“…However, the deformation of Mg alloys restricts their applications, owing to a hexagonal close-packed (HCP) structure which has insufficient independent slip systems. There has been a great deal of research on promoting the structure density, reducing the internal defects, and optimizing the mechanical properties and corrosive behavior of as-cast magnesium alloys by extrusion deformation processes [ 2 , 3 , 4 , 5 , 6 , 7 ]. Extrusion forming technologies can maximize the plastic potential of Mg alloys by applying three-dimensional compressive stress which can effectively refine grains.…”

“…Magnesium alloys have been widely applied in various fields, including engineering, transportation, aerospace and biomedical industries, owing to their low density (1.7 to 2.0 g/cm 3 ), high specific strength, superior damping performance, excellent biosafety, complete degradability and recyclability [1]. However, the deformation of Mg alloys restricts their applications, owing to a hexagonal close-packed (HCP) structure which has insufficient independent slip systems.…”

Magnesium and magnesium-based alloys are widely used in the transportation, aerospace and military industries because they are lightweight, have good specific strength, a high specific damping capacity, excellent electromagnetic shielding properties and controllable degradation. However, traditional as-cast magnesium alloys have many defects. Their mechanical and corrosion properties cause difficulties in meeting application requirements. Therefore, extrusion processes are often used to eliminate the structural defects of magnesium alloys, and to improve strength and toughness synergy as well as corrosion resistance. This paper comprehensively summarizes the characteristics of extrusion processes, elaborates on the evolution law of microstructure, discusses DRX nucleation, texture weakening and abnormal texture behavior, discusses the influence of extrusion parameters on alloy properties, and systematically analyzes the properties of extruded magnesium alloys. The strengthening mechanism is comprehensively summarized, the non-basal plane slip, texture weakening and randomization laws are comprehensively summarized, and the future research direction of high-performance extruded magnesium alloys is prospected.

In order to study the strengthening effect of Mg–X (X = Zn, Ag) alloys, solid solution structures of Mg54, Mg53X1 and Mg52X2 (X = Zn, Ag) with atomic contents of 1.8 at.% and 3.7 at.% were established, respectively. The structural stability, tensile properties and electronic properties were investigated by first-principles simulation. The calculated results of cohesive energies show that all solid solution structures were stable under different tensile strains, and Mg52Ag2 had the best stability. The results of tensile tests show that Zn and Ag atoms promoted the Mg-based alloy’s yield strength and tensile strength. In addition, through comparative analyses, we have demonstrated that the tensile property of Mg-based alloys was also affected by solid solubility. Finally, the electronic density of states (DOS) and electron density difference of several solid solution structures were analyzed.
