Uniaxial tensile deformation properties of the TiNi shape memory alloy were investigated for the subloop loading under the stress-controlled condition. The results obtained are summarized as follows. (1) The stress-induced martensitic transformation on the surface of the material can be observed by using the microscope and the thermography. (2) In the subloop loading of the stress-controlled condition, the martensitic transformation progresses and strain increases in the initial stage of the unloading process since the temperature of the material decreases during unloading.
