Fabrication,Microstructure and Mechanical Properties of High PerformanceFerrite-bainiteSteels
Low cost ferrite and bainite(FB) steels offer the prospect of high ultimate tensile strength combined with high hole expansion ratio.The enhanced strain hardening and formabilityof FB steels were primarily associated with the fine ferrite matrix,the low residual stresses and dislocation densityand compatible deformation between both phases.This overview describes the various techniques to produce FB steels,and comparestheresulting microstructure,tensile propertiesand stretchflangeabilitywith conventional HSLA and DP steels.A new generation of ultrafine ferrite and nano-scalebainiteautomotive steelsisunder development forthe futuredemands of extremely high strength and ductilitythroughthe fabricationtechnologiesinvolvingphase transformationsandplastic deformation.
