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 Individual

A two-phase constitutive model for shape memory alloys (SMAs) is proposed based on the fact that SMAs is dynamically composed of austenite and martensite. The behavior of SMAs is regarded as the dynamic combination of the individual behavior of each phase. This model can describe the main characteristics of SMAs, such as pseudoelasticity and shape memory effect. The corresponding numerical algorithm was also developed to describe the main features of shape memory alloy Au-47.5at.%Cd.
