Abstract
Dual amorphous phase bulk metallic glasses (DAPBMGs) contain two distinct amorphous alloys in order to combine the favorable properties of each phase. A viable method for obtaining dual bulk amorphous alloys is powder metallurgy. In this study, a Zr/Fe DAPBMG was successfully prepared by hot-pressing Zr-based and Fe-based glassy alloy powders in various volumetric proportions. The samples obtained were structurally analyzed by scanning electron microscopy and x-ray diffraction, and their magnetic properties were determined using an integrator fluxmeter-type hysteresis graph. It was found that increasing the volumetric ratio of the Fe-based alloy decreases coercivity and increases saturation magnetization.
