摘要：

Porous Ni-Ti shape memory alloys (SMAs) are promising candidates for biomedical materials. In the present study, a bulk porous Ni-Ti SMA with a banded structure of channels and 54 vol.% porosity has been successfully prepared by self-propagating high-temperature synthesis (SHS). The Ni-Ti SMA synthesized has an open porous structure, also its pores and channels with various size and shape are three-dimensionally interconnected. Compared to the conventional pou der sintering method, the present method extends the porosity range of porous Ni-Ti SMAs. A schematic representation of SHS synthesized Ni-Ti SMAs has been suggested.
