Materials letters Vol. 291. P. 129430 (1-3)Abstract: The present paper focuses on the analysis of functional fatigue properties in <001>-oriented single crystalline Fe-Ni-Co-Al-Ta shape memory alloys. Superelastic cycling experiments up to 4.5% at different temperatures were conducted and revealed excellent cyclic stability at lower testing temperatures. Transmission electron microscopy observations shed light on the influence of precipitation and dislocation activity on functional stability.
