TEXT: The authors Investigated the criteria of metal interaction during
dry friction, the metal substructure and its changes during the friction process.
In their conclusions they point out that the resistance to wear of-a friction
couple of metals Is determined by a combination of the structure and a number,of
properties: high compression, bending and shear resistance, a combination of
high hardness and ductility, stability of mechanical properties at high tempera-
tures and pressures, high heat conductivity and corrosion resistance.

TITLE., Substructure of tile Carburized Layer
PERIODICAL. Fizika metallov i metallovedeniye, 1961, Vol.11, No.2,
pp~247-251
TEXT. The authors give results of an experimental study of the
phase composition atid substructure of phases at various depths of
carburized layer. The substructure of a phase is represented by
the dimensions and disorientations of mosaic blocks and the size,
and nature of the change of micro-deformarion of the cryBtal
lattice with distance, The resistance to wear of the layer depends
on both composition and substructure but published work on
substructure-has been limited to some definitle depth (Ref.2 to 4).
The forms of heat treatment used Ln the investigation were those
adopted at many works but some experimental variants were also
tried, Type i8XHBA (18KhNVA), used for important parts of
machines, was subjected to arburization to a depth of 1.7 to 1.9mm
with a solid carburizer at 9WC folLowed by one of the following:
1) cooling in furnace at about ltC/min, 2) as (1) but at 30C/min;

3) oil quenching j 4) as (3) fonoweti by oil quenching from 810"C
and tempering at 1500C, 5) as (4) but followed by treatment with
liquid oxygen~ 6) as (2) followed by double tempering at 6500C,
quenching from 810 and tempering at 150"C. Successive 0.1 to
0.2 mm thick layers were removed from the 4 x 8 x 15 mm specimens.
At each depth, X-ray diffraction patterns were taken with iron
radiation in a Debye camera, the (211) and (311) lines being
focused for alpha- and gamma-phase respec;tively~ microhardness
was measured with a nMT-3 (PMr-3) machine at a load of 50 9. The
carburized layer for all treatments consisted of alpha-, gamma-
and carbide-phases, The nature of inicroliardness (kg/mm2) changes
with depth (hundredths of cm) is shown in Fig.1 in which the
curve numbers correspond to the above treatment numbers: the
least difference between the surface and deeper zone of the
carburized layer is obtained with rapid cooling, Fig.2 gives
corresponding curves for maximum relative deformation of the
alpha-phase crystal lattice and Fig.3 those of alpha-phase mosaic
block size, Treatment 6 gives least block size over the greater
part of the layer and intensive world hardening of the alpha-phase.

The 'Latter makes diffraction maxima so diffuse that reliable
block-size and deformation data cannot be obtained. The-work
hardening'of the ga=Aia-phase is less than.that of the alpha and is
i very small at "working" depths of the carburized layer when
quenching from the carburIzation temperature is carried out. This'
is in line with the observation of A.P.Lyubchenko and others
(Ref.1,2) that such quenching increases resistance to wear compared
with that obtained with treatment 6 (which is used in practice).
The results of the present investigation support the views of the
present authors (Ref.1,2 and 6) that rapid cooling from the
carburizing temperature produces a favourable form of substructure
of carburized-layer phases. Slow cooling after carburization to
a considerable extent exhausts the possibilities of good wear
resistance even before the part is installed because of the high
degree of phase work hardening'which the heat treatment produces
over the whole depth of the carburized layer. There are 3 figures,
2 tables and 7 Soviet references.

TEXT- The structure and physico-mechanical properties of the case-harderned
layer of 18KhNVA, 20X2H4A (2OKh2N4A) and other steels were Investigated from the
viepoint of the chemical heat treatment. The heat treatment conditions differ
by the speed of cooling after case hardening. The speed of cooling after case
hardening affects the phase composition, the substructure of phases and their
saturation with alloying components, which in its turn affects the wear resist-
ance of the case hardened layer. Compared with the conditions adopted at the
plant, the recommended conditions (f'Qr large machine elements - case hardening
with additional oil hardening at 81OuC; for small parts - case hardening with

the t'luc tun t ions, appeared to be negligible. This is contrary to
tile fin(jingS of K.P. Bunin and Ya.M. ~:alinochka that the effect of
spheroidimerm was to equalise the inter- and trans -crystalline
mobilities of the Fe atoms. The experimental and published results
show that the effect of Cc, mg, etc. on the graphite 'in cast iron
is not related to the kinetics of self-diffulsion and it is
probable that the surface active T)ropertie8'of the spheroidiser
are responsible for spl,"roidisation. The electron orbits of
additions appear to influence the shape of the graphite particles,
as is seen by comparing the electron structures of spheroidising
grents (Li, Nat Mg, K, Ca, Sr, Ba, Cc) with those of de-
spheroidising agents (Ti, Cu, Sb, Fb, Bi). Inconsistencies in the
behaviour of added elements on the structure of the graphite
appearm to be due to changes in electron configuration caused by
interaction with impurities,in the iron. Spheroidisation can also.
be achieved by additions which ensure the required electron
cotifigtiration when absorbed on the graphite.
