Materials which have mixed chemical composition often exist as solid solutions at high temperature, but then either order or exsolve on cooling. Briefly discuss the thermodynamics responsible for these behaviours. [4] The potential energy, as a function of the interatomic bond length, is often represented by a parabola. Explain why this parabolic representation is often sensible, but also give an example of a material property for which the parabolic energy approximation fails.
