TIMt The ratio of the carbon and vanadium content in high-speed steels
PERIODICALi Refdrativnyy zhurnal. Metallurgiya, no. 1, 1962, 39, abstract 11266
(V.sb. "Stai'", Moscow, Metallurgizdat, 1961, 469 - 477)
TEXT: In high-speed C-V steels, used In practice, the following relation
between the C and V content is observed: C - 0.7 + 0.2(V - 1). In this case,
extended holding times are required for heating for quenching, to.assure. carbide
dissolving and high red-hardness; holding time attains up to 10 see/mm or, ac-
c6rding to some recommendations, up to 2D see/mm of the work piece thickness
Wiameter). This causes growth of austenite grains in the carbide and the separa-
tion of carbide along the grain boundaries, simultaneously rl~ducing strength and
ductility. Investigations were made with 2CY*heats with a large range of alloying
element contents (0.9 - 1.2 - 5.0% V) and it was established that the
best technological properties, which make it possible to-reduce holding down to
3 - 4 sec/mm, are attained at a C content raised.by 0.2 - 0.3%. or by reducing V
correspondingly -to relation C 0.9 + 0.25(V-1). Grade P18403MM (Rl8F3XBM)

TITM: On increasing the ch iiical stability of diffusion of
chromated steel. (Povysheniye Iffiimicheskoy stoykosti
diffuzionno-khromirovannoy stali).
PERIODICAL: Metallovedeniye i Obrabotka Metallov, 1958, No-3,
pp. 61-62 (USSR)
ABSTRACT: One of the drawbacks of chromating is the porosity
of the diffusion layer, which is observed in some cases,
and which brings about pitting corrosion of components
operating inside aggressive media. At the Leningrad
Polytechnical Institute (Leningradskiy Folitekhnicheskiy
Institut) experiments were carried out on increasing the
chemical stability and the surface hardness of diffusion
chromated layers by additional cementation by means of
carburisation. Diffusion chromating was effected on
low carbon steel 112011 and armco iron specimens inside a
"metalliser" consisting of 50% low carbon ferroc.hroEium,
45% aluminium oxide and 5% ammonium muriate at 1200 C
for a duration 8f eight hours. The carburisation was
effected at 930 C for four hours in a carburiser produced
by the Bondyuzhskiy Works. A reproduced micro-photo
Card 113 shows the micro-structure of thelayer which was

chromated and then carburised as revealed by etching with
a 10016' solution of nitric acid and alcohol; at the surface
of the chromium-cemented layer, a carbide crust of about
0.1 mm thickness, which is not affected by the etching,
can be observed. The results of determining tile hardness
and the corrosion stability after chromating and chromium-
cementation are entered in a table which gives the
hardness and the chemical stability of carburised and
non-carburised chromated specimens. Observation of the
corrosion behaviour of chromated and chromated + carburised
specimens in sea-water have shown that pitting corrosion
can be observed after three days on chromated specimens,
whilst no corrosion was observed even after ten days on
specimens which were chromated and then case hardened.
Formation of a layer of chromium carbides during case
hardening of chrom,ated specimens brings about En increase
in the density of the chromated layer and an increase of
its corrosion stability. This is attributed to the fact
that during cementation of chromated specimens a
compression takes place of the surface crust due to
Card 2/3 increase in volume during the carbide formation which

steel.
brings about welding of the Bores in the temperature
range of case hardening (930 C). Furthermore, during
hardening of chromated steel, the chromium
concentration at the surface of the chromated layer
increases owing to counter diffusion of.atoms of
chromium towards the diffusion front of the carbon and
this also results in an increase of the chemical stability
of chromated specimens.
There are 1 figure and 1 table.

TITLE: Mechanical properties of a zobalt vanadium high-,speed
cutting steel with a high xungstei_ content
PERIODICAL: Izvestiya vysshikh uchebnykh zavedcjn,~.y, Chernaya
metallurgiya, noo-4, 1961, pp-119-125 ~
TEXT., The object of the present investigation was to atudy
the effect of various heat treatments on the transverse bending
strength, impact strength, and impact fatigue strength of a high-
speed cutting steel PIF~Iti4K,77` (Rl8F4K8M),, containing 1,25-1.4% C'
4.4-5% Cr, 15.5-17% W, 3.2-3A% V, 7.,5.-8.5% co and 1.2-1.5% Mo~
The impact tests were carried out on unnotched bars, pure bending
impact load (30 kg cm) was used in fatigue tests on 12 min diameter
cylindrical specimens. The results c_an be summarized as followsa
1) After annealing at 850'C.. the mechanical properties can be
improved by a supplementary treatment, consisting of heating for
1 hour at 7200C followed by oil.-quench-ing. Thistreatment causes
an insignificant decrease In hardness (from 277 to 269 Brinell)
and a smail increase in bending strength, 11~'~l (from 150 to
156 kg/mm but consIderably improves the impa4c~t strength, at k

(from 2.0 to 5.6 kgm/cm 2 ). 2) The supplementary treatment Is
beneficial also in cases when the steel is subsequently hardened
and tempered. Steel, hardened (by quenching from 1240%) and
given three tempering treatments each of I hour duratir) at
560GC, has OvQ, (abend)= 184 kg/mm and a k = 0.95 h9m/cm , the
''corresponding figures for specimens preliminarily tempered at
2
720*C being 188 kg/mtn2 and 1.3 kgm/cm . 3) The steel R18F4K8M
.is prone to temper brittleness both in the annealed and hardened
condition. To avoid this brittl6ness (closely associated iiith
precipitation hardening), components should be oil-quenched from
the tempering temperature. The effect of cooling rate after
tempering is shown in Fig.2; specimens were annealed at 850'~C,
oil-quenched from 1210, 1240 and 1270*C, and tempered twice for,
.1 hour at 560% and once for 2 hours at 600*C~ The blocks in
each of the three groups relate (from left to right) to specimens

from loamy chernozem soil of the Orlov oblast' and from gray forest
argillaceous soil of the Yaroslav oblast' revealed a striking si-

is noted that "zhuravchiki" vere formed under the influence of
soil-formative processes. The formation of "zhuravehiki" in dif-

In the authors' opinion, treatment of syphilis with a conbination of neosalvarsan.
bismuth and penicillin produces much better therapeutic results.than treatment
with penicillin alone. Heavy metals and arsenobenzol do not reduce the effect of
penicillin. Penicillin decreases the toxicity of arsenobenzol and bismuth (experi-
ments In mice). The bactericidal activity of human serum is enhanced by peniciffin.
This increase is promoted by simultaneous administrationof neosalvarsan.

ABSTRACT In industrial-scale production of nucleic
acid from bakers' yeast, for the preparation "Nuklevazan"
which exhibits a hypotensive action, a siphon-centrifuge
has been used in.the step of separation of extract from
yeast hydrolysate. Separation of inert materials from the
thickened extract was effected by mixing the latter with
50% alcohol in alkaline medilam (pH 8); this leaves the
N-la-salt of nucleic acid in solution, while the precipitate
of proteins is separated by centrufuging and is discarded.
Preservation of the finished reparation is effected by
adding to It 20k alcohol (95. ~ and 5$ glycerol.
