摘要
For the first time, the shape memory effect (SME) and superelasticity (SE) of [001]-oriented single crystals of a (TiZrHf)(50)Ni25Co10Cu15 high-entropy alloy (HEA) are studied under compression. SE is observed within a wide temperature range from M-s = 404 K to 530 K. The maximum SE is 4.4%, and the SME is 3%. The (TiZrHf)(50)Ni25Co10Cu15 HEA single crystals are high-strength materials with the high-temperature SME and SE.
