Kinetic Model of Isothermal Bainitic Transformation of Low Carbon Steels under Ausforming Conditions
Alloys, 2022 Carbide-free bainitic steels show attractive mechanical properties but are difficult to process because of the sluggish phase transformation kinetics. A macroscopic model based on the classical nucleation theory in conjunction with the modified Koistinen–

Effect of Ausforming on the Macro- and Micro-texture of Bainitic Microstructures [PDF]
Metallurgical and Materials Transactions. A, 2021 The reason why variant selection phenomena occur in ausforming treatments is still not known. For that reason, in this work, the effect of compressive deformation on the macro and micro-texture of a bainitic microstructure was analyzed in a medium-carbon
