In some cases electron diffraction analysis of fine particles was
carried out directly at the surface of the metallographic
specimens. These investigations revealed several processes in
the structure, namely, precipitation of chromium carbides at the
grain boundaries, precipitation of fibrous titanium carbide,
precipitation of intermetallic compounds. Interesting recrystall-
ization phenomena were observed if ageing at 8000C extended over
a long period. A K-structure was detected by means of
differential thermal analysis. During the first period of the
precipitation hardening, when the hardness, strength and yield
point increase, no change can be detected in the structure even
by electron microscopes with a resolution power of about 100 A.
The main hardening effect is attributed to the precipitation of
the y9-phase - Ni3 (Al,Ti). It was found difficult i:o determine
the importance of Ti(C,N) precipitate in the hardening process
but no particular role is attributed to it. The hardening
process continues during operation and the maximum hardness is
achieved sooner or later, depending on the temperature and the
titanium content. In addition to the hardness, the strength and

yield point also increase. At an operating temperature of 650 cc
the steel under investigation maintains a maximum hardness,
strength and yield point without any appreciable change in the
elongation and contraction for over 10000 lu-s Fig.14 shows the

There is a slight drop in the impact strength, indicating
structural changes at this temperature (6500C). i.e. primarily
continuing precipitation at the grain boundaries. At higher
temperatures over-ageiing occurs which results in reduced
resistance to strain; at 7000C a drop in hardness occurred after
100 hours. Over-heating, following by precipitation hardening
without solution annealing, reduces the service life as compared
to material which has not been over-heated. The results lead to
the following conclusionst

Structural and mechanical tests indicate that hardening of this
steel is primarily due to precipitation of the y'-phase, the
composition of which is Ni (Ti,Al). The second intermetallic
phase I of the compositi;n Ni Ti appears in the structure
during the advanced stage of ove~-ageing and its occurrence does
not manifest itself on the curves expressing resistance to
deformation. In the early stages of precipitation, particles of
fibrous carbide appear, for instance, the carbonitride Ti(C,N)
which precipitates primarily in titanium enriched-zones. At the
grain boundaries local precipitation of the chromium carbide
Cr7C.5will occur. Tests with over-heated specimens again
confirmed the fact that high hardness of hardenable alloys does
not guarantee a high resistance to creep. Over-heated specimens,
which were again hardened without solution annealing, reached a
hardness equal to those of specimens which had been over-heated
but their creep strength was low, since,as a result of this
process,the solid solution matrix vras impoverished of its
hardening component. Due to its high structural stability, this
steel is suitable for components intended to operate at about
6500C. Acknowledgments are expressed to Engineer P. Schier,

TEXT: The influence of titanium and aluminwn additions on hardenable,
high-ten.perature, NiCr-base alloys vras studied to provide a better understanding
of the behavior at design operating conditions of currently used materials, and
to facilitate the development of new materials. Studied kere the AMIN and 40C
alloys in which the Ti and Al contents were varied. Optical and electron micros-
copy; X-ray and electron structural analyses; differential thermal analysis;
conductivity, volume and hardness measurements were employed. Results: The de-
composition of oversaturated Ni-base solid solutions occurs in two stages: In the
range of 100-3000C, the so-called low-temperature decomposition, characterized by
the formation of a superstructure, takes place; in the range of 600-7000C, there

occurs local prdcipitation of Cr7c 3' In the 35Nil5Gr alloy, fibrous carbanitride
Ti(NG) precipitates at 700-7500C. At higher temperatures, precipitation of the
cubic j"phase Ni3Al or Ni3(AlTi), and of the hexagonal.phase with the stoichio-
metric composition Ni Ti was found. The precipitation of these phases causes the
hardening of "L-,hC5e alloys, Depending on the Al content, the dphase may develop
in either globular or cubic shape. Discontinuousprecipitation was observed in
35Nil5Cr and 74Ni20Gr4Ti alloys. Under certain conditions the phase precipitates
in a lamellar form on the grain boundaries. This anomaly is referred to as the
matrix recrystallization. Its formation is strongly influenced by higher an-
nealing temperatures and prolonged holding at these temperatures. More complicated
conditions were found in alloys with lower (36%) Ni and higher (4%) 111 contents.
For the first time the presence of the sigma phase was proved in this alloy type.
This finding is of importance for future development of new alloys which will have
to be so designed as to avoid the sigma-phase formation especially by limiting the
K1 cont6nts. Also., a so far un1m6wn phase was observed. it was designated the N.
phase and its preliminary analysis was performed. There are 37 figures and .1

agehardenable high-temperature materials, type 35Ni-150r and Nimonic 80, indicate
that the hardening of these materials is connected with a precipitation of the y'

TITLE: Structural stability of austenitic.manganese-slecla
SOURCE: Kovove materialy, no. 6, 1965, 526-548
TOPIC TAGS: metal heat treatment, austenitic steel, manganese steel, carbide phase
ABSTRACT! Based an results of tests the authors offer the followivg conclusions.
The austenitic structure in modified Mn steels of the type investigated is less
stable than in steels of the classical type. The sustenite in manganese steels con-
taining more than 8% Mn remains stable up to -100C. It also remains stable after
plastic deformation and subsequent freezing over the entire temperature range
including deformation up to 30C and freezing down to -50C. Aside from phases formin
the decomposition product of austenite during isothermal annealing of classical man-
ganese, ferritic and bainitic reactions were fourd to take place. The regions and
boundaries of all phases were established. Classical and modified'steels show two
hardness peaks as a function of temperature and isothermal annealing. The second

peak has not been reported elsewhere. The region of the first hardness peak is
characterized by the precipitation of the carbide phase and the formation of.
pearlite or bainite. The region of high temperature maximilm is produced by martensite'
formed in specimens cooled down from the annealing temperature. The process taking
place during continuous Blow heating can be equated vith changes under isothermal
conditions. Thermal hysteresis increases with the rate of heating and with a lower
reaction temperature. The amount of transformed austenite is smaller with continuous
heating. Changes appearing in the solid solution during the initial stages of con-
tinuous heating can be related to the formation of atmospheres of interstitial atoms
on packing defects. This process precedes the precipitation of carbides. The

nd-itructure and properties of IiZi (W-Cr-V), 94-2, and
114-4 high-speed steels are discussed. Thermal treat-
ment, metallography, and the so-called 2nd hardness tire
described. In or 'der to study pptn. phenomena, x-ray
structure analyses of the iepd. carbides have been made and
investigated by electron microscopy. The quality of tool

steels Is mainly Influenced by the 5tructurc or the stec
its heat-treatment* The formation of cmarse carbide grains
with n9ahomogenous distribution njust be avoided, as it
-reduces considerably the toughness of the steel. The
-secondary hardness is caused by the decay of residual aus-

TEXTi The author considers phenomena caused by*the impact of Lunik II-on
the Moon. The probable depth of rocket penetratiorL into the lunar surface,layer
was calculated from the relations derived in artillery and experimental results
(0-05-0-10 m in rocks and _3-4.4 m in dust). The penetration time in the latter
case is 0.0027 see, in the case of rocks _' cdrrespcindingly less. The flume of
the crater and of the matter ejected by impact-is estiinated to be 270 , bUt
on assumption of an explosion of the fuel remains - up to 1,200 m3. The mean
'velocity of matter ejection is - 100 Oec., the rarige of ejection - up to 6,000

ABSTRACT: The experience of the Czechoslovak metalworking industry has shown that
dimensional accuracy is one of the greatest advantages of explosive forming. There-
fore, it, Is frequently used as a sizing process for pw-ts preformed by a conventional
method. .Such parts,after explosive sizing, require no additional sizing. Sometimes
,a reversed method is used, i.e., explosive forming is wed as a preforming process.
Generallyl explosive forming is used for parts which are either too large for avail-
able forming equipment or which have an intricate shape! (see Figure 1). Explosive
forming it regularly applied to plate or sheet parts 0.6-14 mm thick. Dies for
shallow parts, whose forming does not require very higb.pressures, are made from a
zinc-tin alloy; those.for parts formed under very high pressures are made from
carbon steels. Very large dies are made of cast iron. Water tanks are made of
plastic, steels or rubber.. Tanks should be'rested on an elastic base which absorbs

vibrations. A special explosive, SEKrEX lt has been developed for explosive forming
by the Synthesis Semtin plant. The explosive is wator repellent, detonates in a
layer 2 mm thick, and is available in foil form. No negative effects of explosive
forming on the properties of formed materials were observed. The Middle Czech
Mad*ie Building -.Plant in Letnany and the First Five--Year Plant in Kunovice are
among those using explosive forming. The ffe-e-e-a-rc-Friiii-itute of Hea Machine Ruild-
ing in Brno coordinates the research in explosive oming. Orig. art. has: I figure,
