Abstract
Thermodynamic principles were utilized to study the stabilization of retained austenite via bainitic transformation in a 0.26C-1.52Si-1.2Mn steel. The volume fraction and stability of retained austenite are varied via thermo-mechanical processing. A plane-strain uniform ductility of 25% with a 3% flow strength of 570 MPa was achieved. The austenite stability appears to be less than the theoretical optimum, and further ductility enhancement should be achievable with increased stability via increased manganese content or decreased particle size.
