| Abstract | Self-propagating high-temperature synthesis (SHS) of porous NiTi alloy for hard tissue implants shows shape memory effect and superelasticity due to the B2 <-> B19' transformation. In order to decrease the A(f) temperature to the human body temperature, 310 K, the effects of preheating temperature, thermal cycling and the third element Mo on the transformation temperatures were investigated using differential scanning calorimetry. The experimental results indicate that the preheating temperature has no obvious effect on the transformation temperatures; the transformation temperatures slightly decreased with increasing number of thermal cycles, but the At temperature was still above 310 K within 10 times; the addition of Mo decreased transformation temperatures considerably, and the R-phase transformation was induced during cooling. Transformation temperatures of porous TiNi(Mo) shape memory alloys with appropriate Mo contents fabricated by SHS meet the demands for human-body implants. (c) 2006 Elsevier B.V.
