Small-angle Al2O3 grain boundaries achieve ultralow oxygen diffusion
Al2O3 is extensively utilized as an oxidant barrier in aeroengines and gas turbines at elevated temperatures, and small-angle grain boundaries significantly reduce its oxygen permeation. However, experimentally observing and regulating these small-angle grain boundaries poses considerable challenges...
