Research on Thermoforming Process of WE43 Rare Earth Magnesium Alloy Plate

To investigate the rheological behavior of WE43 magnesium alloy sheets at various hot forming temperatures(Room temperatureཞ400 ℃), uniaxial thermal tensile tests were conducted using a Gleeble-3800 thermal simulation system. This study yielded critical mechanical properties, including yield strength, tensile strength, and elongation, across a spectrum of hot forming temperatures. True stress-strain curves were subsequently plotted to visualize the alloy's performance under different thermal conditions. Microstructural analysis of the fracture surfaces revealed a correlation between increasing temperature and enhanced plasticity in WE43 alloy sheets. Further examination using X-ray diffraction (XRD) and microhardness testing on specimens subjected to various thermal tensile conditions confirmed a strong interdependence between microhardness, plastic properties, and grain structure evolution. The comprehensive dataset generated from this study provides crucial input for subsequent numerical simulations and orthogonal experiments on the hot-forming process of WE43 alloy sheets. These findings contribute significantly to our understanding of the material's behavior under hot forming conditions and will inform future process optimizations and alloy development strategies. This research not only elucidates the temperature-dependent mechanical properties of WE43 alloy sheets but also establishes a foundation for advanced modeling and experimental design in the field of magnesium alloy processing.
