| Research Abstract |
TiC particle dispersed Ti matrix composites were successfully synthesized by reactive arc-melting method from Ti, C and N (TiN powder or gaseous nitrogen) system. Plate-like α-Ti was precipitated in the resulting TiC particles. Therefore Vickers hardness was obviously decreased compared to that of a monolithic TiC. It seems to be considered that precipitated α-Ti enhances the ductility of the TiC particles and nitrogen solution strengthens the matrix Ti. Those results clearly show that new conceptual bi-modal Ti matrix composites can be synthesized by reactive arc-melting methods.
