Coherent interfacial energy and composition profiles in ternary FCC systems by a discrete lattice plane analysis

Microstructure and strength modelling of Al–Cu–Mg alloys during non-isothermal treatments: Part 2 – Welds

“…This interfacial entropy would cause a decrease of the effective interfacial energy. 42,43 A further issue in relation to the KW model is that it applies a drastic approximation in describing the threedimensional distribution of solute around any precipitate by just two parameters: the local concentration in the matrix right next to the precipitate and the average concentration. This approximation implicitly makes a number of assumptions, one of which is that the concentration profile c(r,t) in the section of matrix nearest to one particular precipitate is monotonically decreasing or increasing with r. However, for fast changes in temperature, this assumption can break down, and c(r,t) in the matrix nearest to one particular precipitate may have multiple minima and maxima.…”
