| Abstract Scope |
The role of erbium addition on texture, recrystallisation, and mechanical properties has been systematically studied in a binary Mg-Er alloy. As-cast Mg-1Er and Mg-5Er (wt. %) alloys were hot-rolled and annealed at 400 °C for different durations from 3 min to 60 min. The evolution of microstructure and texture was studied using EBSD, HRTEM and X-Ray diffraction. Recrystallisation kinetics were analysed using combined hardness measurements and the Johnson-Mehl-Avrami-Kolmogorov (JMAK) model. Additionally, tensile testing was conducted on hot-rolled and recrystallised samples. In addition, significantly influenced the propensity of twinning. It was observed that the addition of Er increased the proportion of contraction twins (CT) and double twins (DT), but decreased the proportion of extension twins (ET). Similarly, both as-rolled and recrystallised textures were studied with Er addition. |
