The concept of the habit plane and the phenomenological theories of the martensite transformation [PDF]

, 1972
Three different interpretations of a martensite habit plane are in use: \ud \ud 1. (a) the plane of the plate of a plate-shaped crystal,\ud \ud 2. (b) a semi-coherent plane glissile interface,\ud \ud 3.

Crystallographical Analysis on Martensite Transformation and Martensitic Morphology.

ISIJ International, 1997
The strain tensor and displacement vector associated with lattice deformation were introduced to discuss the effect of self-accommodation and plastic accommodation in martensitic transformation and the crystallographic models for {557} f , {225} f and {31015} f martensite were proposed, along with their experimental verification.

Influence of pre-existing martensite on the wear resistance of metastable austenitic stainless steels [PDF]

, 2016
The effect of pre-existing martensite on the sliding wear behavior of a commercial metastable austenitic stainless steel was investigated. Two different steel conditions were considered: annealed (with a fully austenitic microstructure) and cold rolled ...

Magnetocaloric Effect Caused by Paramagnetic Austenite–Ferromagnetic Martensite Phase Transformation [PDF]

, 2018
In the present work, the magnetization of Ni50Mn17.5Ga25Cu7.5 alloy undergoing the first-order phase transition from paramagnetic austenite to ferromagnetic martensite was measured to evaluate the magnetic-field-induced entropy change (MFIEC) and ...
