Progress of Cryogenic Deformation and StrengtheningToughening Mechanisms of High-Entropy Alloys

Abstract

Owing to the multi-principal element and higher intrinsic configurational entropy, high-entropy alloys exhibit excellent mechanical and physicochemical performance, which has garnered extensive attention from researchers. By virtue of the excellent performances in terms of superior strength, ductility, toughness, impact resistance property, and adjustable phase stability, especially in cryogenic environments, high-entropy alloys have broad application prospects in fields such as deep-space exploration, low temperature superconducting, and the gas industry. In this paper, the deformation and strengthening-toughening mechanisms of high-entropy alloys are summarized by reviewing the cryogenic progress. Furthermore, the promising research directions of high-entropy alloys in cryogenic engineering application combined with the performance of traditional cryogenic materials are also presented.
