Ti-Ni shape memory alloy (SMA) was fabricated by a spark-plasma sintering method using two types of powders prepared in different processes : the Ti&Ni powder mixture mechanical-alloyed into an amorphous state by processing for 360ks (MA method), and the Ti&Ni powder mixture V-blended for 3.6ks (V-blender method). The fabricated alloy by the MA method showed more uniform phase of TiNi than that by the V-blender method produced in a same manner, however the former showed a lower density than the later due to a larger particle size of its mixture powder of before-sintering.
