摘要：
Combining the empirical relation for grain boundary (GB) segregation upon isothermal grain growth and the generalized parabolic growth law, the influence of GB energy on the grain size evolution in nanocrystalline (NC) materials is studied, while the grain-size-dependent solute excess is given using Mclean's equation. Satisfactory agreement between model prediction and experimental data from NC growth of dense NC gadolinia-doped ceria [J.L.M. Rupp, A. Infortuna, L.J. Gauckler, Acta Mater. 54 (2006) 1721-1730] has been achieved. Solute excess in GBs increases with grain growth and then tends to its saturated value, therefore, the inhibition of grain growth can be attributed to the reduction of GB energy through solute segregation, whereas, the consumed annealing time before the stop of grain growth is mainly affected by GB mobility.
