Abstract

Micro-laminated TiC/Ti composite was fabricated by an in-situ method that evolves hot-pressing sintering Ti and graphite foils. The microstructure and mechanical properties of micro-laminated TiC/Ti composite were investigated in present work. It was observed that the TiC ceramic layers and the Ti layers were alternately distributed after sintering. The micro-laminated TiC/Ti composite exhibited flexural strength of 690 ± 30 MPa and fracture toughness of 24.78 ± 0.71 MPa*m^1/2 which are much higher than those of traditional TiC ceramics and cermets. The improved fracture toughness attributes to ductile Ti layers, multiple-layers structure and strong interfaces bonding between Ti and in-situ formed TiC layers. In addition, the method used in this study was much simpler and more cost-effective than traditional powder sintering method for fabricating micro-laminated composite, therefore, is promising for real application.
