• The effect of mechanical alloying condition on the characteristics of mechanically alloyed powder (MA powder) was investigated. The difference in sintering behavior between the MA powder and the elementally mixed powders by a V-blender (V-blended powder) and the microstructure and shape memory characteristics of the sintered alloys were also examined. The MA powder was fabricated by milling using a planetary ball mill and was sintered by a spark-plasma sintering method at various temperatures. The powder agglomerated and cold welded and its particle size became larger with an increase in milling time. The mixture of Ti and Ni powders changed into an amorphous state by processing for 3.6ks more than 300rpm. The alloy of the MA powder showed more homogeneous phase of TiNi than that of the V-blended powder produced in a same manner, however the former showed a lower density than the later due to a larger particle size of its MA powder of before-sintering.
