| Abstract | Room-temperature forming of Mg alloy sheets is desirable over warm forming to mitigate machining hazards, lubricant degradation, and energy consumption. This study enhances the drawability of rolled Mg–3Al–1Zn (AZ31B) alloys at room temperature through in-plane compaction. Due to a limiting drawing ratio (LDR) below ~1.3, typical deep drawability parameters (n-value, r-value, tensile strength) could not be used. Instead, the activation of prism texture in surface sheets and the suppression of basal texture effectively accommodated thickness strain, improving drawability. In-plane pre-compression along angles relative to the rolling direction (RD) — 0° (RD), 30°, 45°, 60° and 90° (transverse directions, TDs) — with strains of 0.06 or 0.08 further enhanced formability. This process increased circumferential strain from 0.010 in as-received material to 0.227 in 6.0% pre-compressed specimens, demonstrating a significant improvement in room-temperature formability for AZ31B magnesium-alloy sheets. |
