Martensitic Transformation in Microcrystalline Melt-Quenched Fe-Ni Alloys

The features of martensite transformation in Fe - (31 - 32)% Ni melt-quenched alloys are considered. The melt-quenching was realized by spinning technique with variable parameters. The influence of the melt-quenching on structural and kinetics transformation parameters is revealed. In particular Ms point is shown to decrease but volume percentage of athermal martensite is found to be invariable with austenite grain size change
