I'm doing a sequential refinement of a isostructural phase transition (FCC -> expanded FCC) and am having some issues at the final stage of the transformation. As the phase fraction of the initial phase is so low, refining the anisotropic strain term will force the lattice parameter to be nearly identical to that of the transformed phase. As a result, the phase fraction of the transformed phase does not go completely to 1.
Is there a way to constrain the D11 parameter of the two phases to be below a certain value to prevent this from happening? -- Nick Weadock PhD Candidate, Materials Science California Institute of Technology 1200 E California Blvd, Pasadena, CA 91125 MC 138-78 x2520
