Shape-Controlled TiCx Particles Fabricated by Combustion Synthesis in the Cu-Ti-C System
TiCx particle-reinforced Cu-matrix composites were prepared in the Cu-Ti-C system by thermal explosion and hot press. Extracted TiCx particles with various shapes of in situ TiCx particles in the Cu-Ti-C system were observed through the Field Emission Scanning Electron Microscope (FESEM). It was fou...
