“…Because Mg-based alloys have a high strength-to-weight ratio, they are extensively used in the automobile industry [119]. Thus, the fuel consumption of the vehicle is reduced using them [1][2][3][4]6,120]. On the other hand, these alloys possess suitable biocompatibility and are applicable as a biomaterial.…”

“…Magnesium (Mg)-based alloys are widely used in the industries of automotive, aerospace, electronics, transportation, and so on [1][2][3][4][5]. The cause of this is related to low density (i.e., low weight), high shock absorption, high damping, good electromagnetic shielding, high specific strength, and good hot formability [2][3][4]6,7]. On the other hand, the casting of these alloys is cost-effective, and they can be recycled [1,2,7,8].…”

“…It is quite obvious that grain refinement results in an improvement in strength and toughness simultaneously. Accordingly, the best method for increasing them as well as formability in Mg-based alloys is to make grain refinement and randomized basal texture (i.e., modification of strong basal texture) [6].…”

“…Thus, FSW/FSP treatment does not need the material to be pre-heated, and it is carried out at room temperature [15,[27][28][29]32]. Generally, by performing FSW/FSP, the microstructure and texture of the material are modified without decreasing the fracture strength [2,6,27]. FSW/FSP causes a grain refinement in SZ, and on the other hand, a uniform microstructure is obtained [14,23,27,28,[33][34][35][36].…”

“…In this regard, Chang et al [23,54] employed liquid nitrogen-cooled FSP to fabricate AZ31 alloy with a fine-grained structure [55], while Yuan et al [56] employed a copper backing plate to escalate the cooling rate throughout FSP of AZ31 alloy, presenting the UFG with formidable basal texture, which has a significant effect on mechanical performance [55]. It has been shown that nano-grains can be formed by the supercooling path [6,[57][58][59]. Chai et al [60] examined the microstructure and superplastic tensile performance of as-cast AZ91 plate conventional FSP (treated in the air) and immersed FSP (treated in water, SFSP) alloys.…”

Friction stir welding (FSW) and friction stir processing (FSP) are two of the most widely used solid-state welding techniques for magnesium (Mg) and magnesium alloys. Mg-based alloys are widely used in the railway, aerospace, nuclear, and marine industries, among others. Their primary advantage is their high strength-to-weight ratio and usefulness as a structural material. Due to their properties, it is difficult to weld using traditional gas- or electric-based processes; however, FSW and FSP work very well for Mg and its alloys. Recently, extensive studies have been carried out on FSW and FSP of Mg-based alloys. This paper reviews the context of future areas and existing constraints for FSW/FSP. In addition, in this review article, in connection with the FSW and FSP of Mg alloys, research advancement; the influencing parameters and their influence on weld characteristics; applications; and evolution related to the microstructure, substructure, texture and phase formations as well as mechanical properties were considered. The mechanisms underlying the joining and grain refinement during FSW/FSP of Mg alloys-based alloys are discussed. Moreover, this review paper can provide valuable and vital information regarding the FSW and FSP of these alloys for different sectors of relevant industries.

Plates with rib-web structure of magnesium alloys can hardly fabricated through conventional method. In this work, the variable circular channel angular extrusion (VCCAE) combined extrusion and severe plastic deformation is proposed, in which billet undergoes severe deformation at several variable circular angular channel. The FE model for VCCAE of scaling plate with ribs is established and the experimental set up is designed. The feasibility of the novel process and the accuracy of the FE model are validated by the simulations and experiments. Stress state and the effective strain distribution in longitudinal section and cross section are analyzed. The results show that stress and strain distribution in longitudinal section is extremely inhomogeneous, and obvious stress concentration at the shear plane is founded. The microstructure in angular region is more uniform and ner, which validate that the severe shear deformation induced by the angular channel in the VCCAE process could promote the deformation uniformity and grain re nement. The results of numerical simulation and experiments demonstrate that the VCCAE process proposed in this paper is feasible and it has great potential to manufacture highperformance plate with ribs.
