Aluminum and Magnesium Alloys, Composites, and Friction Stir Processing
This community investigates the development, joining, and surface treatment of lightweight structural metals—primarily aluminum and magnesium alloys—and the composite materials derived from them. The work focuses on optimizing mechanical strength, corrosion resistance, and microstructural integrity for applications in aerospace, automotive, and general structural engineering.
The research centers on specific alloy systems, such as AZ31 magnesium and 7075 aluminum, and their behavior under heat treatment and deformation. A significant portion of the work involves friction stir welding and processing, a solid-state joining technique that avoids the defects associated with melting. Other recurring themes include the creation of metal matrix composites reinforced with particles or fibers, the application of plasma electrolytic oxidation and micro-arc oxidation for protective coatings, and the detailed analysis of microstructural evolution during hot deformation. Finite element modeling is frequently used to predict these mechanical and corrosion behaviors.
The community is most heavily represented in research tracked for aluminium, accounting for 34.2% of all aluminium research, and magnesium, accounting for 23.7% of all magnesium research. These two elements also constitute the largest share of the community's total paper count, with 10,978 and 17,862 papers respectively.
The community comprises 87,137 papers, published most frequently in Materials Science and Engineering: A, Journal of Alloys and Compounds, and Materials Science Forum.
Recent work continues to focus on the annual review of magnesium alloy advancements, the application of wire-based friction stir additive manufacturing for aluminum-matrix composites, and the development of high-temperature oxidation resistance in magnesium alloys through grain boundary modulation.
