摘要: Abstract Hillert showed an elegant way to obtain the equilibrium composition of interfaces (including grain boundaries) and interfacial energy for binary solutions using his “parallel tangent construction”. However, this method is correct only equal sizes atoms components. A corrected equation derived here from two fundamental equations Gibbs. Our resulting non-parallel construction less elegant, but more compared parallel Hillert. also extended multi-component solid solutions. equivalent Butler equations, without a need introduce partial energies.
