Abstract

We investigated the microstructure, in particular, the interface structure between powder particles in the Ni52.5Nb10Zr15Ti15Pt7.5 bulk glassy alloy composites containing 10 vol.%SiC particulates prepared by a spark plasma sintering (SPS) process by means of scanning and transmission electron microscopies. The SiC particulates were dispersed homogeneously in the Ni52.5Nb10Zr15Ti15Pt7.5 glassy matrix. No crystallization of the Ni52.5Nb10Zr15Ti15Pt7.5 glassy alloy took place during the SPS process. The good bonding states between SiC particulates and glassy matrix, as well as between glassy particles were recognized. No intermediate layer in the bonded interfaces was observed.
