“…The enhancement of mechanical properties has consistently been a focal point in the research of Mg alloys, despite their numerous advantageous characteristics. The focus of some endeavors to enhance the mechanical properties lies in plastic deformation, such as rolling, extrusions and forgings (Han et al, 2024;Li et al, 2024aLi et al, , 2024bLü et al, 2024). The rolling process is a widely used treatment method that effectively controls the microstructure and enhances the properties of Mg alloys through manipulation of process parameters, such as rolling temperature and cumulative rolling reduction.…”

Purpose The impact of rolling on the performance of micro arc oxidation (MAO) coatings on ZM5 alloy has been underreported. The purpose of this study is to explore the correlation between rolling and the failure mechanism of MAO coatings in greater depth. Design/methodology/approach The influence of rolling on the corrosion and wear properties of MAO coating was investigated by phase structure, bond strength test (initial bond strength and wet adhesion), electrochemical impedance spectroscopy and wear test. The change of the surface electrochemical properties was studied by first principles analysis. Findings The results showed that the MAO coating on rolled alloy had better corrosion and wear resistance compared to cast alloy, although the structure and component content of two kinds of MAO coating are nearly identical. The difference in interface bonding between MAO coating and Mg substrate is the primary factor contributing to the disparity in performance between the two types of samples. Finally, the impact of the rolling process on MAO coating properties is explained through first-principle calculation. Originality/value A comprehensive explanation of the impact of the rolling process on MAO coating properties will provide substantial support for enhancing the application of Mg alloy anticorrosion.

“…The elements of Ca and Gd added into Mg-3Al also decrease yield strength anisotropy due to weakened basal texture [19]. In recent years, different deformation methods are also used to weaken the texture and yield strength anisotropy [20][21][22][23][24]. Among them, cross rolling (CR), whose rolling direction varies 90° during each pass, is an effective way to modify the texture compared with UR.…”

The unidirectional rolled Mg-Zn-Gd sheet usually exhibited non-basal texture with two peaks whose tilting angle were about 42° from normal direction to transverse direction (TD), which would cause the mechanical anisotropy. In this study, multi-cross rolling followed by annealing was used to tailor the texture and mechanical anisotropy for Mg-Zn-Gd alloy. With increasing annealing temperature, the rolled basal texture with two peaks gradually transformed into the circle texture with multi-peaks. In order to figure out different texture components evolution during annealing, the basal texture, R-texture and T-texture component were defined and studied. The results showed that the change of R-texture and T-texture component was asynchronous with increasing annealing temperature from 250 to 400 °C. The tilting angle of R-texture component increased slightly, while the tilting angle of T-texture component increased obviously, and this phenomenon was attributed to the preferential nucleation at grain nucleation stage rather than preferential grain growth. The yield strength along TD was more sensitive to annealing temperature compared with that along rolling direction (RD), resulting in different descending slopes and yield strength anisotropy with increasing annealing temperature. Annealing at 300 °C was the best annealing temperature due to low yield strength anisotropy, moderate strength and good elongation among these annealing temperatures. The Schmid factor for basal slip indicated that the activity of basal slip along RD increased slightly, while that along TD increased obviously with increasing annealing temperature from 250 to 400 °C, which should be caused by the asynchronous change of R-texture component and T-texture component, consequently resulting in the transformation from isotropic yield strength to anisotropic yield strength.

“…[ 4,9 ] Therefore, improving the rolling forming performance, through advance rolling technology, and further obtaining the magnesium alloy sheet with excellent mechanical property is an urgent task. At present, the rolling methods mainly include cumulative overlapping rolling, [ 10–12 ] asymmetric rolling, [ 13,14 ] equal‐diameter angular rolling [ 15–18 ] cross rolling, [ 19,20 ] etc. In our previous research, it is found that the online heating rolling technology has the characteristics of high efficiency and immediacy heating, which reduce energy consumption and simplify the operation process, leading to the decrease in the tendency of the edge cracking of the rolling sheet.…”
