Fabrication of novel TiZr alloy foams for biomedical applications
چکیده انگلیسی

Bone injuries and failures often require the inception of implant biomaterial. Research in this area has received increasing attention recently. In particular, porous metals are attractive due to its unique physical, mechanical, and new bone tissue ingrowth properties. In the present study, TiZr alloy powders were prepared using mechanical alloying. Novel TiZr alloy foams with relative densities of approximately 0.3 were fabricated by a powder metallurgical process. The TiZr alloy foams displayed an interconnected porous structure resembling bone and the pore size ranged from 200 to 500 μm. The compressive plateau stress and the Young’s modulus of the TiZr foam were 78.4 MPa and 15.3 GPa, respectively. Both the porous structure and the mechanical properties of the TiZr foam were very close to those of natural bone.
