Aimed to two kinds of TiNi alloy, that is, initial shape-memory effect TiNi alloy and pseudo-elastic TiNi alloy, the transient temperatures at the surfaces of the TiNi alloy specimens were measured during dynamic deformation in real time by using the compression split Hopkinson pressure bar device with an infrared detector system.And the corresponding temperature changes were calculated according to the experimental stress-strain curves.Temperature-measurement results indicate that significant temperature change was observed in the process of phase transformation.Specifically, during loading, the temperature increased with the increasing of the phase transformation strain, and reached its highest at the highest phase transformation strains.While during unloading, for the initial pseudo-elastic specimens, the temperature decreased significantly, in contrast, for the initial shape-memory effect specimens, the temperature kept the highest temperature constant or dropped, which is depended on the highest loading temperature.After a cycle of loading/unloading, the temperatures of the specimens with two initial states are higher than their initial ones.The calculated results show that the effect of transformation dissipation work on the temperature change can not be ignored.
