Laser heat treatment of martensitic steel and dual-phase steel with high martensite content
Materials Science and Engineering: A, 2019 Laser heat treatment of galvanised steels with a martensite content superior to 80% were performed on a 1 cm wide area over an extensive temperature range [620 K - 1350 K]. The material softening induced is studied through uniaxial tensile testing and SEM microstructural observation. A treatment temperature close to Ac3 yields a massive increase in the

On the Mechanism of the Martensite Formation in Steel
Journal of the Japan Institute of Metals and Materials, 1948 The ‘Umklappen’ which is the process of the formation of one martensite (α') needle, takes place in an extremely short time. This process, therefore, must be adiabatic and needs no diffusion of atoms, that is, no change of composition, consequently, when the austenite (γ) is cooled from point X (Fig. 2 and 3).
