| Summary: | The preparation of magnesium (Mg) foils involves complex and labor-intensive rolling processes, along with a significant occurrence of defects such as fractures, which notably escalate production costs. In this study, high-purity magnesium, recognized for its excellent battery performance, was used as the initial sheet. By utilizing online heating rolling equipment and a low-temperature single-pass rolling process, 0.2 mm Mg foils were successfully prepared at different rolling temperatures (25 °C, 100 °C and 150 °C). This study extensively analyzed the deformation behavior of pure Mg foils at various rolling temperatures using techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and electron backscatter diffraction (EBSD). Furthermore, the fracture mechanism of the foils at 200 °C was investigated using high-temperature tensile testing equipment. The study revealed that as the rolling temperature increases from 25 °C to 150 °C, the texture strength of Mg foils gradually decreases. Notably, at a rolling temperature of 200 °C, due to the sharp rise in the temperature of the foil near the roller and the influence of rolling tension, the Mg foil breaks. |
