Figure 7. Microstructure and elemental distribution of M23C6 precipitates in the C3 Alloy: (A) STEM image showing the band-like distribution of M23C6 precipitates in the CG region; (B) STEM image displaying M23C6 precipitates in the FG region, (A1-A6) and (B1-B6) the corresponding EDS mapping of Fe, Mn, Co, Cr, Cu and C elements. STEM: Scanning transmission electron microscope; CG: coarse-grained; FG: fine-grained; EDS: energy dispersive X-ray spectroscopy.
