- Abstract
- The evolution of sinterability, microstructure and mechanical properties for the spark plasma sintered(SPS) Ti from commercial pure titanium(CP-Ti) was studied. The densification of titanium with 200 mesh and 400 mesh pass powder was achieved by SPS at 750~1100oC under 10 MPa pressure and the flowing H2+Ar mixed gas atmosphere. The microstructure of Ti sintered up to 800oC consisted of equiaxed grains. In contrast, the growth of large elongated grains was shown in sintered bodies at 900oC with the 400 mesh pass powder and the lamella grains microstructure had been developed by increasing sintering temperature. The Vickers hardness of 240~270 HV and biaxial strength of 320~340 MPa were found for the specimen prepared at 950oC.
