ABSTRACT:
Lyubarskiy, Lyubehenko
et al (Ref 1,2) have suggested

that the apparently different effect
of residual

austenite in the carburized layer os steel on wear

resistance is due to differences in submicrostructure.

The present
authors suggest that other phases should also

be considered and give
the results of their experimental

study of the wear resistance,
submicrostructure and degree

of alloying of the phases in the
carburized layer of steel

containing different quantitiestof
residual austenite.

A carburized layer in 18 KhNVA14steel subjected
to various

heat treatments (tableT -was used, wear being determined

with the aid of radioactive iron and cobalt. The

radioactivity of
the lubricant was measured and the

autoradiography of the wear
products was effected. The

phases were

and (311) interference lines, respectively (Ref 7).
Results are tabulated for specimens heat treated in
various ways and before and after wear. The wear and
rates of wear are plotted against the logarithm of
testing time in Fig 1 for the different conditions.
Curves of microhardness against time for two of the
conditions are shown in Fig 2. The results show that
the cooling conditions after case-hardening affect wear
resistance greatly, eg a high resistance with the same
residual-austenite content by rapid cooling is obtained.
Friction conditions also affect wear resistance and during
friction the submicrostructure changes. It has previously
been shown (Ref 2) that cooling rate does not influence
carbide distribution with respect to depth but does affect
the degree of saturation of the carbide phase with
alloying elements, particularly chromium, and the authors
discuss these factors in relation to the present
investigation and the behaviour of different components
during wear. Their general conclusions are that the best
wear resistance surface can be obtained through a correct
Card 2/3 assessment of processes occurring in the active layer Ir

during friction. In the test procedure used (pure
sliding of the radioactive specimen over a standard disc,
or under conditions resembling gear meshing - Ref 6
high wear-resistance is obtained when there is a
considerable residual-austenite content in the carburized
layer in which the gamma- and alpha-phase crystals are in
the "un-work-hardened" and "work-hardened" states,
respectively. Professor L.S.Palatnik contributed valuable
advice in this work. There are 2 figures, I table and
15 Soviet references.

TITLED Substructure of the 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 and 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-deformal~ion of the crystal
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 definite depth (Ref.2 to 4).
The forms of heat treatment used in the investigation were those
adopted at many works but some experimental variants-were also
tried. Type 18XHBA (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 920"C followed by one of the following:
1) cooling in furnace at about 1~C/min, 2) as (1) but at 3*C/min;

with
liquid oxygen,,, 6) as (2) followed by double tempering at
650*C,
quenching from 810 and tempering at 15VC. Successive 0.1 to
0.2 mm thick layers were removed from the 4 x 8 x 15 min
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 gamnia-phase respe4~tively~'-
microhardness
was measured with a nt4T-3 (PMT-3) machtrie at a load of 50
g. The
carburized layer for all treatnient3 consisted of alpha-,
gamma-
and carbide-phases, The nature of microhardness (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 laver is obtained with rapid cooling, Fig.2 gives
corresponding curves for maximum relati-ve deformation of
the
alplia-phass 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 work hardening of the
alpha-phase.

The latter makes diP6action maxima so diffuse that reliable
block-~-size and deformation data cannot be obtained. The-vrork
hardening'of the gamnia-phase is less than that of the alpha and is
very sniall at "working" depthr, 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 investigaVon support the views of the
present authors (Ref.1,2 and 6) that rapid cooling from the
carburizing temperature produces a favourable forin 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 harderling'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-hardemd
layer of 18KhWA, 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 (f8r large machine elements -
case hardening
with additional oil hardening at 810 C; for small parts - case
hardening with

~im, V. A. Maly*sheva (V. A. Maly*shev Factory In Khar'kov). The
author points out
that methods of'thickness measurement by the use of radioactive
isotopes have many
;advantages over other methods, and lists 2snveral of these
advantages. The new In-
.strument uses the radioactive Isotope TI 0 as the source of beta
radiation. The
.energy of the beta rays is 0.77 Mev and the radioactivity of the
annular source Is
15 mlllicuries. This rather high source radioactivity was chosen to
make It possi-'
to measure the thickness of nickel-phosphorus platings on steel. The

TITLE: .6n--the ~effect of gases on the flotation properties

PERIODICAL: Izvestiya Akademii Nauk SSSR, Otdeleniye

ABSTRACT: In earlier work of the authors (Ref.1), it was
found that
barite maintains in a stable manner the initial flotation
ability in the process of long duration treatment of its
surface by nitrogen after preliminarily treating the
surface with oxygen. In contrast to this, fluorite is
capable of changing the flotation properties of the surface
by reducing the flotation activity in the case of inadequate
oxygen in the pulp and reaching a flot~Ltion effect which is
the higher the higher the concentration of the dissolved
oxygen in the liquid phase; correspondingly, the quantity
of oxygen adsorbed by the fluorite will change. After
removing the adsorbed oxygen from the surface of the
fluorite by appropriate treatment of the mineral and long
duration blowing of nitrogen through the pulp, the fluorite
loses to a considerable extent its flotation ability and
C .d 1/2the collector sticks to the mineral. In this paper

investigations are described which were effected on a Dre-
cision test set-up inside a hermetically sealed flotatlon
machine and it is stated that these confirm and supplement
views expressed earlier by the authors. The tests were
carried out on pure fluorite and barite; the mineral
charge consisted of 20 g of grain sizes of 0,10 to 0.074 mm
with a sodium oleate dosage of 50 g/ton. The flotation
was effected in a neutral medium. The information given
in this paper explains certain features of the flotation
behaviour of fluorite and barite and, particularly, the
differing hydration of their surface which is due to the
electrostatic energy of interaction of the rigid dipole
of -the water molecule with the ions of the lattice and is
determined by the degree of non-compensated electric
charges of the ions and the character of their distribution
at the crystal faces. The results described in this
paper indicate the possibility of obtaining and utilising
structural data for elucidating certain flotation
Card 2/2properties of minerals. There are 3 figures and 9
references,
8 of which are Slavic.

ABSTRACT: The Study of thejLnfluence of gases on thefloatability
of non-
sulfidic minerals made possible the determination of several ad-
sorption and floatation properties of fluorite and baryte, which
are caused by the effect of gases. A prolonged treatment with
nitrogen has no essential effect on baryte, which first was
sLibjected to a treatment with oxygen. The floatation activity
decreases on a oxygen lack. The mineral was prepared and float-
ated for the experiments in a current of argon and of nitrogen.
Ritrogen free from oxygen was employed for the experiments. The
experiments showed, that becaise of the floatation on a normal
concentration of oxygen 4ep of fluorite pass into the concen-
trate. Farther properties are enumerated. The floatation activity
of baryte depends only little on the concentration of orygen in
the solution, if only oxygen was adsorbed previously on the
Card 1/3 surface. On the contrary, the floatation properties of
fluorite
