The solid liquid interfacial energy is found to fit well the following function of interfacial orientation in a two dimensional cross section axis of rotation is the 001 crystallographic direction. The solid is FCC. γ = γo γ4 cos (4.0 (φ − φo)) Plot the surface energy as a function of orientation for the values of γ4/γ0 = 0.05 and γ4/γ0 = 0.10. Construct the Wulff shapes for these surface energies. Let φo = 0.0 correspond to the (100) orientation
