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 M s point is shown to decrease but volume percentage of athermal martensite is found to be invariable with austenite grain size change.
