Abstract
Nitriding is widely used for surface hardening of steels. Presented here is a cross-section of nitrided steel obtained from a steel industry. Through channeling BSE imaging, nitrided case is revealed clearly at the surface of steel and exhibits a darker contrast. It is demonstrated clearly that nitriding proceeds preferentially along the grain boundaries, as indicated by the arrows (Figs. E31.1, E31.2b). For local regions where pearlite structure is evident, it is also shown that nitriding proceeds even along the cementite which appears dark and have lineal feature, as shown by the arrows (Fig. E31.2a)
