Abstract

We fabricated a lean Mg-1.52mass%Zn-0.09mass%Ca alloy sheet having a unique layered heterogeneous microstructure, which consisted of a recrystallized surface-layer and an internal-layer with non-recrystallized grains. An excellent 0.2 % proof stress (PS) and limiting dome height (LDH) were simultaneously achieved. The PS along the rolling direction and LDH reached 263 MPa and 7.4 mm, respectively. The key factor was a degree of recrystallization, and the good LDH was obtained with the PS when the depth of the recrystallized region was ∼100 μm, establishing a new design guidance for the development of strong and formable Mg alloy sheets for automotive sheet applications.

具有层状非均匀组织的强成形Mg-Zn-Ca合金板材

制备了一种具有独特层状非均匀组织的mg -1.52质量% zn -0.09质量%Ca合金薄板，该薄板由表层再结晶和内层非再结晶晶粒组成。同时获得了0.2%的抗应力（PS）和极限穹顶高度（LDH）。沿轧制方向的PS和LDH分别达到263 MPa和7.4 mm。再结晶深度为~ 100 μm时，获得了较好的LDH，为汽车用强成形镁合金板材的开发提供了新的设计指导。
