Summary: High-pressure torsion (HPT) is a successful technique for refining alloy grains, improving the mechanical properties of magnesium alloys, and exhibiting superplastic behavior. In this study, AZ80 magnesium alloy was processed by HPT and demonstrated superplasticity at a testing temperature of 573 K, as well as low-temperature superplasticity. The dominant mechanism for superplastic flow is grain boundary sliding.

Summary: The RBE process shows potential in producing high-quality cup-shaped AZ80 magnesium alloy pieces through controlling grain size and dynamic recrystallization fraction by adjusting rotating revolutions and processing temperature. The refined microstructure and weakened texture in RBE samples contribute to improved quality and performance of the cup-shaped samples.

Summary: This study investigates the deformation mechanisms and differential work hardening behavior of rolled AZ31 magnesium alloy sheets under biaxial loading. The results show that biaxial loading leads to higher macroscopic work hardening rates compared to uniaxial loading, with low activation of non-basal slip and activation of contraction twinning at larger plastic strain.

Summary: Die forging is a processing method that can produce nearly finished products and enhance mechanical properties of alloys. This study focused on the microstructure and stress-strain state of a stepped shaft made from Mg-8Al-0.5Zn magnesium alloy through isothermal die forging. The metal rheological behavior and microstructure evolution mechanism during die forging of AZ80 alloy were discussed.

Summary: This study investigated the effect of ultrasonic processing (UP) on the hot rolling deformation performance of as-cast AZ80 alloy through experiments and simulations. The results show that UP can refine grains, eliminate dendrites, and improve the basal texture, contraction twin, and double twin content. The sheet without UP is prone to cracking during rolling, while the sheet with UP has fewer cracks. The simulation results indicate that the as-cast AZ80 with UP requires lower stress and has lower damage value during the rolling process.

Summary: In this study, the addition of 1.5 wt% La-rich Mish Metal (LaMM) to AZ80 magnesium alloy was investigated for its impact on microstructure evolution and texture development of the wheel hub. The results showed that LaMM greatly improved the refinement ability and deformation uniformity of AZ80 wheel hub, leading to a higher volume fraction of dynamic recrystallization (DRX) grains. The texture of the wheel hub weakened along the forming direction due to increasing strain and DRX degree. The hardness values of AZ80-LaMM wheel hub were larger and more uniform, attributed to the inhibition of grain growth by rare earth (RE) phases.

Summary: The study found that using different aging temperatures affects the distribution and volume fraction of Mg17Al12 precipitates in AZ80 magnesium alloy, as well as the corrosion behavior of the alloy. Lower aging temperature results in higher corrosion resistance, which is correlated with the number density of Mg17Al12 precipitates.

Summary: This study investigated the effect of surface indentation size on the corrosion behaviour of MAO coated AZ80 magnesium alloy. Various techniques, including laser confocal microscope, scanning electron microscope, X-ray diffractometer and electrochemical test, were used to study the corrosion process and damaged coatings. The results showed that the corrosion current density increased when the MAO coating was damaged with a certain impact height. Furthermore, the corrosion mechanism for coatings with different indentation sizes was clarified.

Summary: The precipitation evolutions of AZ80 magnesium alloy involve both discontinuous precipitation and continuous precipitation during non-isothermal and isothermal processes. The precipitation behavior is influenced by thermal history, holding temperature, and time. At lower temperatures, massive DP and CP are gradually formed to equally strengthen the alloy, while at higher temperatures, Ostwald coarsening occurs, leading to a slight softening of the alloy.

Summary: The microstructure, anisotropy in tensile strength and tensile creep resistance of the ring rolled AZ80-Ag alloy were investigated. It was found that the alloy exhibited higher strength along the rolling direction and higher creep resistance along the transverse direction. Creep mechanisms involving diffusional creep and dislocation climb were identified during the creep of the alloy.

Summary: This study demonstrates that the microstructure and mechanical properties of AZ80 magnesium alloy can be significantly improved by adding nanoparticles and increasing the number of DECLE passes. The grain size decreases significantly with the increase in pass numbers, leading to improved hardness and tensile strength.

Summary: This paper investigates the effect of La addition on the Al-RE phase in Mg-Al-Zn-Ce magnesium alloy. The results show that adding La can change the morphology of the Al11RE3 phase and a transformation mechanism is proposed. La replaces part of Ce in the Al11Ce3 phase, resulting in the formation of Al11RE3 phase. In the Al11RE3 phase, La doping leads to lattice distortion and accelerates the growth rate in a specific direction, forming a tubular structure.

Summary: The simulation of service performance of magnesium alloy wheel hub was conducted by studying the impact of surface defect size on the corrosion resistance of a calcium phosphate conversion coated AZ80 magnesium alloy. The study found that the size of surface defects influenced the corrosion resistance of the coating and the corrosion initiation area. The coating did not provide protection for an indentation larger than 2.7 mm.

Summary: The corrosion resistance of AZ80-xNd (x = 0, 0.5, and 1.0 wt.%) magnesium alloys is significantly affected by the rare earth neodymium (Nd) and heat treatment. The appropriate Nd content reduces the corrosion rate, but excessive Nd content decreases the corrosion resistance. The corrosion rate of solution treated alloys is higher than that of as-cast alloys, while the corrosion rate of aged alloys is the lowest. Rod-shaped Al3Nd phase and block-shaped Al2Nd phase effectively improve the corrosion resistance of the alloy.
