Abstract

Using a mixture of the gas-atomized Ni_52.5Nb₁₀Zr ₁₅Ti₁₅Pt_7.5 and Fe₇₃Si ₇B₁₇Nb₃ glassy alloy powders, we produced the two-phase bulk metallic glass (BMG) with high strength and good soft magnetic properties as well as satisfying large-size requirements by the spark plasma sintering (SPS) process. Two kinds of glassy particulates were homogeneously dispersed each other. With an increase in sintering temperature, density of the produced samples increased, and densified samples were obtained by the SPS process at above 773 K. Good bonding state among the Ni- and Fe-based glassy particulates was achieved.
