The black grains are the martensitic phase and the white the non-transformed austenite. The transformation does not involve diffusion processes but lattice displacement of atoms by shear produced by ...

the team developed nano-porous martensitic alloys using reactive gases like ammonia, which simultaneously remove oxygen and introduce nitrogen into the material's structure. This sustainable ...

They have less elastic strain than martensite and the carbide phase is more dispersed giving a more ductile material. Pearlite and bainite can also have their cementite morphology changed to this ...
