Activation Response of Martensitic Steels

Journal of Fusion Energy, 1997
A hypothetical martensitic steel has been compositionally designed in order to optimize both metallurgical and reduced activation properties. When compared with two other martensitic steels, its activation characteristics are shown to be superior for all activation indices examined. However, these excellent properties are found to be due to the assumed

Butterfly martensite in industrial steels

Metallography, 1987
Abstract The morphology and the conditions of formation of butterfly martensite observed in carbon tool steels, low-alloy tool steels and bearing steels have been investigated. The results indicated that the butterfly martensite in various steels in three dimensional space can be classified into two types: i.e., the butterfly martensite with tails ...

Nanostructured martensite–austenite dual phase steels

Materials Science and Technology, 2012
Nanostructured martensite–austenite microstructure was achieved by a quenching–partitioning–tempering (Q–P–T) treatment of high carbon low temperature bainitic steel. Microstructure observations showed that the nanostructured steel consisted of fine martensite (about 25 nm in thickness), retained austenite and carbides.

Martensitic Steels

Abstract Martensitic (MS) steel is produced by quenching carbon steel from the austenitic phase into martensite. This chapter presents the compositions, microstructures, processing, deformation mechanism, mechanical properties, hot forming process, and attributes of MS steels.

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 ...

Welding Metallurgy of Low Carbon Chromium-Nickel Martensitic Stainless Steels (Soft Martensitic Steels)

1988
According to Gysel, Gerber and Trautwein [369] the relatively poor weldability of chromium stainless steels, their cold cracking sensitivity and the often unsatisfactory mechanical properties obtained from welded joints led at the end of the fifties to the development of low carbon martensitic chromium-nickel steels.

Nitride-Strengthened Ferritic/Martensitic Steel

2013
Nitride-strengthened reduced activation ferritic/martensitic (RAFM) steel is anticipated to have higher creep strength because of the remarkable thermal stability of nitrides. Such steels with different manganese contents are designed based on the chemical composition of Eurofer 97 steel but the carbon content is reduced to an extremely low level.

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.

The martensite transformation in stainless steel

Acta Metallurgica, 1963
Abstract 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.
