a, b Plots of r2 vs. t of L12 precipitates in the 0Co and 15Co CCAs aged at 800, 900, and 1000 °C. c, d Arrhenius plot of the coarsening rate constant (ln(k × T)) as a function of the reciprocal aging temperature (1/T) determines the activation energy (Q) for the 0Co and 15Co CCAs based on the TIDC model. e, f Plots of r3 vs. t of L12 precipitates in the 0Co and 15Co CCAs aged at 800, 900, and 1000 °C. g, h Arrhenius plot of the coarsening rate constant (ln(k × T)) as a function of the reciprocal aging temperature (1/T) gives the activation energy (Q) for the 0Co and 15Co CCAs based on the LSW model.
