Matteo Caruso and Stéphane Godet Strain-Induced Development of Very Fine Ferrite-Cementite Structures in Eutectoid Steels Advanced Engineering Materials 14
Hot deformation of undercooled austenite induces and accelerates the γ-to-pearlite transformation. Further straining leads to the instantaneous spheroidization of the cementite and refines the ferrite grain size to 3 µm. The initial grains undergo gradual fragmentation by generation of LABs that transform progressively into HABs. This phenomenon is attributed to the presence of cementite particles and is referred to as continuous dynamic recrystallization.
