Characteristic of principle properties and microstructure of TP-650 particles reinforced titanium matrix composites

The properties and microstructures have been researched for TiC particles reinforced titanium matrix composites(TP-650). Results indicate that the strength for this, composite at ambient. temperature were little varying with different heat treatment. The comprehensive properties of as-annealed composite with furnace cooling were superior to that with oil cooling and air cooling. The service temperature for TP-650 was about 50degreesCsimilar to100degreesC more than that of ordinary titanium alloys(i.e.IMI834,Ti-1100). It possessed better thermal stability over 500degreesC. The distribution of TiC particles was dispersive in titanium matrix. The microstructure was homogeneous and the interfaces between TiC particles and titanium matrix were metallurgical bond.
