(a) correlation between nanoscale segment detrapping events and spatial deviations from chemical disorder (Atoms are colored according to the coarse-grained α

_{C o C r}^{1}

; darker color means stronger Co-Cr short-range-order (more negative α

_{C o C r}^{1}

); the dislocation is outlined in blue and its swept area are outlined in green)
(b) LCO-induced strengthening (The average activation barriers, activation volume as well as activation stress associated with the nanoscale segment detrapping process; RSS is for random solid solution and T_a represents the temperature for Monte Carlo simulation)
