| Abstract Scope |
Magnesium suffers from anisotropy and strong basal texture due to its hexagonal close-packed (HCP) structure. Additionally, twinning acts as the major deformation mode during mechanical loading. Alloying with Ca and Zn has shown to weaken texture and encourage slipping as a deformation mode. In this study, the microstructural and texture evolution of Mg-(Zn, Ca) alloys during static recrystallization were quantified using in-situ heating, EBSD, and electron microscopy. The objective is to understand the influence of Ca and Zn on the twin formation mediation and texture weakening of Mg. SEM and EBSD were utilized to quantify recrystallization behavior and texture while TEM was used to understand the dislocation structure near and within various interfaces. It was determined that binary Mg-Ca and Mg-Zn retain twinning as a deformation mode and strong basal texture after static recrystallization while ternary Mg-Ca-Zn exhibit slipping and weaker texture after static recrystallization. |
