Resum
The NiTi SMA was studied by temperature (mainly at 373 K) and by stress–temperature aging. The temperature induces monotonic changes in Rs transformation temperature near 10–20 K/year. The simultaneous stress/temperature aging produced strong changes in the stress–strain cycles and in the necessary stress to continue transforming with an increase of maximal stress near 45 MPa/month at 373 K.
