Site-specific atomic-scale characterisation of retained austenite in a strip cast TRIP steel
Knowledge of carbon content in retained austenite (RA) with different neighbouring phases is essential to understand the chemical stability of RA, which is useful for microstructure tuning of transformation-induced plasticity (TRIP) steels. The present study investigates different morphologies and chemical compositions of RA by correlating electron backscattering diffraction, transmission elect...
متن کاملMechanical Stabilisation of Retained Austenite in δ–TRIP Steel
Recent research suggests that extraordinary combinations of strength and ductility can be achieved in the so–called δ–TRIP steels, which contain ferrite, bainite and austenite. A part of the reason for the ductility of almost 40% elongation at a strength of some 900MPa, is believed to be the optimal stability of the austenite to plastic deformation. We demonstrate here that mechanical stabilisa...
متن کاملIdentification of Retained Austenite, Ferrite, Bainite and Martensite in the Microstructure of TRIP Steel
Transformation induced plasticity (TRIP) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. These characteristics of TRIPsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deforma...
