Abstract Scope |
Gleeble compression tests and Electron Backscatter Diffraction (EBSD) were used to study how alloying affects microstructure evolution and dynamic recrystallization (DRX) in Mg-Zn-Ca alloys. Five materials (unalloyed Mg, Mg-0.1wt%Ca, Mg-3wt%Zn, Mg-1wt%Zn-0.1wt%Ca, and ZX30: Mg-3wt%Zn-0.1wt%Ca) underwent compression at 200–350ºC and strain rates of 0.1, 0.01, and 0.001 s⁻¹. DRX activation energy was calculated using the Arrhenius equation. Unalloyed Mg exhibited the lowest activation energy, while ZX30 had the highest. EBSD Grain Orientation Spread (GOS) maps showed that ZX30 is more resistant to DRX than unalloyed Mg. The effects of processing conditions on the microstructure and texture evolution of these alloys will be discussed. |
