抄録

The glass-forming ability of the Hf₅₀Cu₃₀Ni₁₀Al₁₀ alloy was examined by melt-spinning and copper mold casting methods. A new Hf₅₀Cu₃₀Ni₁₀Al₁₀ bulk glassy rod of 3 mm in diameter was formed by copper mold casting. The crystallization temperature (T_x), glass transition temperature (T_g) and T_g⁄T_l of the glassy alloy rod were 780 K, 860 K and 0.61, respectively. The Hf₅₀Cu₃₀Ni₁₀Al₁₀ bulk glassy alloy exhibits density of 11.0×10³ kg/m³, Vickers hardness of 590, Young’s modulus of 118 GPa and compressive fracture strength of 2420 MPa. The synthesis of the Hf-based bulk glassy alloy with high T_g⁄T_l, high fracture strength and high density is encouraging for future application of bulk glassy alloys.
