Progress of Cryogenic Deformation and Strengthening-Toughening Mechanisms of High-Entropy Alloys
Owing to the multi-principal element and higher intrinsic configurational entropy,high-entropy alloys exhibit excellent mechanical and physicochemical performance,which has garnered exten-sive attention from researchers.By virtue of the excellent performances in terms of superior strength,duc-tility,toughness,impact resistance property,and adjustable phase stability,especially in cryogenic envi-ronments,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.Fur-thermore,the promising research directions of high-entropy alloys in cryogenic engineering application combined with the performance of traditional cryogenic materials are also presented.
