摘要：
Superelasticity (SE) and shape memory effect (SME) of [0 1 1](B2)-oriented single crystals in B2-phase of the (TiZrHf)(50)Ni25Cu15Co10 high-entropy alloy (at.%), with B2-B19' martensitic transformation, have been studied in the post-growth state under compression. It is shown that SE is observed within a wide temperature range of T = M-s = 404 K to 528 K. The maximum SE value is 4.4 %, and the SME reaches 4.3-4.7 %.
