Uniaxial compression can induce a large amount activation energy in a system, which builds up anisotropic elastic strain. This is especially common in a hexagonal close-packed (HCP) system. Utilizing the X-ray diffraction technique, we investigated the double-dome shaped evolution of its anomalous anisotropic strain when compressing a polycrystalline HCP\u2013silver\u2013aluminum (Ag75Al25) alloy up to 40 GPa. Analysis of the pressure-dependent grain size showed that the anisotropic strain relaxation was accompanied with grain-size refinement. This was a strong indication of microscopic structural anisotropy impacting both the mesoscopic mechanical properties and the macroscopic fracture behavior under uniaxial compression. Our findings provide valuable novel insights for further studies on materials with anisotropic mechanical properties.<\/jats:p>","DOI":"10.3390\/ma18071650","type":"journal-article","created":{"date-parts":[[2025,4,4]],"date-time":"2025-04-04T03:36:45Z","timestamp":1743737805000},"page":"1650","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Double Domes of Mesoscopic Localized Anisotropic Lattice Strain in HCP\u2013Ag75Al25 Under Uniaxial Compression"],"prefix":"10.3390","volume":"18","author":[{"given":"Zhexin","family":"Sun","sequence":"first","affiliation":[{"name":"Graduate School of China Academy of Engineering Physics, Beijing 100193, China"},{"name":"Center for High Pressure Science and Technology Advanced Research, Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1594-8008","authenticated-orcid":false,"given":"Mingtao","family":"Li","sequence":"additional","affiliation":[{"name":"Center for High Pressure Science and Technology Advanced Research, Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2510-5952","authenticated-orcid":false,"given":"Nana","family":"Li","sequence":"additional","affiliation":[{"name":"Center for High Pressure Science and Technology Advanced Research, Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8436-8731","authenticated-orcid":false,"given":"Wenge","family":"Yang","sequence":"additional","affiliation":[{"name":"Center for High Pressure Science and Technology Advanced Research, Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1121","DOI":"10.1007\/BF02900224","article-title":"The Relation between Polycrystal Deformation and Single-Crystal Deformation","volume":"1","author":"Kocks","year":"1970","journal-title":"Metall.
