as well as in the case of slow

is more intensive than in the second and,as a result of
thatIthe critical brittleness temperatures are close to

with oxidation (addition of nitrite and nitrate sodium-
salts). It was established that the process of
oxidation in these media takes Diace in jumps whereby
a transition is observed from the lower oxide types
into higher types of oxides and, in addition to
oxidation, partial dissolution of the metal takes place.
An optimum composition of the medium has been worked out
and the treatment time was determined which would ensure
obtaining an oxide film uhich possesses the highest
protective capacity. In this case,treatment at 400 to
500 0 increases the resistance to corrosion six 'Uo
sevenfold com-Dared to untreated components and three
to gourfold in the case of a treatment ter-,Derature of
300 C. Oxidation also increases the wear resistance
of cutting tools. The currently applied treatment of
tools in a vapour at,,',iosphere can be substituted by
treatment in molten oxiding agents.

proportion of cutting -tools are scrapped due to cracks,
and not due to natural wear. Therefore, the mechanical
properties have been studied o-C the hi.-h speed steel R9
(static compression tests, bendinG and torsion tests,
determination of the impact strength and of the fatui~~ue
limit) after various hardening regimes: current type
hardening; eteD-wise hardening in a inedium at a termpera-
ture of 560 C (15 minutes); isothermal hardening 0
(Variant I) in a medium of a temperature of 250 to 2N C
(four hours); isothermal hardening in a medium at 560 0
(Varian8 II, three hours) and transfer into a medium at
250-260 C (three hours); combined isothermal hardening
and cooling in a medium of 250-260 C (f8ur hours) CD
followed by transfer to a medium of 560 ~ (three hours)
and cooling again in a medium of 250_260 C (three hours).
For all these variants the above treatmet was followed
by treble tempering for one hour at 560 C. The author

Variant 1. It was established that isothermal hardening
increases the service life of the cutting tool,
Main Results of the Conference, There was a discussion
relating to the theory of intermediate transformation,
the structure and the composition of the products of
intermediate transformation as a result of which certain
important problems were singled out for further investi-
gation in this field:
a) Investigation of the structure and mechanism of the
formation of the a-phase;
b) Investigation of the structure of the steel by
electron microscopic and phase analysis;
c) Investigation of the fine structure of the y-phase
(distortion of the crystal lattice, of the size of block-s.
etc.) in conjunction with incomplete transformation;
d) Study of the transformation of residual austen.ite

Intermediate Transformation of Austenite (Yaroslavl,)
The delegates of the conference pointed out the practical
value of thermo-kinetic diagrams for viork'inS out heat
treatment regimes of various components and the necessity
of more thorough investigations in various organisations.
It was pointed out that isothermal hardening is
successfully applied for increasing the structural
strength of important components in engineering and alsatlie
strength and service life of tools made of high speed
and other tool steels, It was also pointed out that
hardening in hot media has certain technological
advantages, e.g. reduction of the distortion and of the
residual stresses. shortening of the heat treatment
cycle, possibility of obtaining a bright and aii oxidised
surface, The necessity was stressed of wider utuilisation
of progressive methods of heat t-~?eatment,

conditions for 6 hours and then returned for a further -,, da3-s
in the humidity cabinet. The other test conditions that ivere

and unworked to ground and polished; also, the surface
condition should govern the kind and thickness of plating.
Some, but not-all, kinds of stainless steel are liable to
corrode if the surface is rough and electro-polishing is
recommended for such materials.
The formulation of-the chromate passivating-solution affected
the corrosion resistance of cadmium plating, the best
solution being 25 g sodium dichromate, 20 g sodium sulphate
and 20 ml nitric acid of s.g. 1.85. It was found beneficial
to cover cadmium and zinc plating with lacquer or mineral
oil. If flexible copper leads were plated with sufficient
copper silver or nickel to give protection, they became
I ID
stiff. Passivation with chromium anhydride was useful but
the best solution would be to plate the individual strands
before laying-up. Cadinnium-plated steel parts were not so

ABSTRACT: Apparatus of the type RARK, designed for the investi-
gation of drill holes in (extremely- inaccessible,. places
and of exploratory holes with small diameter, enables
one to make the measurements both with automatic and
with - semiautomatic logging stations. Demounted logging
installations may also be used. The single-channel
apparatU3 permits one to make both gamma logs and
neutron gamma logs with a three-core or a single-core
cable. The depth instrument withstands pressures up
to 200 kg/cm2 and temperatures up to 600. Its length

the stratosphere at a latitude of 51ON during 1957-1958. The general intensity
level in the stratosphere during IGY was considerably lower than the level mea-
sured during the preceding solar activity maximum (1947-1952). It is noted that
no marked Intensity changes were detected during chromospheric flares. A compa-
rison of stratospheric measurement data with measurements of' the neutron compo-

greater by 1.6+ 0.3 times than on the Earth's surface. There are 9 references.

with the equator of magnetic inclination (70 northern latitude). It is possible
that equator position depends on solar activity.
