The heat treatment effect on transformation properties of a NiTi Shape Memory Alloy(SMA)film is discussed. TiNi SMA films were deposited by using sputter deposition techniques, and were then solution-treated and aging-treated. The phase transformation properties were investigated by means of a differential scanning calorimeter(DSC), X-ray diffractometer and a transmission electron microscope(TEM). As sputtered film had an amorphous structure with fluctuating density of titanium atoms. The films solution-treated at 600℃ and aging-treated at 400℃ had several kinds of phases. The rhombohedral phases, austenite phases and amorphous phases could be distinguished within the same film. The film solution-treated at 800℃ and aging-treated at 400℃ showed the largest enthalpy of the transformation and had the preferable crystalline structure. The samples solutioin-treated at 1000℃, in which NiTi were resolved partially into Ti_2Ni and Ni_4Ti_3 were more brittle.
