In this paper, TiC/NiTi composite powders were prepared by putting Ni, Ti and C powders into a molten salt bath. The as-prepared composite powders were then sintered by a cubic high-pressure apparatus to produce bulk composite materials at a very short time. It was found that the composite was composed of TiC particles embedded in NiTi matrix, in which a small amount of Ti2Ni was also detected. The martensitic transformation of the NiTi matrix was evidenced by differential scanning calorimetry analysis.
