| Abstract Scope |
Three solutionized Mg alloys namely, AZ31B, Mg-9%Al, and Mg-6%Al were hot rolled in a confined manner. The underlying microstructure of the samples after rolling were studied using optical and scanning electron microscopy (SEM). Mechanical behavior of these Mg alloys has also been investigated under quasi-static (strain rate ~10^-3 s^−1) and dynamic (Kolsky bar- strain rate ~10^3 s^−1) compressive loading conditions. Correlation and effect of the rolling parameters, initial texture, varying Al content, twinning-recrystallization transformation on the microstructure and mechanical properties of these Mg alloys have been studied to a greater extent. It has been found that texture randomization in these alloys has been key to improved mechanical properties. |
