Mechanical alloying process has been used to prepare shape memory alloy with nanocrystalline structure and nominal compositions of Ni40Ti50Cu10 (at٪) from the elemental powders. The product was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) .The results exhibited that after 60 h milling, the Cu dissolve into NiTi structure and the low crystalline NiTi(110) phase was obtained. Annealing of the milled powders at 1173 K for 30 min, leads to grain growth, decrease of microstrain finally formation of nanocrystalline NiTiCu alloy.
