ThermoCalc simulation data for Mn35Fe5Co20Ni20Cu20 MPCA: (a) Composition profiles directly output from Scheil simulation. (b) Composition profiles at the termination of Stage II used as DICTRA inputs (dotted lines), and the profiles output from DICTRA at the termination of Stage III (solid lines). Final composition estimates from EDS performed on arc-cast material are displayed as stars. (c) Hard-sphere rendering of an example MPCA unit cell, illustrating the conversion from composition to lattice parameter (Eq. 3). (d) Lattice parameter profile matching the compositions in (a). (e) Lattice parameter profiles matching (b), including the profile at the end of Stage II (dotted line), and the profile at the end of Stage III (solid line). For simplicity, the profiles are compared at the temperature at the termination of Stage III. The dendrite (L1), interdiffusion (L2), and interdendritic (L3) regions identified correspond with the profile following Stage III.
