Herein,the evolution of long-period stacking ordered(LPSO)phases in the as-cast Mg-6Gd-1Zn-0.6Zr(wt.%)alloy are investigated via transmission electron microscopy(TEM)and atom probe tomography(APT).The TEM results reveal that two types of LPSO phase(a bulky interdendritic phase and a plate-like matrix LPSO phase)are formed in the as-cast *** of the LPSO phases are confirmed to be of the 14H type,with a smaller proportion being of the 18r ***,the APT results reveal that the composition of the interdendritic LPSO phase is closer to that of the ideal 14H phase compared to the matrix LPSO phase,and both the interdendritic and matrix LPSO phases exhibit a Gd/Zn ratio of 2.5,thereby indicating a deficient Zn content compared to the ideal 14H phase(i.e.,1.3).In addition,the influence of the LPSO phases on the deformation behavior is investigated at different compressive plastic strains using electron backscatter diffraction(EBSD)analysis to reveal twinning and slip behavior during *** results indicate that the LPSO phase induces additional work hardening in the late stage of deformation via the suppression of{1011}compressive twinning and the activation of non-basal slip systems.

Controlling the concentration of defects in reduced graphene oxide （rgo） to tailor its electrical and physicochemical properties has remained a significant challenge. We report that extent of microwave （MW）-driven annealing of rgo is influenced significantly by its bulk density, which allows us to vary its defect density and crystallite size over wide ranges by controlling this parameter. Extent of anneal- ing was investigated by multiple techniques including raman and X-ray photoelectron spectroscopies, and electrical conductivity measurements. Improved corrosion resistance of rgos upon annealing was ex- amined by cyclic voltammetry in H_2SO_4 electrolyte and temperature-programmed oxidation of rgo. Our results indicate that a low bulk density of rgo facilitates defect annealing, yielding high-quality carbon with 99.3 wt% purity, oxidative resistance as high as graphite powder, and an electrical conductivity of 36,000 S m-1 in the compressed powder form. These results demonstrate a prospective synthesis route for tailor-made nanocarbons from rgo through MW-driven annealing.
