Phosphor Peak

These two examples, T02_50_FeCMnPSi_PhosphorPeak_1D_TQ and T02_51_FeCMnPSi_PhosphorPeak_2D_TQ show full multicomponent diffusion with coupling to Thermo-Calc™ using industrial steel grades. The first example is one-dimensional and provides a ready benchmark against DICTRA™.

Solidification process at $t=162.0015s$ showing the ferrite/BCC_A2 (orange), austenite/FCC_A1 (white) and liquid (red) as well as the diffuse phase interfaces (blue)
