Compressive property of porous NiTi alloy synthesized by combustion synthesis

Porous NiTi shape memory alloy (SMA) is a promising biomedical material applied as a human implant. Compressive properties of porous NiTi SMAs fabricated by combustion synthesis were investigated in this paper by compression tests. The results indicated that the nominal ultimate compressive strength and strain of porous NiTi SMAs were dependent on porosity and independent on strain rate. The compressive strength of porous NiTi SMA met the basic strength demand of human cancellous bone with corresponding porosity. (C) 2002 Elsevier Science B.V. All rights reserved.
