Design, Development and Processing of Aluminium Alloys and Their Composite Materials

Dear Colleagues, 

Aluminium, the most abundant metallic element in the Earth's crust, is one of the most widely used non-ferrous metals in industry, second only to iron and steel in terms of its scope of use because of its good characteristics—low density, high specific strength, workability, and electrical conductivity, superior corrosion resistance, environmental protection and recyclability—and wide range of applications in the aviation, aerospace, construction engineering, and transportation fields.

The design, development, and processing of aluminium alloys and their composites occupy a pivotal position in modern industry to further enhance their toughness, wear resistance, and shear properties. In the case of aluminium alloy composites, researchers have effectively improved the materials’ toughness and wear resistance by introducing various reinforcing phases, such as ceramic particles, carbon nanotubes, and graphene. In this process, the nature, content, and distribution of the reinforcing phase, as well as its interfacial bond strength and wettability with the metal matrix, are the key factors determining the mechanical properties of metal matrix composites. Therefore, the ideal reinforcing phase not only needs to significantly enhance the specific properties of the metal matrix but also have a high degree of stability to avoid violent reactions with the matrix at high temperatures and ensure good metal matrix wettability in order to achieve an effective combination between the two. In addition to material design and development, the processing technology of aluminium alloys and their composites is also key to enhancing their material performance and application scope. Traditional processing methods such as casting, forging, and rolling meet these needs but have limitations, leading researchers to explore new technologies, such as powder metallurgy, EDM, and superplastic forming, to achieve higher precision, lower energy consumption, and better environmental performance.

This Special Issue will focus on the design, development, and processing technologies of aluminium alloys and their composite materials. We warmly invite you to contribute full papers, newsletters, and reviews on the latest developments and research results on this topic.
