| Abstract Scope |
High-strength lightweight magnesium (Mg) alloys have substantial potential for lightweighting automobiles, aircraft, and other technologies, but compared to other structural metals, our understanding of Mg alloy physical metallurgy is less mature. In particular, the widespread use of Mg alloys requires significant improvement in formability, achievable through processing to weaken the texture. Here, we study a Mg-3Zn-0.1Ca alloy during annealing while taking in-situ measurements of the evolving microstructure using near-field and far-field high-energy diffraction microscopy (nf- and ff-HEDM) and dark-field X-ray microscopy (DFXM) on ID3A at CHESS and ID06 at the ESRF. By combining the different modalities, we were able to characterize the microstructure evolution during annealing across five orders of magnitude in length scale (10 nm to 1 mm), from the subgrain morphology of individual grains to the aggregate behavior of several thousands of grains, opening a direct window to the mesoscale processes during recovery, static recrystallization, and grain growth. |
