摘要: The temperature-dependent microstructure evolution and corresponding mechanical stability of retained austenite in medium-Mn transformation induced plasticity (TRIP) 0.17C-3.1Mn-1.6Al type steel obtained by thermomechanical processing was investigated using scanning electron microscopy (SEM), backscatter diffraction (EBSD), X-ray (XRD) techniques. Specimens were deformed up to rupture static tensile tests the temperature range 20–200 °C. It found that an increase deformation resulted reduced intensity TRIP effect due higher austenite. kinetics strain-induced martensitic affected carbon content (RA), its morphology, localization microstructure.
