Ferritic and Tempered Martensitic Steels
, 2019 This chapter begins with a short overview of the historical development of the ferritic/martensitic steels for nuclear energy systems, followed by a section that outlines the numerous nuclear applications where this type of steels are currently used or foreseen in future applications.

On the Theory of '225' Martensite in Steels
physica status solidi (b), 1965AbstractThe 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.

The nucleation of martensite in steel
Acta Metallurgica, 1976Abstract 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.

On the growth of martensite in steel
Acta Metallurgica, 1980Abstract 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.

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.

The martensitic transformation in stainless steels of the austenitic-martensitic class
Metal Science and Heat Treatment of Metals, 19601. 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.

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.

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 ...
