Theoretical Model for Age-Hardening in Later Stages of Spinodal Decomposition

摘要

A two-dimensional composition modulation model was used to represent the later stages of spinodal decomposition of an fcc spinodal alloy. The critical resolved shear stress (CRSS) and activation energy were calculated numerically using the dislocation force-balance equation with this model. Results show that, during later stages of decomposition, CRSS and activation energy have the same results as in the earlier stages of decomposition. A consideration of three-dimensional modulation is also presented, and the results indicate that the effects are the same as in the two-dimensional case. (ERA citation 09:007867)
