Shape Memory Effect and Superelasticity of [001]-Oriented (TiZrHf) 50 Ni 25 Co 10 Cu 15 High-Entropy Alloy Crystals Under Compression

For the first time, the shape memory effect (SME) and superelasticity (SE) of [001]-oriented single crystals of a (TiZrHf) 50 Ni 25 Co 10 Cu 15 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 Ni 25 Co 10 Cu 15 HEA single crystals are high-strength materials with the high-temperature SME and SE.
