Martensitic phase transformations are rapid, diffusionless solid–solid transitions in which a parent crystal lattice reconfigures by coordinated shear and atomic shuffles into a martensite lattice.
The premartensite phase of shape memory and magnetic shape memory alloys is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry. The thermodynamic ...
DP steels contain islands of hard martensitic second phase in a ferritic matrix. Steel strength improves when the volume fraction of hard second phases increases. The formation of DP steels involves ...
