Abstract

Oxygen embrittlement in Zr-based bulk amorphous alloys is an important problem, which must be solved before the application of the bulk amorphous alloys to industrial materials. In the Zr–Cu–Al ternary system, the cast bulk amorphous Zr₅₀Cu₄₀Al₁₀ alloy near the ternary eutectic composition shows good ductility, in the case of the restriction of crystalline inclusions. Furthermore, the addition of Ni element brings about much higher ductility because of the proof ability against oxygen embrittlement. As a result, the Zr₅₀Cu₃₀Ni₁₀Al₁₀ bulk amorphous alloy exhibits good ductility and proof ability against oxidization.
