Spark plasma sintering (SPS), as a developed rapid sintering technique, has a great potential for producing larger metallic glassy alloy specimens in a variety of shapes than those fabricated by casting methods, and can readily produce composites by dispersing crystalline particles in the glassy matrix. In this study, the Ni52.5Nb10Zr15Ti15Pt7.5 bulk metallic glassy matrix composites dispersed homogeneously with ceramics ZrO2 particulates were fabricated by the SPS process. The plastic ductility of the Ni52.5Nb10Zr15Ti15Pt7.5 glassy matrix composites was improved by adding ZrO2 particulates into the glassy alloy. The matrix of the fabricated composites maintained a glassy phase after the SPS process.
