On the Theory of '225' Martensite in Steels

physica status solidi (b), 1965
AbstractThe physical basis of a general theory of martensite is delineated which accounts for the observation of composite martensite consisting of twinned and untwinned regions and which is consistent with the observation that no twinning system other than (112)M has ever been reported for any steel martensite.

On the growth of martensite in steel

Acta Metallurgica, 1980
Abstract Criteria based on minimum energy and maximum stress considerations have been developed for the first stages of growth of martensite in steel. It is shown that the critical size of nucleus at which dislocation-assisted growth can occur is about 25 nm diameter.

The nucleation of martensite in steel

Acta Metallurgica, 1976
Abstract Calculations of the total energy for transforming austenite to martensite in the form of thin ellipsoidal plates, fully coherent with the austenite, show that the process may be spontaneous in the presence of pre-existing dislocations.

Martensitic Steels

2013
Abstract Martensitic steels are produced by quenching carbon steel from the austenite phase into martensite. This chapter provides information on the composition, microstructures, processing, deformation mechanisms, mechanical properties, hot forming, tempering, and special attributes of martensitic steels.

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 martensitic transformation in stainless steels of the austenitic-martensitic class

Metal Science and Heat Treatment of Metals, 1960
1. Heating to 525–950°C after austenitizing at 1050°C reduces substantially the stability of austenite. Destabilization of austenite is explained by a depletion of the solid solution in chromium and carbon by chromium carbide precipitation. 2.

Martensitic Sheet Steels

2015
Sheet martensitic steels for automotive application are presented including as-annealed martensitic grades, as-hot-rolled grades, and grades where martensitic structure is obtained after quenching in cooled dies (press-hardened martensitic steels). New developments of ultrahigh strength as-annealed and press-hardened steels with tensile strength up to ...
