The tensile strength increased with increasing welding energy, peaked at a welding energy of 1000 J, and then decreased due to the formation of an increasingly thick diffusion layer mainly containing Al<sub>12</sub>Mg<sub>17</sub> intermetallic compound at higher energy levels. The peak tensile lap shear strength attained at 1000 J was attributed to the optimal inter-diffusion between the magnesium alloy and softer AA1230-clad Al layer along with the presence of ‘fishhook’-like mechanical interlocks at the weld interface and the formation of an indistinguishable intermetallic layer. The dissimilar joints welded at 1000 J also exhibited a longer fatigue life than other Mg-Al dissimilar joints, suggesting the beneficial role of the softer clad layer with a better intermingling capacity during USW. While the transverse-through-thickness (TTT) failure mode prevailed at lower cyclic loading levels, interfacial failure was the predominant mode of fatigue failure at higher cyclic loads, where distinctive fatigue striations were also observed on the fracture surface of the softer clad Al layer. This was associated with the presence of opening stress and bending moment near the nugget edge despite the tension-tension lap shear cyclic loading applied.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"1 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most researched biodegradable metal is magnesium (Mg), followed by zinc (Zn) and iron (Fe). However, due to the limitations of in vivo experiments and the complex component of the gastrointestinal fluid, their degradation mechanisms in such an environment are still ambiguous. In this work, the human duodenal fluid (HDF) was used to investigate their in vitro degradation behaviors, with a simulated duodenal fluid (SDF) prepared for the control group based on the HDF ionic composition. After immersion of these metals for 7 days, it is found that HDF shows a stronger pH buffering effect than SDF due to the presence of organics. These organics can also hinder the degradation of metals by affecting their product formation in different ways. On the one hand, the adsorption of organics and their effects on the fluid dominate their degradation inhibition effect on Mg and Zn in HDF. On the other hand, they can hinder the further oxidation of the degradation products of Fe, which is the main mechanism resulting in a lower degradation rate of Fe in HDF rather than in SDF. Among the three metals, Mg unsurprisingly shows the highest degradation rate in both fluids. Interestingly, Zn is nearly immune to degradation in HDF, while it presents typical pitting corrosion in SDF. Compared to their degradation rates in popular pseudo-humoral media (e. g. Hanks’ Balanced Salt Solutions, Dulbecco's modified Eagle's medium) reported previously, Mg degrades faster, and Zn and Fe more slowly in HDF. The higher <em>in vitro</em> degradation rate of Fe than that of Zn is influenced by oxygen and ions in the degradation environment.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"8 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of dynamic recrystallization behavior and slip system activity on texture evolution and mechanical properties of CVCDE Mg alloys with different pre-upsetting amounts were systematically analyzed. The results indicate that the introduction of the pre-upsetting process promotes dynamic recrystallization during the CVCDE process. The recrystallization proportion shows a trend of first rising and then decreasing with the increase of the pre-upsetting amount. Among them, the proportion of recrystallization grains in the U2-CVCDE-formed structural parts is as high as 88.3 %. The average grain sizes of U1-CVCDE, U2-CVCDE, and U3-CVCDE were 6.01 µm, 4.90 µm, and 10.45 µm, respectively. In addition, following U-CVCDE, the pyramidal slip of each forming component consistently maintains a high level of activation and opening and dominates, making more grains deflect in the axial extrusion direction of C to varying degrees, which is conducive to the uniform distribution of stress in more grains during plastic deformation. The synergistic effect of dynamic recrystallization behavior and the high activity of the pyramidal slip system significantly weakened the (0001) basal texture strength, and the maximum basal texture strength showed a gradually decreasing trend, among which the base surface texture strength of U3-CVCDE formed parts was only 9.9. The U-CVCDE process is employed to achieve deep modification of Mg alloy, and excellent comprehensive mechanical properties are obtained; among them, the yield and tensile strength of U2-CVCDE are as high as 243.4 MPa and 317.5 MPa, respectively, and the elongation after breaking is up to 21.3 %.

Moreover, the hydrogen desorption thermodynamics could be improved with the increase of microwave power. The hydrogen release time is shortened by 19.55% with the increase of 20 W microwave power.

In this research, an ZK61 magnesium alloy thin-walled cylindrical component was successfully fabricated by two-step forging, i.e., the pre-forging and final-forging is mainly used for wed and thin-wall formation, respectively. Microstructure and mechanical properties at the core, middle and margin of the web and the thin-wall of the pre-forged and final-forged components are studied in detail. Due to the large strain-effectiveness and metal flow along the radial direction (RD), the grains of the web are all elongated along RD for the pre-forged component, where an increasingly elongated trend is found from the core to the margin of the wed. A relatively low recrystallized degree occurs during pre-forging, and the web at different positions are all with prismatic and pyramid textures. During final-forging, the microstructures of the web and the thin-wall are almost equiaxed due to the remarkable occurrence of dynamic recrystallization. Similarity, except for few basal texture of the thin-wall, only prismatic and pyramid textures are found for the final-forged component.

The specimens were deformed under varying degrees of IPS strain (γ₁₂ = 0.05, 0.10, and 0.15) using a customized jig. Electron backscatter diffraction (EBSD) observations revealed profuse tensile twinning (TTW) even at an IPS strain of 0.05, with its intensity continuously increased as the IPS strain increased. The TTWs progressively engulfed parent grains with increasing shear strain, evolving into an unusual deformation twin morphology. Furthermore, VPSC model predictions confirmed basal slip as the dominant deformation mode at low IPS strains, transitioning to prismatic slip dominance at higher IPS strains. The activity of the TTW mode was significantly higher during the initial stages of IPS strain and saturated to lower values at higher strains. VPSC simulation results also indicated preferential shear accumulation on a single twin system, explaining the phenomenon of a single twin variant engulfing a parent grain. Additionally, the influence of individual slip and twin modes on texture evolution was evaluated through orientation tracking of representative grains at various shear strain increments using VPSC simulation. The simulation results quantitatively highlighted the activities of basal slip, prismatic slip, and tensile twinning, establishing a correlation between texture evolution and the underlying deformation mechanisms.</div></div>","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"13 4","pages":"Pages 1815-1828"},"PeriodicalIF":15.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
