Martensitic transformations in alloys with martensite which ages
Metal Science and Heat Treatment, 19641. Molybdenum decreases the temperature interval in which martensite is formed in Fe+20% Ni alloys, while cobalt increases it. The additional elements investigated here affect the temperature interval of the martensitic transformation in the same way as that in steel. 2.

Martensitic Transformations in Bochum
Angewandte Chemie, 1989Conference Reports: Martensitic transformations are first order structural phase transformations which occur in a range of crystalline solids. A recent meeting in this field in Bochum, FRG, is reviewed by N. Jost while W. Kaysser reports that Las Vegas was the scene of a conference on particle technology.

The formation of martensite is characterized by its athermal transformation kinetics, crystallographic features, and development of fine structure. This chapter describes the diffusionless, shear-type transformation of austenite to martensite and how it affects the morphology and microstructure of heat-treatable carbon steels.

Surface Upheavals, Pseudo Martensite, and Martensite Ghosts
Practical Metallography, 2005Abstract A survey is made on the application of some metallographic methods for the analysis of martensitic reactions. In this context the following aspects are discussed: Reverse reactions can be martensitic, to restore faultlessly the austenite, not fully reversible (defects accumulate), or diffusion controlled. In

Metallurgical Transactions A, 1976
Results concerning the crystal lattice of freshly formed martensite with abnormally low and abnormally high axial ratioc/a as well as the results of neutron diffraction studies of the positions of carbon atoms are reviewed. Mechanisms of the austenite to martensite transformation are considered, which can explain the formation of martensite with ...

An explanation of the “martensite start”-“martensite finish” temperature interval
Solid State Communications, 1982Abstract Packing together the domains of transformed and untransformed material after the start of a martensitic transformation produces stress, the equilibrium proportions of the two phases being governed by a stress-strain equation. This equation, however, relates the volume of transformed material to the fundamental order parameters of the ...

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.
