Abstract

New “interfaces” are produced on the slip plane when a crystal with continuous composition fluctuation arising from spinodal decomposition is deformed by slip. In this work, the energy of such “interfaces” is evaluated for both modulated and mottled structures, and their effects on slip behaviour are discussed. It is concluded that the contribution of this “interfacial energy” is large enough to account for the age-hardening concomitant with spinodal decomposition.
