Abstract

Bulk metallic glass (BMG) Fe₇₅Hf₃Mo₃B₁₅Y₄ can be cast into glassy rod with a diameter of at least 2 mm by copper mold casting technique under a low vacuum of 1.5 Pa. The alloy exhibits a large supercooled liquid region of 57 K and high glass transition temperature of 855 K, demonstrating a good thermal stability. Moreover, the as-cast BMG also shows good soft magnetic properties with a high saturation magnetization of 95 emu/g and low coercivity of around 1.4 Oe at room temperature.
