Ti particles dispersed Ti-based metallic glass matrix composite prepared by spark plasma sintering

Abstract

Using spark plasma sintering (SPS) process, Ti particles dispersed Ti 40Zr10Cu36Pd14 metallic glass (MG) matrix composites were fabricated. The X-ray diffractometry (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and compressive tests were used for examining the microstructure and properties of the composites. The experiment results showed that the as-sintered composite exhibited mainly dense structure. The Ti-based MG and pure Ti particles were coalesced together closely. There was no distinct gap or interface between the Ti-based MG matrix and pure Ti particles. No crystallization was observed in the Ti-based glassy matrix. The addition of Ti particles improved the plasticity of the Ti-based MG composite, while had no significant influence on the thermal stability of MG matrix. © 2013 The Japan Institute of Metals and Materials.
