In this work, a series of CoCrNi MEAs is prepared by adjusting the laser power (175–250 W) of selective laser melting (SLM). All SLM-fabricated samples exhibit greater oxidation resistance than that of the rolled alloy, attributed to their higher grain boundary densities. The oxide scales formed on SLM-fabricated samples comprise a continuous Cr₂O₃ layer, whereas those on the rolled sample feature an inner Cr₂O₃ layer with an outer (Co, Ni)Cr₂O₄ spinel structure. Among the samples, sample III, produced at a laser power of 225 W, exhibits an increased proportion of high-angle grain boundary (HAGB), which can facilitate Cr outward diffusion, and a reduced proportion of low-angle grain boundary (LAGB) and &lt;100&gt; preferred orientation, which can hinder oxygen inward diffusion. These unique characteristics of sample III facilitate the formation of a protective oxide films, thereby reducing mass gain and resulting in enhanced high-temperature corrosion resistance.</div></div>","PeriodicalId":331,"journal":{"name":"Intermetallics","volume":"182 ","pages":"Article 108764"},"PeriodicalIF":4.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In comparison with the cast alloy, the strength for the designed microfiber is increased by 2.75 times and there appears the 70 % enhancement for the electrical conductivity. The strengthening mechanisms can be attributed to the phase transition from FCC to B2 phase, grain refinement, and the formation of Ru and Ag precipitates. Furthermore, the significant improvement in electrical conductivity is primarily due to the introduction of the B2 ordered phase and the elongation of longitudinal grains.

Extensive molecular dynamics simulations have demonstrated that potential energy gradient MGs, characterized by a spatial gradient distribution of free volume, possess a \"shear band deflection\" ability. This free-volume gradient structure promotes the branching and deflection of shear bands, disperses deformation, and delays damage, thereby conferring additional plasticity to the gradient MGs. Concurrently, the high icosahedral content in potential energy gradient MGs contributes to their strength.
