Special Issue Information

Dear Colleagues,

The use of non-ferrous metals predates the Middle Ages, but it was the Industrial Revolution and the subsequent impact of the transportation revolution that tremendously pushed demand for their use. The development of the airplane industry, the commercialization of automobiles, and the mass production of durable and recreational consumer goods fueled this increased demand. The applications of non-ferrous metals provide technological advantages and cost savings that are indispensable in today's world. In fact, in some cases, they form far better materials than iron and steel and have replaced them to a great extent. Most industries, including aviation, aerospace, automobiles, machinery manufacturing, electricity, communications, construction, and home appliances, rely on the use of non-ferrous metal materials. Therefore, non-ferrous metals are the basic materials for the development of the national economy and the main objects in the research world.

In this Special Issue, we welcome articles that focus on non-ferrous metals and their processing, characterization, and applications. The papers presented in this Special Issue will give an account of the scientific and technological state of the art of non-ferrous metals (see the Keywords/Topics below) in 2024. Contributions to this Special Issue are highly valued and appreciated. We invite you to contribute research work that relates to the benefits of non-ferrous alloys in today's world.

Aluminium alloys have a wide range of applications, mainly due to their advantageous strength-to-weight ratio, denoted as specific strength and corrosion resistance. In recent decades, there has been a notable surge in the usage of recycled alloys, attributed to their reduced production costs and emissions. One of the conditions for secondary production is the optimal sorting of used scrap. Once the aluminium scrap has been melted, it is tough to reduce the content of the various additives. Copper is the primary alloying element in some aluminium alloys, which leads to an increased amount of copper in the aluminium scrap. Therefore, it is important to investigate its effect on the properties of aluminium alloys in which it is not commonly present. For this reason, this paper is concerned with the influence of copper on the microstructure and properties of the secondary aluminium alloy AlZn10Si8Mg. Specifically, it compares two melts of self-hardening AlZn10Si8Mg alloys differing in copper content (0.019% and 1.72%). A complex quantitative and metallographic analysis by optical and electron microscopy has been performed. Mechanical properties were investigated by tensile test, Brinell hardness, and Vickers microhardness measurements. The corrosion resistance of the individual melts was verified by the Audi test.

In this paper, the electron backscatter diffraction (EBSD) technique was used to analyze the dynamic recrystallization (DRX), twinning, slip behavior, and texture evolution during forging and subsequent extruding deformation. The results show that, as the degree of strain increased (forging to extruding), the degree of DRX increased, and the DRX mechanism changed from discontinuous DRX (DDRX) during forging to DDRX and continuous DRX (CDRX) during extruding. Particle stimulation nucleation (PSN) promoting DRX occurred during deformation. The deformation process mainly produced {10–12} twins (TTW) and played a role in coordinating the deformation. The slip behavior also changed according to an analysis of in-grain misorientation axes (IGMA) results, changing from slip-dominated with a basal <a> slip to co-dominated with multiple slip modes, with the activation of mainly prismatic <a> and pyramidal <c+a> slip. Meanwhile, the strong basal texture at the beginning of the deformation also changed, and the texture strength decreased from 24.81 to 15.56. The weakening of the texture was mainly due to the formation of DRX grains and twins, as the newly formed DRX and twins reoriented. In the later stages of deformation, the activation of prismatic <a> slip and pyramidal <c+a> slip changed the basal texture component. Based on microstructural analysis, the improvement in mechanical properties was due to fine-grain strengthening and load-transfer strengthening. The ultimate tensile strength (UTS) was 370.5 MPa, the yield strength (YS) was 340.1 MPa, and the elongation (EL) was 15.6%. Full article
