Crystallization and mechanical properties of some Fe-Ni base metallic glass

Crystallization process has been determined as a function of time and temperature for the metallic glass Fe32Ni36Cr14P 12B6. The activation energy for the crystallization process was found to be 4.5 eV using an Arrhénius type equation. The stability of the studied alloy on annealing in the range 20 to 450 °C has been investigated by microhardness measurements. Also tensile tests were made as a function of time and temperature. The onset of crystallization of the same metallic glass has been determined numerically
