| Abstract Scope |
Magnesium (Mg) components are economically beneficial substitutes for automobile aluminum and steel parts. Mg alloys demonstrating dynamic strain aging (DSA) have been attributed to texture weakening in dilute Mg-RE alloys. The potential of using calcium (Ca) and zinc (Zn) as low-cost substitutes for rare earth elements (RE) in Mg alloys to improve their formability was investigated. The results showed that some alloys exhibited dynamic strain aging (DSA) at specific testing windows, as negative strain rate sensitivity values indicated. The texture properties of homogenized and recrystallized alloys were investigated using an advanced 3D tomography method. These findings indicate that the Ca and Zn additions in Mg alloys have the potential to enhance formability through shear band formation and stacking fault energy modifications, which could facilitate the formation of RE-textured grains. |
