摘要：
Biomedical porous NiTi alloys, being composed of mainly NiTi phase with a little Ti2Ni phase and no Ni3Ti phase, were fabricated by a microwave sintering technique. They presented an isotropic and three-dimensionally interconnected pore microstructure with the pore size of 20-100 mu m. The compressive strength and elastic modulus of the porous NiTi alloy were about 360 MPa and 5.5 GPa, respectively. At the same time, the porous NiTi alloys possessed excellent corrosion resistance in Hank's solution. Therefore, the porous NiTi alloys fabricated by the microwave sintering technique would be good candidates for ideal biomaterials, used potentially as the heavy load-bearing hard tissue implants.
