Their unique design concept and vast compositional diversity offer unprecedented opportunities for the development of advanced hydrogen\u0000storage materials. This review aims to systematically analyze the current research status of high-entropy alloys for hydrogen storage, with a focus on compositional designs, synthesis processes, and hydrogen storage characteristics. The review also examines correlations between hydrogen storage performance and composition-related properties, particularly for hydrogen storage alloys crystallizing as BCC solid solutions and Laves phase structures. Various aspects of hydrogen interaction with HEAs, including reversibility of hydrogen storage, cycling stability, and activation behavior have been considered in detail. The potential of HEAs in the development of novel hydrogen\u0000storage materials with superior performance is highlighted, emphasizing the importance of effective compositional design and synthesis methods.","PeriodicalId":54580,"journal":{"name":"Problems of Atomic Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This results from thermo-elastic internal stresses arising during irradiation of the\u0000alloy with a pulsed electron beam. The value of residual internal stresses in the irradiation-remelted layer is 43 MPa. Since it is impossible to determine the deformation mechanisms during cooling of the remelted layer by direct methods, conclusions about the deformation mechanisms were made by studying the relief of the irradiated surface. This study shows that deformation processes during irradiation of AA1933 aluminum alloy can develop in different parts of the irradiated surface by different mechanisms. Deformation can be carried out by both dislocation slip and grain-boundary slipping mechanisms.","PeriodicalId":54580,"journal":{"name":"Problems of Atomic Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140713658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the maximum values of the yield strength and the ultimate tensile strength are observed at the aluminum content of 3.5 wt.%.

Samples of all materials were irradiated under identical conditions with 1.4 MeV Ar ions at room temperature. Transmission electron microscopy (TEM) was used to characterize the radiation defects and microstructural changes. Nanoindentation was employed to measure the effect of ion irradiation on hardening. The dependence of the hardening parameters on the irradiation dose, their relationship with the evolution of the microstructure was studied. It was found, that the developed alloys exhibited a reduced susceptibility to irradiation induced hardening compared to that of conventional SS316 and 18Cr10NiTi stainless steels.
