Fig. 6 Formation of chromium sulfides (gray areas, such as marked by arrow) along the surface, caused by diffusion of sulfur species along the grain boundaries of IN-690 liner. As expected, sulfide concentration decreases with depth, due to diffusion limitations. Precipitates formed along More

Fig. 16 Manganese sulfides in each specimen were manually point counted with a 100-point grid using 10 sets of 10 contiguous fields (~1 h/specimen) to obtain the data shown. The correlation between the wt% S and the manual point fraction was quite good, although the time required More
