ABSTRACT: On the basis of certain considerations it is assumed that
in the series H 2 -1, N2 -.%. co2as carrier gas (CG) a -clurxing
of the chromatogram bands at the absorbed substance becomes
stronger with respect to a finiteness of kinetics, while
blurring becomes lower with longitudinal diffusL----a. Here,
an investigation is made of the influence exerted by these
Card 1/3 factors on the band blurring (BB); the above mentioned carrier

gases are applied in this connection. The adsorbent used
was pre-treated silica gel MSM. The adsorption isotherms
and adsorption heats of n-butane (I) in 11 2' N2 and C02 were
determined according to the dynamic method (Ref 10) in an
appropriate apparatus (Fig 1). The obtained adsorption iso-
therms of in H , N and C02 obey the Langmuir equation
(Figs 2, 3~1.)The aisQtion coefficients and values of the
maximum adsorption of (I) in H 2p N2and C02 were derived
from the diagrams (Table 1~. Experimental results showed
that the nature of the (CG considerably influences the
above mentioned factors. The numerical values obtained con-
cerning the effective coefficients of the longitudinal dif-
fusion (Table 2) with (CG) gas flow rates of 12 - 100 cm/min,
as well as the obtained elution- and chromatographic curves
of the gaseous hydrocarbons point to a uicker and more

on the (BS) is observable. The last mentioned factors are
given for various gas flow rates and the individual (GC) are
mentioned (Table 3). Finally, gratitude is expressed to
Professor A. A. Zhukhovitskiy. There are 6 figures, 3 tables,
and 20 references2 8 of which are Soviet.

TEXT: The authors investigated the effect of the structure of silica
gel on the separation of gaseous hydrocarbons, thus evaluating the
efficiency of separation by the difference in the adsorption heats of
the components and the criteria of separation K1 and K2 (Ref. 5). A
pyrolytio gas (10% H2, 40% CH41 12% C2H6, 20% C2H4' 2% C3H81 12% C3H6,
2% C4HIO, and 3% C4H8) was investigated, however, only the separation
of the pair C2H6 - C2H4 was examined. Z. P. Kuznetsova, Laboratory

Assistant, participated in the experiments. A device described in
Ref. 6 was used, which renders chromathermographic and elution tests
possible, Two series of silica gel served as samples; one was prepared
by I. Ye. Neymark's method, and the other was treated with hydrochloric
acid and aftertreated with 0.1 N of KOH. In addition to the latter
(MSM) silica gels, also non-treated MCK(MSK) and I-4'_!1-(MSM) silica-gel
samples were examined. The authors determined the structural charac-
teristics (Ta!~Ies 1p2) by a method of I, A. Lipkind. The authors found
that a better separation can be obtained by increasing the specific
surface and reducing the pore diameter of the silica gel. A comparison
of the adsorption isothermal line of butane (Figs. 192) and the
adsorption coefficients G derived therefromg the maximum adsorption z,
and the ratio G/z reveals that less convex adsorption isothermal lines
were obtained on MCPI(MSM) silica gel treated with HC1 and aftertreated

with 0.1 N of KOH. This treatment lovers the adsorptive capacity of
silica gel (Table 3) since the pore diameter is enlarged and the
specific surface reduced. Thus, the authors succeeded in avoiding a
polymerization of unsaturated hydrocarbons (propylene and butylene)
which, however, takes place with untreated silica gel. Table 4 lists the
values of &G and K1 for ethane and ethylene of the various silica-gel
samples. Finally, the authors thank Professor A, A.,Zhiikhovitskiv for
his interest in the present investigation. There are 4 figures, 4 tables,
and 10 references; 7 Spviet, 1 German, 1 Czechp and 1 American.

TITLE: The behaviour of coke at high temperatures.
(Povedeniye koksa pri vysokikh temperaturakh),
PERIODICAL: "Koks i Khimiaall (Coke and Chemistry), 1957, No.3,
pp.24-29 (U.S.S.R.)
ABSTRACT: The literature dealing with chanGes of mechanical
properties of coke heated to high temperabures is
surveyed. It is concluded from -this survey that on
secondary heating to high temperatures the strength
of coke decreases. An experimental investigation of
the following problems was carried out: changes in the
degree of fissuring during secondary heating of coke;
thermomechanical strength of coke during the static
test under pressure and thermomechanical strength of
coke during a dynamic test. It was shown that under
the influence of heating the structure and texture of
coke changes. These changes undoubtedly must lead to
a decrease in its mechanical strength. Changes in the
thermomechanical 0strength of coke appears at tempera-
tures above 1000 C. A sharp increase in the formation
of small fractions (below 250mm) takes place in the
temperature region 1200-1250 . It was found that coke

proportions of coal grains above 3 mm (8-14c). Methods
of coke testing at high temperatures used in these
investigations are described in some detail. There
are 2 tables, 7 fiGures and 16 Russian references.

PERIODICAL: Koks i Xhimiya, 1959. iyr 1, pp 21 - 24 (USSR)
ABSTRACTt Properties of oize fractions of coke: above 80 mm,
80-60 mm, 60-40 mm and 40,-25 mm were investigated.
Mechanical pro erties were tested by standard drum tests
(GOST 5953-5M, results are given in Table 1; coke
reactivity by reduction of carbon dioxide to monoxide
according to Ref 6; results - Table 2; the hardness of
the coke substance according to Ref ?i results - Table 3
and the degree of carbonisat-ion of the coke by measurements
of its electro-conductivity, according to Ref 8;
results - Table 4. It was found that the quality of blast-
furnace coke is determined by properties of its individual
fractions and is non-uniform not only in respect of size
fractJ.6n.s but also in respect of other properties
characterising these size fractions such as strength,

Fractions of Blast Furnace Coke
hardness, reactivity and the degree of carbonisation.
Differences in properties of the individual size fractions
of coke, while the quality of the coal blend remains con-
stant, are determined by thermal conditions of coking.
The most uniform in respect of all the properties tested
are size fractions 60-40 and 80-60 mm. SeDaration of
these most uniform fractions may secure th7e supply of
blast furnaces with the most uniform fuel. There are
4 tables and 8 Soviet references.

calculation is presented showing that a 10-day exposure for the.
purpose of obtaining an unmistakable spot in the emulsion will be
successful with a localized segment containing C14 of about 104

Radiographic Investigation of the Distribution of Carbon in Iron. Alloys
The nature of the interrelation between the distribution of C on the various
conditions of heat treatment and various contents of alloying substances is
established: a) if the percentage of alloying and carbide-forming elements and
C at a given temperature of heating does not exceed their saturation solubility
in Fe, then the G and the inclusions spread relatively uniformly throughout the
volume of the grain. The process of redistribution of C in the direction of en'
riching the grain boundaries is impaired; b) if the concentration of carbide
formers exceeds their maximum solubility in Fe, the grain boundaries will be-
come enriched by these elements, and consequently by C as well; c) if the
concentration of non- carbide -forming elements does not exceed their solubility
in Fe, they will undergo uniform distribution throughout the volume of the grain
and will facilitate an increase in C at the boundaries; d) if the concentration of
non-carbide -forming elements exceeds their solubility in Fe, the grain boundaries
will gain therein and will lose C. Bibliography: 26 references.

ABSTRACT: The problem of the distribution of alloying elements,
particularly of carbon in the microscopic zones of
a and y-solid solutions of ferrous alloys, has so far
not been solved satisfactorily from the experimental
point of view. The nonuniform distribution of individual
elements in the microstructure is considered as being of
decisive importance from the point of view of the
behaviour of metallic alloys. Kumerous metallurgists
accept the hypothesis of V. I. Arkharov who assumes that
in polycrystalline aggregates the Gibbs surface effect
extends to layers of a thickness of many atoms; according
to this hypothesis, the surface layers of a crystallite
are enriched by an admixture which is capable of reducing
its free energy and an over-concentration of the
admixture in the alloy is sufficient for forming such
Card 1/4 layers (Refs.1 and 2). In spite of satisfactory inter-

pretation by means of this hypothesis of a number of
phenomena taking place during heat treatment, this
hypothesis has not been experimentally confirmed.
Although mentioned by various authors, the nonwiiformity
of the distribution of individual elements inside the
austenite grains has not been confirmed by direct
experiments. In this paper the results are described
of investigations of the distribution of small quantities
of carbon in alloyed iron,effectij by means of auto-
radiography,using radio-active C as a tracer element.
The investigations were carried out on six types of
low carbon steels alloyed respectively with Ni, Cr,
Mol Mn and Sil the analyses of whiah are given in a
table, p.128. The radio-active 9 was introduced
by means of carburisation at 970 C with BaCO, without
addition of carbon and, therefore, the increage in the
carbon content above the initial value did not exceed
0.03 to 0.05%. The specimens were tr8ated so as to
obtain coarse grains (annealing at 970 C for 50 hours)
and to detect more clearly the distribution of the
Card 2/4 carbon inside the individual crystallites. The

exposures reproduced in the paper have been obtained
after various conditions of heat treatment i.e. in
the annealed state in 8he hardened state Nuenched in
water from 1200 L-~a 900 C respectively) and in the
tempered state. On the basis of the established
relations between the carbon distribution at various
heat treatment regimes and the contents of the above
mentioned eleirients the following can be assumed as
being generally valid:
1. If the concentration of the alloying elements in the
carbon at a given heating temperature does not exceed
the limit solubilities in the iron, the carbon and the
alloying elements will be distributed relatively
uniformly throughout the grain volume.
2, If the concentration of carbide forming elements at
a given heating temperature doe Itexceed. the limit
solubility in iron, the elemeM~ld ributed relatively
uniformly throughout the grain volume and thereby
will slow down the process of redistribution of carbon
(enrichment with carbon of the grain boundaries); if

the limit solubility at the 6iven temperature, the grain
boundaries vill become enriched with the respective
elements and thus also with carbon.
3. If the concentration of non-carbide forming elements
at a ~Siven tem-..-erature is below the limit solubility,
those olemonts will dis~ributo relativ,~ly uniformly
throughout the -rain volume which will brin- about a

ABSTRACT: In numerous papers the role of tho liquid bath on the
metallurgical reactions of weld joints is either not
considered at all or is considered as being insignificant,
since the temperature conditions in the weld bath are
assumed as being much less favourable for interaction
between the slag and the metal than in the are gap or
the ti p of the electrode. However the results of a
number of investigations (Refs-9-153 indicate that in
principle interaction between the slag and the metal is
possible in the weld pool in spite of the fact that
the metal in the bath is conserved in the liquid state
for only a very short time. In this paper some results
are given of investigations of the reaction ability in the
pool of the molt metalwhich were obtained by means of the

of this element into the slag was also investigated,
which permits establishing additional possibilities of
desulphuring of the weld joint of a metal during welding.
Furthermore, the possibility was investigated of the
development of reactions of transfer of sulphur from the
coating into the rod and vice versa at the melting end
of the electrode. The test conditions and the test
results are described. It was established that,during
manual welding,the weld pool does not play merely the
role of a mould in which the metal solidifies; there is
intensive interaction between the liquid metal of the
pool and the slag. The participation of the weld pool
in the interaction between the slag and the metal is of
considerable interest from the point of view of
elucidating the general relations governing metallurgical
reactions in the zone of electric arc welding; it was
established that,with increasing current intensity, the
role of the weld pool in the general process of inter-
action of the phases decreases somewhat,probably due to
increasing volumes of phases reacting in the pool. By
Card 2/3 means of the autoradiography method it was confirmed that

there is a possibility of reactions between the metal
and the slag developing directly on the electrode tip
prior to the molten drop tearing away from it; with
decreasing dimensions of the drops tearing off the
electrode, the intensity of interchange of sulphur
between the metal and the slag decreases.

In the present work this investigati 3n was performed by autoradio-
graphy and the radioactive isotope C 4. Low-carbon iron alloys were
treated,that is chromium,nickel,silicon- and molybdenum-alloys se-
parately. C14 was introduced into the alloys be "cementation"in the
environment of radioactive barium carbonate.Since no coal was added,
the carbon content did not exceed the already existing 0-03-0,05;/-'~'.

ABSTRACT: 'When the two latter metals are used as construction material, great
attention is paid to the problem of the distribution of H in them,
since it sharply reduces their plasticity and increases t?eir stress-
concentration index.. The current metallographic methods give no Como
plete conception of the true distribution of H2 in the alloysp Thereo
fore the experiment of the use of tritium (- dadjoactive R2-iaotope)
for this purpose comes at the right time. There exist no published
data on the possibility of this use. The chied difficulty to produce
radiograms with it lies in the small decomposition energy of this
isotope. In order to be able to act upon the photo-emulsions either
tritium with a very high specific activity has to be used or the alloy
card 1/4 to be investigated has to be saturated with tritium to the highest

possible concentration. The task of producing tritium-autoradiograms
of titanium and zirconium is facilitated by a high solubility of
H2 (e. g.*compared with steel) in these two metals. Quite distinct
radiograms of it were also obtained, when the samples of the metals
were saturated with a tritium-H2-mixture to a concentration of 700-1000
ml gas per loo g metal. The figures 1 - 3 show "negative" autoradio-
gram . their darker sections correspond to the higher concentration
of H2 and inversely. From the comparison of thia radiogram with an
optical-microphotograph of a titanium sample follows that the struc-
tural image in commercially pare titanium is connected with the occur-
rence of titanium hydrides. The position of the structural components
in titanium with a comparatively high content of H2 indicates a phase-
recrystallization-process according to the type of the Yfidmannstedt
-structure. This position of flie structural components, one of whom
(titanium hydride) is very brittle, must naturally lead to the inin
tially mentioned impairment of the plastic properties etc. Furthermore
from the stronger darkening of the photoemulsion in the places where
Card 2/4 eutectoid is deposited (H2-content near to 4oo/o) it may be seen that

thq solubility of H in the *(,-phase at room temperature is very
1 2
small. It is known, that the verification of this fact by means
of other methods is very diffidul-t. In the autoradiogram of zir-
conium (figure 3) the microstructural imago does not render the
distribution of the hydride-inclusions, as it was the case in titan
nium. A complete analogy of the systems Ti - H and Zr - H is appaw
rently completely lacking. The elaboration of the method of autora"
diograms with tritium made it possible to determine a number of imn
portant laws governing the distribution of H2 in titanium and zirco-
nium alloys which metallographically often remain invisible. By the
same method the distribution of H2 in titanium welding was investi-
gated and it was found that the H2-transition from the basic metal
into the metal of the weld seam takes place uniformly and without
any marked concentration of the hydride phase on the boundary of
fusion.
