TITLE: ' On the Influence of Boron,on theGrain Size of Steel

ABSTRACT: .Most authors arrive at the cone'lusion 'that the addition
of 0.001 to 0.005% boron increases the effective size
of the austen'ite grain and inereases its teadency to
growth. Vinarov, S.M. (Ref.3) points out the variable
influence of various quantities of boron on the grain
'
size,~ Corbett.
R-and Williams, A. (Iron AFe.JTo-1%1945)
expressed,the view,that addition of boron doer not brine;
about increase in the size of the austenite grain.. Very
little is published in literature on the influence of
boron.and of the conditions of prelLainary deoxidation
on the dimensions of the austenite grain, Kafedra
Idetallovedeniya ChPI (Metallurgy Chair of CNPI) and
Tsentrallnaya Laboratoriya ChKZ (Central Laboratory of
the ChKZ) carried out studies of the influence,of various
quantities of boron and of preliminary deoxidation with

Ca
d
1/3 ferrotitanium on the size of the austenite grain uhich is
r
. obtained in the case of,heating of boron containing steel.

On: the Influence of Boron on:the Grain Size of Steel 129-58-5-8/17
,A melt of the 'stoel L35 (R f-5) micro-allo7ed .,Ith boron,
has been cast andAnvestig4ted. The smeltinS was done
in a 6 ton electric are furnace with an-acidic botoia,
The.influence.of boron additions on-the austenite grain
size-was 'studied during fractional casting of melts with
various quantities of boron. After reachin~~ the desired-
chemical,composition the metal was tapped into a 5.5 ton
ladle. After.tapping off the slao, aluminiun, (0.8 kg per..
ton) and 18% ferrotitanium (2 kg per ton of metal) were
introduced. From the large ladle the metal was poured
into a smaller casting ladle of 600 kg, at the bottom
of which,ferrobo.ral was placedicontaining 6.75% B9
4.85% Sit 5048%~Al, 0 06% C, O.OLW10 S, rest Fe. Prior to
introducing boron into-the metal-in the small ladle,,
additional deoxidation was effected using 1 kS of aluminium
'per 1 ton of metal. From'the small ladle ingots weighing
60,kg were cast- The chemical*composition of one of the,
investigated meits is entered in Table 1. Details are
also given ofthe tests relating to the influence of
C preliminary deoxidation of boron containinG steels aith
.3ard 2/3 ferrotitanium. on the grain size of the austenite. The

On.the Influence of Boron.on the Grain Size of Steel 129-58-5-8/17,
results confirm the great influence of micro-additions of
boron on the growth of the grain size during heating of
cast and forged steel. The temperature of the beginning
of an appreciable growth of the austenite grain during
heating of boron containing steel can be increased by
preliminary deoxidation and degasification of steel,by
means of ferrotitanium. The.results confirm that-
deformation in.the hot state has an influence of lowering
the temperature threshold of the growth of the austenite
grain. The experiments have shown that a non-uniformity!
in the grain size is a characteristic feature of boron
containing steels particularly in the as-east state and
this is attributeA to the noa-uniform distribution of
small quantities of boron 'along the grain boundaries.
If it isnecessaryto ensure a fine grain structure, boron
containing,steel should contain residual titanium to be
introduced.after deoxidation with aluminium.

The specific rate of dissolution for iron in this'alloy is'also very low and

iron saturation intensity.in a Zn+O.Z%Al alloy is due to the low calorizing
tomporature, Than, the bath is quitehighly saturated with iron during,
calorising,of steel in aluminum and aluminum alloys.
Two refining methods were testeds settling and filtering. Both methods are
based on a reduction in the solubility of iron in aluminum and its alloys Uhan,
the temperature is reduced. During settling, excess iron ihich is separated
out in the form of abndiddes or sincates in precipitated to the bottom of the
vat due to its higher speoiflo gravity. In the case of filtering, these iron
compounds a" retained by the filter for the same reason, Pure aluminum and

ABSTRACT: ~stlgatlonthe.aurhor has developed a theory of
resonance scattering,of electromagnetic waves on a plasma perturbation with
an arbitrary distribution of electron den3ity. The paper successively
considers the.polarization effect In resonance scattering of electromagnetic
waves,.the cross section'of resonance scattering, the equation of low-
frequency oscillations and.resonance scattering of radio waves by the trails
.of artificial satellites. The,considered special cases of resonance
Acattering do notexclude different variations In the cross-sections
associated with the influence of the~earthls magnetic field# motion of a body
relative to the direction of the latter, influence of collisions betveen
particles an the perturbation.of the concentration of electronsg Ions and on the
effectiVe dimensions of the trail. IAllowance .for all these factors In . I
principle can be-made using the general expressions obtained on the basis
of the resonance theory developed. In this paper* The author thanks 'We S!
