This paper addresses the issue of the mechanical properties of NiTi shape memory alloy (NiTi SMA) as a driving material being unclear. It begins from the standpoint of active temperature control and uses differential scanning calorimetry (DSC) and uniaxial tensile testing to evaluate the performance of NiTi SMA under various working conditions. The stress-strain characteristics and thermal reversible properties of NiTi shape memory alloys (SMA) at various loading rates, distinct SMA configurations, and varying strain amplitudes were examined through experimental methods.From the analysis of the test results, it can be seen that NiTi SMA exhibits similar mechanical properties under different working conditions, while NiTi SMA will produce recovery stress when it is heated, and it is positively correlated with temperature.
