Fig. 1: Microstructural characterization of solution-treated and aged samples.

EBSD phase maps and XRD patterns of the microstructure of the solution-treated sample (a, b) and samples aged at 700 °C (c, d) and 800 °C (e, f) for 500 h. In the EBSD phase map, ferrite is shown in green, austenite in red, σ phase in light blue and Cr2N in dark blue.
