摘要：

Metallic glass (MG)/metallic glass composites being CuA (Cu-base alloy)/10% NiA (Ni-base alloy) and NiA/10% CuA in weight were newly synthesized using gas atomization and spark plasma sintering (SPS). The composition of MG powders was Cu54Ni6Zr22Ti18 (CuA) and Ni59Zr15Ti13Nb7Si3Sn2Al1 (NiA), which consisted of fully amorphous phases. T-g and T-x of both the powders were 716 K and 765 K for CuA, but 836 K and 890 K for NiA. The resultant phases of composites were Cu crystalline dispersed NiA matrix composites as well as NiA phase dispersed CuA matrix composites, depending on the SPS temperatures. The effect of the second phases embedded in the MG matrix on microstructure and mechanical properties is discussed. (c) 2006 Elsevier B.V. All rights reserved.
