The problem of ductile-brittle transition of amorphous alloys
No full textThe phenomenon of ductile-brittle transition of melt-quenched iron-based amorphous alloys that occurs at room temperature after appropriate heat treatment is considered. A structural model founded on the relaxation growth of microdiscontinuities which initiate microcracks under external stresses is suggested
Martensitic Transformation in Microcrystalline Melt-Quenched Fe-Ni Alloys
No full textThe 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
