Morphologies of Widmanstätten Structures and Mechanism Formation in Steels
This paper presents a research concerning the equilibrium of ferrite and secondary cementite and Widmanstätten structure formation, resulting in precise conditions. If all researchers agree with the mechanisms of ferrite and massive cementite formation in steels, the Widmanstätten structure formation is rather disputable and new data in the area of massive transformation might account for the formation of Widmanstätten structures in the low carbon steels. For the massive phase and Widmanstätten structures, the mathematic relations regarding the rate of growth are presented.
