主　　题：TiNi shape memory alloy porosint self-propagating high-temperature synthesis 

摘      要：TiNi shape memory alloy porosint, a promising artificial bone material, was prepared by self propagating high temperature synthesis method. It is found that the key technical parameter affecting the porosity, the shape and distribution of the bores in the synthesized product is the pre heating temperature of green compact. While the pre heating temperature varies between 523 K and 673 K, the TiNi shape memory alloy porosint with wholly homogeneously distributing bores will be gained. The porosity of the porosint is 70% when the pre heating temperature is near 673 K, which is maximal under different pre heating temperatures. The compressive strength of TiNi SMA porosint with a porosity of 70% manufactured by SHS is up to 100 MPa and the percentage recovered is 92%.
