Abstract

The fabrication by combustion synthesis and properties of the porous NiTi SMA with appropriate pore characteristics and high strength were studied in this paper. The experimental results show the porous NiTi SMA with three-dimensionally interconnected pores has the isotropic pore structure. Besides two second phases (Ti₂Ni and Ti₃Ni₄) in small amount, the desired products, such as B2(NiTi) and B19'(NiTi) are the predominant phases in the porous NiTi SMA. The transformation temperatures of the porous NiTi SMA could be easily adjusted to the ideal values below or near the body temperature. Porous NiTi SMA has a high compressive strength (up to 500MPa), which can meet the strength demand of hard tissue implants and a low Young's modulus (5.82GPa) similar to that of natural bones. Such porous NiTi SMA is more suitable for the medical applications.
