Thermomechanical investigations of TiNi Shape Memory Alloy subjected to tension test were performed. Taking advantages from a thermovision camera, a temperature distribution on the specimen surface and the average temperature variation were found. Nucleation and development of the new martensitic and parent phases in the shape memory alloy subjected to stress-induced phase transformations were studied. It was observed during tension test that narrow inclined bands, similar to Lüders phenomena, of considerably higher temperature related to martensite phase appeared starting from the central part of the specimen and developing in two almost perpendicular directions towards grips. The non-uniform temperature distribution, related to the heterogeneous phase transformation, was observed also during unloading, while similar bands of the reverse transformation occur, accompanied by a significant temperature decrease. The bands of both martensite and parent phase fronts were characterized by the temperature variations of about 8 K and the slope of inclination of about 48 degrees.
