Special Issue Information

Dear Colleagues,

Recently, the increased environmental concerns and the rising costs of oil have again made Magnesium and Aluminum alloys the material of interest for many industrial fields, such as automobile, aerospace, railway, shipbuilding and marine, because of their low density, high specific strength, superior mechanical and physical properties, as well as processability and recyclability. Since the forming of the microstructure depends on the specific of the forming methods, which directly affects further mechanical and physical properties of the material, it is important to understand how to control the microstructure forming of the Magnesium and Aluminum Alloys by forming methods and heat treatment. Therefore, this Special Issue aims to present the latest research related to heat treatment and forming of Magnesium and Aluminum Alloys, including alloy casting, extrusion and deformation, joining and machining, additive manufacturing, heat treatment, microstructure evolution and mechanical properties.

Laser-arc hybrid welding of AZ31B magnesium alloy was carried out in this paper, and the effects of welding parameters (laser power, welding speed, welding current) on weld formation, microstructure evolution and mechanical property were studied. The results showed that laser-arc hybrid welding can inhibit the undercut defect during laser welding on the one hand, and enhance the arc stability on the other hand. The penetration depth and width showed no significant relation with the total heat input, but were linear related to the laser heat input and the arc heat input, respectively. The average grain size of the equiaxed grains was closely related to the heat input. The higher the heat input was, the larger the grains. The optimized welding parameters were laser power of 3.5 kW, welding speed of 1.8 m/min and welding current of 100 A. In this case, the weld was free of undercut and pores, and the tensile strength and elongation rate reached 190 MPa and 12%, respectively. Full article
