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

ABSTRACT

In this study, the effect of non-isothermal partial crystallisation on microstructure, and mechanical and magnetic properties of (Fe_0.9Ni_0.1)₇₇Mo₅P₉C_7.5B_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.
