Series: ASM Handbook
Volume: 9
Publisher: ASM International
Published: 01 December 2004

...Abstract Abstract Martensite is a metastable structure that forms during athermal (nonisothermal) conditions. This article reviews the crystallographic theory, morphologies, orientation relationships, habit plane, and transformation temperature of ferrous martensite microstructures. It examines...

Fig. 11 Hardness values for 50% martensite and 100% martensite conditions in quenched carbon steels as a function of carbon. With 50% martensite, the hardness depends on the structure of the other 50% and residual or alloying. Steel with more alloying would be at the top of the band. Source: Ref More

...Abstract Abstract This article assesses the evolution of martensite modeling in the changing materials engineering environment. It describes the physics of displacive transformations using Ginzburg-Landau theory, microstructure representation, dynamics and simulations, density functional theory...
