Enhancement of mechanical properties of a soft magnetic Fe-based metallic glass

In this study, the effect of non-isothermal partial crystallisation on microstructure, and mechanical and magnetic properties of (Fe 0.9 Ni 0.1 ) 77 Mo 5 P 9 C 7.5 B 1.5 BMG was investigated. Microstructural characterisations revealed that there was a phase separation in the as-cast BMG. Formation of nano-crystalline phases first occurred in the separated amorphous phase during initial stages of crystallisation process and then continued in the matrix phase. The nanocrystalline/amorphous matrix composite exhibited higher mechanical and magnetic properties compared to those of the as-cast BMG.
