Abstract
The superelastic response of the Fe43.5Ni28Co17Al11.5Ti2.5 single crystalline shape memory alloy was investigated along the [1 0 0] orientation in both tension and compression. A fully recoverable superelastic loop was observed under both tension and compression within the temperature range of -80 to 0 °C. At higher temperatures, while up to 6% superelastic strain was attainable in tension, the superelasticity deteriorates quickly under compressive strains exceeding 2%. The asymmetric response is likely caused by different numbers of stress-activated martensite variants in tension and compression.
