Impact of test temperature on functional degradation in Fe-Ni-Co-Al-Ta shape memory alloy single crystals

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 temp...

Description
Summary: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.
