Fig. 12

Compositions profiles of Cr and Mo during the formation and growth of the σ phase at the austenite/ferrite interface, obtained from DICTRA calculations, with aging time at 700 °C (a, b) and 800 °C (c, d), respectively. Austenite is the phase on the right side of the plot, ferrite is on the left, and σ is at the interface.
