“…Fewer defects in the Mm-adding alloys were also helpful to improve their strength and ductility. Thus, the appropriate Mm addition could effectively improve strength and ductility owing to the solid solution strengthening, refinement strengthening, and the secondary phase strengthening [45][46][47].…”

The effects of small amounts of Ce-rich misch metal (Mm: 0.5, 1.0 and 2.0 wt.%) addition on the microstructure and tensile properties of as-cast Mg-7Al-3Sn-1Zn wt.% (ATZ731) alloy have been investigated. The addition of Mm restricts the formation of the Mg17Al12 phase but greatly promotes the Al4Mm phase. The proper Mm addition enhances the strength and ductility of ATZ731 alloys at both room temperature (RT) and 175 °C. ATZ731 alloys with 1.0 wt.% Mm addition exhibit an advantageous combination strength and ductility, with the ultimate tensile strength (UTS), 0.2% yield strength (YS) and elongation to failure (Ef) at 175 °C of ~148 MPa, ~102 MPa and ~28%, improved by ~14.7%, ~24.3% and ~53.8%, respectively, compared to those of ATZ731 alloy. This enhancement is primarily owing to the refined microstructures and the high thermal stability of Al4Mm at the elevated temperature in contrast with that of the Mg17Al12 phase. The fracture modes are also discussed.

“…10 show that pulse current treatment can reduce the initial texture density of the magnesium alloy (0001) and {10-10} type textures, indicating that the pulse current treatment enhances the activity of basal < a > slips by reducing the texture density. The activities improve the anisotropy [26], thereby improving the micro-forming properties of AZ31 magnesium alloy. Tiwaria et al [17] used a SHTB to study the deformation behavior of an aluminum-zincmagnesium-copper alloy at a high strain rate and found that the overall texture of the alloy weakened with the increase of the strain rate, indicating that high strain rate (LSF) can reduce the texture strength of the material.…”

This study adopted a novel pulse current-assisted laser shock AZ31B sheet micro-forming method (EP-LSF). The mechanism of improving the formability of AZ31B Magnesium Alloy by pulse current assisted laser shock forming and the reason of improving the corrosion resistance were studied for the first time. Through laser shock free bulging experiment, tensile test, optical microscope (OM), and X-ray diffraction, the change in formability was studied. After pulse current assisted laser shock forming, the forming height of AZ31B magnesium alloy increases by 28.8%, the thinning rate decreases by 6.7%, and the strain rate sensitivity coefficient increases to 0.1452. The results show that the decrease of grain size and texture density is the reason why EP-LSF can further improve the formability of AZ31B magnesium alloy. The changes in corrosion resistance were studied by scanning electron microscopy and electrochemical tests. The results show that after EP-LSF, the corrosion current density of AZ31 magnesium alloy decreased, and the electrochemical impedance increased, indicating that this method further improved the corrosion resistance.

“…Mg alloys have attracted many attentions to be used for fabrication of lightweight components in the automobile, electronics and aircraft industries due to their low density and high specific strength [1]. However, there was a strict limit to processing and forming of Mg alloys for their ductility and formability at room temperature (RT) were generally low, which was caused by insufficient slip systems operating during the plastic deformation [1,2]. Rolled Mg alloys sheets, as main raw materials before further processing and forming, were usually characterized by a strong basal texture, which would result in an anisotropic plastic deformation and a deterioration formability during subsequent forming processes [2,3].…”

In this study, a method of corrugated width limit alignment processes (CWLA) was applied to pre-twin in hot-rolled Mg alloy sheets. The microstructure evolution and mechanical properties of the CWLA sheets were studied. The results demonstrated that the grain orientation was transformed from strong basal texture to RD-rotated texture after CWLA treatment and up to 22.2% of {10-12} tensile twin boundaries were produced in the microstructure. The 60 ± 5° < 10-10 > twin variant pairs were dominant in the twinned microstructure. Two kinds of dynamic recrystallization (DRX) mechanism, i.e., continuous DRX (CDRX) at low-temperature CWLA and the discontinuous DRX (DDRX) at high-temperature condition were observed. After post-annealing, the twin-induced static recrystallization (SRX) and abnormal grain growth were observed in the CWLA samples, and most twin boundaries were retained. After CAWL for 60 min at 300 °C and post annealing, an improvement on plasticity and strength were achieved with 55% increment for uniform elongation (UE) and 10% increment for ultimate tensile strength (UTS).
