“…However, the simulation results of the maximum width of the molten pool and the maximum width of the heat-affected zone on the steel side are equivalent to the actual size. Therefore, the simulation model is reasonable for calculating and analyzing the temperature field of steel and magnesium laser welding [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

The effects of laser welding parameters on the interface microstructure of AZ31B magnesium alloy and 304 stainless steel were investigated. After welding, a scanning electron microscope and ultra-depth of field microscope were used to observe the microstructure of the welded material, to analyze the effects of power on the interface morphology. The simulation of laser welding of magnesium and steel was carried out by the COMSOL software. The results showed that when the power was 15 W–20 W, the temperature did not reach the melting point of magnesium alloy, there was MgO at the welding, and the interface had poor connection strength. When the power was 35 W–50 W, the temperature reached or even exceeded the boiling point of magnesium alloy, and the interface formed hot cracks, pores, and oxides and had poor joint strength. When the power was 25 W–30 W, the temperature was between the melting point and boiling point of magnesium, and the interface had excellent connection strength.

Cathodic electrodeposition (CED) was used to coat the cast magnesium alloy Mg-9Al-1Zn-xRE with aluminum powder and epoxy. Immersion and salt spray tests (ASTM B117) at room temperature for a total of 240 hours have been performed to assess the corrosion performances of AZ91D magnesium alloy. At each 24-hour interval, the samples were checked for any damage or deterioration of the coating surface morphology. The X-ray diffraction (XRD) analysis confirmed the phases, and scanning electron microscopy (SEM) with EDS analysis confirmed the phase composition. The electrochemical results show that CED epoxy coatings have superior adhesiveness and corrosion resistance compared to powder-coated aluminum and cast magnesium. The salt spray and immersion test results also confirm that CED epoxy coating exhibits good corrosion resistance.

“…MgÀLi alloy has the characteristics of low density, high specific strength and specific modulus, and excellent electromagnetic shielding performance, making it widely used in the fields of aerospace, automotive, electronics, and national defense. [1,2] However, the strength of the MgÀLi alloy is relatively low, which greatly limits its rapid development and wide application. Therefore, strengthening of the MgÀLi alloy has become a research focus.…”

The influence of Al, Y, and Zn additions on the microstructure and mechanical properties of Mg−3Li alloy is investigated. It is revealed that Al and Y form the Al2Y phase that can refine α‐Mg grains. Y and Zn form the 18R long‐period‐stacking‐ordered (LPSO) structure phase that can coordinate deformation. In addition, the formed SFs can hinder dislocation slip. However, the Mg24Y5 phase weakens the grain boundaries. After solid solution at 520 °C, the Al2Y phase and LPSO phase do not change. The Mg24Y5 phase gradually disappears, SFs decrease, and the grain of the alloy grows. After subsequent hot rolling at 350 °C, the grains and LPSO phase are gradually elongated along the rolling direction, and the LPSO phase is twisted. SFs increase and the grain of the alloy is refined. In addition, MgY phase is precipitated inside the matrix. With the rolling reduction of 70%, the Mg−3Li−1Al−4Y−1Zn alloy possesses the ultimate tensile strength (UTS) and elongation (EL) values of 287 MPa and 5.2%.
