Tribocorrosion Mechanisms of Martensitic Stainless Steels
HTM Journal of Heat Treatment and Materials, 2021AbstractIn the present study, the influence of the electrochemical potential on the tribocorrosion behavior of X20Cr13 in 0.15 molar NaCl-solution was investigated with the aid of a universal-tribometer under potentiostatic control. The resulting material loss was determined through laser confocal microscopy, while the morphology of the wear tracks and

Embrittlement of brazed martensitic stainless steel
Materials Science and Technology, 1998AbstractBrazing 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 ...

Residual austenite in martensitic stainless steels
Metal Science and Heat Treatment, 19651. 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 ...

The martensite transformation in stainless steel
Acta Metallurgica, 1963Abstract Thin films of Fe-18Cr-12Ni have been examined both in the fully austenitic condition and after partial transformation in the bulk to faulted h.c.p. (e) and to b.c.c. martensite (α′). The e appeared to be a consequence of α′ formation rather than a necessary intermediate stage in the transformation.

Nitrogen in martensitic stainless steels
Journal of Materials Processing Technology, 1995The 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.

Solidification mechanism of martensitic stainless steel
Iron and Steelmaking, 2001AbstractIn 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.

Study on nitrogen in martensitic stainless steels
HTM Journal of Heat Treatment and Materials, 2011Abstract 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 the carbon content ...

Tensile Properties of Martensitic Stainless Steel Weldments
Advanced Materials Research, 2007In this study, AISI 420 martensitic stainless steels were welded by GTAW (gas tungsten arc welding) using ER 316L consumables. Pure argon, argon + 25% He and argon + 5% N2 were used as shielding gases. The obtained results indicated that shielding gases have some effect on the properties of the martensitic stainless steel weldments.

Development of low-activation martensitic stainless steels
Journal of Nuclear Materials, 1986Abstract 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
