The in uence of intercritical deformation on the microstructure development of a TRIP steel has been investigated by the use of deformation dilatometry, X-ray diffraction, and metallography. The austenite decomposition into ferrite and bainite during cooling from the intercritical annealing and the bainitic annealing have been investigated. A very distinct effect of plastic deformation on the microstructural development has been observed. Since the plastic deformation enhances the ferrite formation during cooling, the degree of deformation can be used to control the balance between allotriomorphic ferrite and bainitic ferrite in the eventual structure. In this paper a semiquantitative phase map has been developed, showing the microstructural composition of the material as a function of the degree of plastic deformation. Using this map the in uence of the intercritical deformation on the microstructure development can be followed.MST/5834
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
