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.

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
