... relationship between cooling rate, grain size, grain shape, and phase structures. It explains how the transition from liquid to solid state creates the conditions under which microsegregation occurs, and how it impacts the distribution of alloying elements, carbides, and inclusions. The link between...

... steel and came up with three different results ( Table 1.1 ). This suggests that manganese and chromium can jointly or independently form oxides; much depends upon their respective quantities in the steel as a whole, or locally due to microsegregation. If only the oxide of one element forms, it is...
