Figure 2
Schematic representation of solidification mechanisms of CF8M duplex stainless steel. The two primary phase transformations occurring during cooling are illustrated. Understanding the physical mechanisms will further help to guide the classification and segmentation methods. (a) First phase transformation from liquid to α-ferrite. (b) Common polygonal ferrite grain network resulting from full solidification. (c) Initial primary ferrite grain taken from (b). (d) Austenite (in white) starting to grow at ferrite grain boundaries. (e) Austenite growth forming laths. (f) Ferrite–austenite nested layout.
