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 ...

Martensitic Stainless Steels

Abstract This article presents fractographs of martensitic stainless steels that failed by fatigue and stress-corrosion cracking. A sampling of fractographs in the article illustrate a 410 martensitic stainless steel heat shield from a turbine engine that failed in fatigue due to thermal cycling.

Heat Treating of Martensitic Stainless Steels

2014
Abstract Martensitic stainless steels are the least corrosion-resistant of all stainless alloys. The traditional martensitic stainless steels are iron/chromium/carbon alloys, sometimes with a small amount of nickel and/or molybdenum. This article provides an overview on the influences of the various possible alloying elements on the key ...

Magnetic Study of Martensitic Transformation of Stainless Steel

Journal of the Physical Society of Japan, 1966
Saturation magnetization and roll magnetic anisotropy were measured for several single- and poly-crystals of 18 Cr-12 Ni-70 Fe alloy as functions of roll reduction in various crystallographic directions. It was found that the saturation magnetization increases as the roll reduction does for a polycrystal, (001) [100], (001)[110] and (110)[1\bar10 ...

Corrosion of Martensitic Stainless Steel Weldments

2006
Abstract Martensitic stainless steels are essentially iron-chromium-carbon alloys that possess a body-centered tetragonal crystal structure (martensitic) in the hardened condition. Martensitic stainless steels are similar to plain carbon or low-alloy steels that are austenitized, hardened by quenching, and then tempered for increased ...

Selection of Wrought Martensitic Stainless Steels

1993
Abstract This article describes general welding characteristics such as weld microstructure and weldability. The correlations of preheating and postweld heat treatment practices with carbon contents and welding characteristics of martensitic stainless steels are reviewed. The article contains a table that lists the electrodes and welding
