Study on nitrogen in martensitic stainless steels

HTM Journal of Heat Treatment and Materials, 2011
Abstract Pressure metallurgy is a means of increasing the nitrogen content and thereby the resistance of stainless martensitic steels to pitting corrosion. The present study on their constitution and heat treatment reveals that even at normal pressure more nitrogen is dissolved in the melt if ...

Residual austenite in martensitic stainless steels

Metal Science and Heat Treatment, 1965
1. Martensitic chromium-nickel stainless steels quenched and then tempered at a low temperature contain a considerable amount of austenite which is transformed into martensite on cooling to −70°C. 2. The amount of residual austenite in these steels increases (up to 40–50%) if the steels are tempered at 350°C after quenching in warm oil ...

Nitrogen in martensitic stainless steels

Journal of Materials Processing Technology, 1995
The influence of nitrogen on austenite grain growth, chromium content in carbides and corrosion resistance have been studied in chromium steels and alloys containing of about 13% Cr. The results shows that the inhibiting effect of nitrogen on austenite grain growth is observed in steels and alloys saturated in nitrogen by several methods.

Martensitic Stainless Steels

2008
Abstract This chapter discusses the metallurgy, phase structure, thermal processing, and applications of martensitic stainless steels. The phenomenon of martensite formation is explained. A table listing the compositions of martensitic stainless steels is also presented.

The martensite transformation in stainless steel

The Philosophical Magazine: A Journal of Theoretical Experimental and Applied Physics, 1962
Abstract The nucleation of the low temperature h.c.p. ∊ and b.c.c. α phases produced by deformation in a 304 stainless steel has been studied by transmission electron microscopy. The ∊ phase has been found to be an intermediate phase in the nucleation of α martensite from the austenitic matrix.

Alloy softening in a martensitic stainless steel

physica status solidi (a), 2009
AbstractA study of the tensile flow behavior in the microstrain region of a martensitic stainless steel within the temperature range 77–273 K has been carried out. The ductility and work hardening in the low‐temperature region were found to be significantly larger than those of the ambient at temperatures where alloy softening was taking place. Thermal‐

Solidification mechanism of martensitic stainless steel

Iron and Steelmaking, 2001
AbstractIn an unidirectional solidification experiment, an 8 kg stainless steel ingot with the composition 0·25%C, 17%Cr, and 1%Mn was solidified under continuous casting conditions. The dwell time of primary cooling was varied, followed by secondary spray cooling.

Embrittlement of brazed martensitic stainless steel

Materials Science and Technology, 1998
AbstractBrazing of AISI 410 martensitic stainless steel (12%Cr ) with boron containing nickel based filler metal was observed to lead to two major embrittlement effects – temper embrittlement and brazement embrittlement. Temper embrittlement, resulting from slow cooling of the material after brazing, affects both the dimple rupture and final brittle ...

Development of low-activation martensitic stainless steels

Journal of Nuclear Materials, 1986
Abstract An evaluation has been made of the properties obtainable from elementally-substituted martensitic stainless steels, the objective being to achieve properties comparable with those of an established 12% CrMoVNb steel in a composition that would allow hands-on recycling after 100 y storage. Tungsten and increased contents of vanadium have been

The reversion of martensite to austenite in certain stainless steels

Journal of Materials Science, 1973
An investigation has been made of the reversion of martensite (α′) to austenite (γ) in two stainless steels (i) Fe-16 wt% Cr-12 wt% Ni (of low interstitial content) (ii) Fe-15 wt% Cr-8 1/2 wt% Ni-2 wt% Mo-0.09 wt% C. The alloys were refrigerated to produce ∼ 12 to 15% martensite (α′) and then heated for short times at various temperatures ranging from ...
