The total strain amplitudes (Δε_t/2) were 0.4%, 0.5%, 0.6%, 0.7% and 1.0%. Detailed microstructure evolution was characterized by scanning electron microscope (SEM), electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM). The results showed that plastic strain amplitude decreased with the increasing cycle number in T4 alloy, which is due to the dense persistent slip bands (PSBs) and dynamic precipitates hindering &lt;a&gt; dislocation slip. In contrast, the plastic strain amplitude increases gradually in T6 alloy, which is attributed to the enhanced activation of pyramidal slip. The low-cycle fatigue life of T6 alloy with larger fatigue ductility coefficient is longer than that of T4 alloy. The Coffin-Manson model can accurately predict the fatigue life of T4 and T6 alloys compared to Jahed-Varvani (JV) energy model. For T4 alloy, the fatigue damage mechanism was dominated by basal slip. For T6 alloy, the enhanced pyramidal slip plays an important role to accommodate plastic deformation.</p></div>","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":null,"pages":null},"PeriodicalIF":15.8,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213956722002481/pdfft?md5=8f308b04a51005249f5f4cd0b7f59beb&pid=1-s2.0-S2213956722002481-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45455566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Layered Double Hydroxides (LDHs), particularly Mg-based LDHs, rank among the most prevalent two-dimensional materials utilized in separation processes, which include adsorption, extraction, and membrane technology. The high popularity of Mg-based LDHs in separation applications can be attributed to their properties, such as excellent hydrophilicity, high surface area, ion exchangeability, and adjustable interlayer space. Currently, polymer membranes play a pivotal role in semi-industrial and industrial separation processes. Consequently, the development of polymer membranes and the mitigation of their limitations have emerged as compelling topics for researchers. Several methods exist to enhance the separation performance and anti-fouling properties of polymer membranes. Among these, incorporating additives into the membrane polymer matrix stands out as a cost-effective, straightforward, readily available, and efficient approach. The use of Mg-based LDHs, either in combination with other materials or as a standalone additive in the polymer membrane matrix, represents a promising strategy to bolster the separation and anti-fouling efficacy of flat sheet mixed matrix polymer membranes. This review highlights Mg-based LDHs as high-potential additives designed to refine flat sheet mixed matrix polymer membranes for applications in wastewater treatment and brackish water desalination.</p></div>","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":null,"pages":null},"PeriodicalIF":15.8,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213956724002020/pdfft?md5=0de030768f6ef34deb541c4ec748e711&pid=1-s2.0-S2213956724002020-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141630759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnesium (Mg) alloys are highly valued for their low weight, making them increasingly important in various industries. Researchers focusing on enhancing the characteristics of Mg alloys and developing their Metal Matrix Composites (MMCs) have gained significant attention worldwide over the past decade, driven by the global shift towards lightweight materials. Friction Stir Processing (FSP) has emerged as a promising technique to enhance the properties of Mg alloys and produce Mg-MMCs. Initially, FSP adapted to refine grain size from the micro to the nano level and accelerated the development of MMCs due to its solid-state nature and the synergistic effects of microstructure refinement and reinforcement, improving strength, hardness, ductility, wear resistance, corrosion resistance, and fatigue strength. However, producing defect-free and sound FSPed Mg and Mg-MMCs requires addressing several variables and their interdependencies, which opens up a broad range of practical applications. Despite existing reviews on individual FSP of Mg, its alloys, and MMCs, an attempt has been made to analyze the latest research on these three aspects collectively to enhance the understanding, application, and effectiveness of FSP for Mg and its derivatives. This review article discusses the literature, classifies the importance of Mg alloys, provides a historical background, and explores developments and potential applications of FSPed Mg alloys. It focuses on novel fabrication methods, reinforcement strategies, machine and tool design parameters, material characterization, and integration with other methods for enhanced properties. The influence of process parameters and the emergence of defects are examined, along with specific applications in mono and hybrid composites and their microstructure evolution. The study identifies promising reinforcement materials and highlights research gaps in FSP for Mg alloys and MMCs production. It concludes with significant recommendations for further exploration, reflecting ongoing advancements in this field.</p></div>","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":null,"pages":null},"PeriodicalIF":15.8,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213956724002032/pdfft?md5=d54de57a122ac104517c3268ec4163a6&pid=1-s2.0-S2213956724002032-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141630682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
