Figure 18. Calculated phase diagrams of the Fe-Cr-Al system using the CALPHAD approach: (A) isothermal section at 475 °C; (B) Fe-rich corner at 475 °C, where the solid symbols indicate α+α’ phases, the open ones designate the single α phase and the sphere symbols are the experimental data (α+α’ phases) from the FeCrAl samples irradiated at ~320 °C; (C) isothermal section at 320 °C; (D) Fe-rich corner at 320 °C together with the ones at 475, 450, 425, 400, 375, 350 and 325 °C, where the experimental data from (A) are re-labeled to adjust the phase relations at 320 °C.
