Abstract: Compared with the smelting and casting method, powder metallurgy method can avoid impurities and improve the utilization rate of materials. The microstructures and properties of pure titanium prepared by microwave sintering and conventional sintering were studied in this paper. The results show that, the equiaxed grain α-Ti microstructure is acquired by conventional sintering at 1200 ℃ for 2 h, the relative density, density, hardness, compressive strength, and fracture expansion rate are 96.06%, 4.33 g·cm^-3, HV 260, 1309 MPa, and 10.63%, respectively. The conventional sintering titanium samples display the typical cleavage brittle fracture. Furthermore, the equiaxed grain α-Ti and strip β-Ti microstructure are acquired by microwave sintering at 1200 ℃ for 15 min, the relative density, density, hardness, compressive strength, and fracture expansion rate are 95.45%, 4.30 g·cm^-3, HV 311, 1175 MPa, and 18.89%, respectively. The microwave sintering titanium samples display the quasi-cleavage brittle fracture.
