Ti-Nb-Cu shape memory alloys were fabricated by powder metallurgy (PM) process. The fabrication conditions of the alloys and their shape memory properties were investigated. The relative density of the as-sintered alloy was more than 96% at a sintering temperature of more than 1123 K. It was found that the solution treatment is needed to homogenize the microstructure of the as-sintered alloy. Ti-18at%Nb-3at%Cu alloy clearly showed a two-step deformation and a superelastic behavior.
