Mg-Y alloys have been actively studied because of their enhanced ductility and non-basal slip. Nonetheless, the mechanisms underlying mechanical behavior remain unresolved due to complex interactions among grains and grain boundaries in polycrystalline Mg alloys. In this study, an in situ tensile test was performed on a polycrystalline Mg-1 wt.%Y alloy in a scanning electron microscope (SEM) in conjunction with high-resolution electron backscatter diffraction (HR-EBSD). A total of 93 grains were systematically investigated through pre-analysis of Schmid factor, in situ analysis of geometrically necessary dislocations (GNDs), and post-deformation analysis of slip traces. The results show that <c+a> slip is activated both within grain interiors and near grain boundaries. The non-basal slip near grain boundaries was predominantly observed in grains with a low Schmid factor for pyramidal slip and exhibiting characteristic GND density evolution with increasing strain.

Red mud, a by-product of aluminum production via the Bayer process, represents a promising secondary source of REEs, particularly lanthanum (La). This study investigates the recovery of La from red mud using an integrated sulfating-roasting-water leaching (SRWL) process followed by adsorption. Mineralogical and chemical analyses confirmed that REEs were dispersed within the matrix rather than concentrated in a separate mineral phase. Water leaching studies of treated (sulfation-roasting) red mud at room temperature showed that leaching time was the dominant parameter, and up to 90% REE recovery could be achieved after 96 h. In adsorption studies with leaching solutions obtained under optimum conditions, a commercial ion exchange resin (Lewatit MonoPlus SP112) and bio-based microcapsules (chabazite and chitosan) were evaluated for La removal. The effects of adsorbent dosage, pH, temperature, and contact time were systematically investigated. The results show that the commercial resin provides rapid and almost complete La removal, while the microcapsules exhibit slower kinetics due to their heterogeneous structure. Overall, the integrated SRWL-adsorption approach provides an effective way to enrich REEs and recover La from red mud, highlighting the potential for the utilization of industrial wastes.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 10","pages":"9089 - 9108"},"PeriodicalIF":2.3,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
