Temperature memory effect in the solution-treated Ti-Ni-Hf-Y high temperature shape memory alloy (HTSMA) was investigated. The results showed that the temperature memory effect induced by the partial cycling could be detected in the subsequent complete transformation cycling for the solution-treated Ti-Ni-Hf-Y alloy. The temperature memory effect is one-time phenomenon. However, the temperature memory effect could last at least 20 times when the sample was employed 10 times complete thermal cycles. Multiple-steps temperaure memory effect can be observed as the sample undergoes the lower temperature partial thermal cycle in sequence. The mechanisms of the temperature memory effect were discussed in this paper.

The temperature memory effect of shape memory alloy (SMA) induced by an incomplete martensitic inverse phase transformation has the potential values in various engineering fields. It is of theoretical and practical interests to establish a phase transformation model which overcomes the limitation that previous phase transformation models of SMA fail to take into account the temperature memory effect. In this paper, the curves of heat flow versus temperature of SMA during the martensitic phase transformation and martensitic inverse phase transformation are described as the quadratic functions of temperature. A new phase transformation model of SMA is developed based on the differential relationship between martensitic volume fraction and phase transformation free energy. Numerical results show that the new model well predicts the phase transformation behaviors of SMA associated with the temperature memory effect.
