Abstract

TiNb/Zr₅₅Cu₃₀Al₁₀Ni₅ and TiNb/Cu₄₆Zr₄₂Al₇Y₅ bulk metallic glass composites were prepared by Spark Plasma Sintering (SPS). The compression results show that TiNb/Zr₅₅Cu₃₀Al₁₀Ni₅ composites get larger plasticity than TiNb/Cu₄₆Zr₄₂Al₇Y₅ composites. The reason is that Zr₅₅Cu₃₀Al₁₀Ni₅ bulk metallic glass is resistant to micro-crack. The fracture toughness test proves that K_C of Zr₅₅Cu₃₀Al₁₀Ni₅ is higher than that of Cu₄₆Zr₄₂Al₇Y₅, so there is a larger length scale of plastic process zone R_p for Zr₅₅Cu₃₀Al₁₀Ni₅.
