摘要: A variety of thermomechanical-processing treatments were performed on a niobium microalloyed and nonmicroalloyed Si−Mn transformation-induced plasticity steel to generate different austenite conditions (i.e., dynamic static recrystallization pancaking) prior transformation. These were, in turn, subjected transformation schedules microstructures mechanical properties. The various thermomechanical processing led structures with relatively small variation ultimate tensile strength, but elongations fracture from about 20% 60%.
