Abstract
Porous Ni-Ti shape memory alloys (SMAs) have been successfully produced by self-propagating high-temperature synthesis (SHS) and conventional powder s intering. The alloys produced by these two methods have very different char acterization of pore structure, fracture mechanism and DSC profiles. Moreov er, it is easy to produce bulk samples of porous Ni-Ti SMAs by SHS and the pre-heating temperature is very important for successful preparation of por ous Ni-Ti SMAs. Pre-heating temperatures between 150 degrees C and 550 degr ees C are suitable in the present study.
