Effect of Anisotropy in Spinodal Decomposition
In binary systems, symmetric alloys ($c_B = 0.5$) form biconinous microstructures. Anisotropy is incorporated by modifiying the fourth rank tensor term in the Cahn-Hilliard formulation.
An off-symmetric alloy ($c_B$=0.3) will not form bicontinous microstructures (above).
