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 KC of Zr55Cu30Al10Ni5 is higher than that of Cu46Zr42Al7Y5, so there is a larger length scale of plastic process zone Rp for Zr55Cu30Al10Ni5.
