Mechanical 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...
متن کاملWeldability Investigation of Fine-grained S1100ql Steel
I. Samardžić, Faculty of Mechanical Engineering Slavonski Brod, Croatia, A. Ćorić, Bratstvo, Novi Travnik, Bosnia and Herzegovina, M. Dunđer, Department for Polytechnic, University of Rijeka, Croatia. This paper presents the results of weldability investigation on welded joints made of fine grained high-strength S1100QL steel. The investigations are performed on two welded plates by HV 10 hardn...
متن کاملSite-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 کاملThermal Stability of Retained Austenite in Bainitic Steel: an in situ study
The tempering of two–phase mixtures of bainitic ferrite and carbon–enriched retained austenite has been investigated in an effort to separate the reactions that occur at elevated temperatures from any transformation during cooling to ambient conditions. It is demonstrated using synchrotron X–radiation measurements, that the residue of austenite left at the tempering temperature partly decompose...
