In this study, NiCoCrAl<sub>0.3</sub>Fe high-entropy alloy with a single-phase FCC structure was prepared using vacuum arc melting technology. The oxidation mechanism of NiCoCrAl<sub>0.3</sub>Fe high-entropy alloy at 1100 °C was investigated during the initial stage of oxidation, and the results indicate that the Al element in the high-entropy alloy preferentially undergoes oxidation, followed by the Cr element. The Al element, which oxidizes preferentially, forms granular Al<sub>2</sub>O<sub>3</sub> due to its content in the alloy being below the critical concentration (16.13%).

In this work, a highly corrosion-resistant coating was fabricated on a magnesium-alloy surface to protect the underlying substrate. Unlike conventional hydrothermal methods, this approach does not improve corrosion resistance by altering the coating’s precursor materials; instead, it focuses on investigating grain behavior at different temperatures to regulate the coating’s corrosion resistance. By extending the heating duration, the coating exhibited increased thickness, grain refinement, and a denser, more ordered arrangement, which effectively blocked corrosive ions and consequently led to a significant improvement in corrosion resistance. To verify corrosion-resistance performance, the as-prepared coatings were immersed in a saturated sodium chloride solution for 15 days; the coatings exhibited almost no corrosion, whereas the magnesium substrate had nearly completely dissolved by day 10. Additionally, when coated samples were immersed in an HCl solution at pH 2 for 15 days, only slight surface corrosion was observed on the coatings. Electrochemical tests indicated that when the heating duration was extended to 5 h, corrosion resistance reached its maximum: the coating’s impedance was six orders of magnitude higher than that of the substrate, and its corrosion current density decreased by five orders of magnitude, consistent with the immersion tests. Here, grain refinement and dense packing played critical roles by reducing porosity and crack density, thereby blocking the ingress of chloride and other corrosive ions.

In recent years, rare earth elements (REEs) have demonstrated great potential for enhancing the performance of Mg alloys, both as alloying elements and in surface modifications. As alloying elements, REEs are effective in melt purification (e.g., reducing harmful impurities like Fe), grain refinement and microstructure regulation, thereby improving the mechanical properties (up to 177% improvement in mechanical strength) and corrosion resistance of Mg alloys (up to 225% reduction in corrosion rate). By incorporation into surface coating, the presence of REEs could not only improve the corrosion resistance, promote cell adhesion and proliferation, but also endow Mg alloys with various biofunctionalizations. This review delves into the roles of REEs in developing novel Mg-based alloys, covering the influence of REEs as alloying elements on performance of biomedical Mg alloys, REEs selection strategies, as well as the surface modification techniques with REEs incorporation. By identifying relevant literatures through systematic searches, the review comprehensively analyzes the internal mechanisms on how REEs impact the microstructure, mechanical properties, corrosion behaviors and biocompatibility of Mg alloys.

The influencing mechanisms of interface microstructure evolution on the mechanical behavior and stamping formability of LMCs were discussed. The researches reveal that the basal texture of the Mg layer in LMCs annealed for 1 h is the weakest. The average Schmidt factor values of {1–100}<11–20>cylindrical and {11–22}<11–2–3>conical slip systems are relatively high, indicating they are easy to start, which is conducive to improving the plasticity of LMCs. As the annealing continues, both the Ti/Al and Al/Mg interface bonding strengths enhance first and then reduce, and the optimal bonding strengths of 47.80 N/mm and 4.24 N/mm are achieved when annealed for 1 h, respectively. Both the ultimate tensile strength and yield strength of LMCs reduce first and then enhance, reaching the minimums of 237.75 MPa and 189.02 MPa when annealed for 1 h, respectively. However, the changes of elongation (EL) and Erichsen value of LMCs are opposite, and they reach the maximum of 3.62% and 4.88 mm after annealing for 1 h, respectively. Crack deflection, tearing and the initiation of secondary microcracks consume energy and are more conducive to stamping. The research results will provide theoretical and experimental basis for the interface regulation behavior of LMCs suitable for stamping forming.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"32 9","pages":"3264 - 3280"},"PeriodicalIF":4.5,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148661934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
