Figure 12
Six scanning electron microscope images arranged in two rows. The first image (a) features deformation twins with a scale bar of 20 micrometres. The second image (b) displays surface details without specific annotations, and each has a scale bar of 5 micrometres. The third (c) and fourth (d) images show complex, textured surfaces with a focus on voids, with the fourth image indicating inclusions. Images (e) and (f) continue this theme, revealing intricate surface structures at 5 micrometres each. The overall composition highlights various microscopic features, visually identified through their arrangement and annotations.(a) and (b) back-scattered electron images of heat treated at 650°C samples. Fractography of the 316L SS in (c) and (e) as-printed and (d) and (f) after heat treatment at 650°C
