| Abstract Scope |
Mg-Ca-Zn alloys exhibit a weakened texture that is linked to increased ductility and formability. The objective of this research is to systematically quantify the deformation behavior and recrystallization mechanisms of binary Mg-2Zn(wt%) and Mg-0.5Ca(wt%) and ternary Mg-2Zn-0.5Ca(wt%) to determine the effects of the alloying elements on microstructural and texture development during static recrystallization. Coupling in situ heating with EBSD allowed for the determination of nucleation sites for recrystallized grains and their contribution to the resulting recrystallized texture. To further study the deformation modes activated within the alloys, S/TEM and dark-field x-ray microscopy (DFXM) were used to understand the dislocation structure and strain distribution near and within various interfaces (e.g. twins, grain boundaries, etc.). It was determined that the addition of Ca contributes to the suppression of twin formation and increased favorability of slip during deformation, which ultimately resulted in a significantly weakened deformation and recrystallization texture. |
