Microstructure and Texture Evolution of Hot-Rolled Mg-3Gd Alloy during Recrystallization

An Mg-3Gd (wt.%) sample with gradient rolling strains (ε = 0–0.55) was prepared using a wedge-shaped plate after one-pass hot rolling, allowing high-throughput characterization of microstructure and texture over wide strain range within one hot-rolled plate. The evolutions were characterized as function for the as-hot-rolled annealing temperature subsequently annealed samples. deformed showed gradual change increasing strain, i.e., from deformation twins-dominant structure in low 0–0.20, to shear bands-dominant higher 0.20–0.55. recrystallization behavior during clear correlation between nucleation site microstructure. However, weak non-basal components formed almost entire range. This work demonstrates experimental strategy investigate effect various processing parameters, such temperature, on evolution microstructure, texture, mechanical properties, which could accelerate optimization parameters microstructural design.
