摘要

New steels have been developed in order tomeet the demand for higher strength (UTS>800Mpa) togetherwith excellent cold formability, based on the combination ofboth titanium precipitation hardening and dual phasemetallurgy (ferrite+martensite). Several chemicalcompositions were chosen for this study where the level ofTitanium was varied. Precipitation characterization wasperformed using Transmission Electron Microscopy coupledwith two chemical analysis techniques, namely EDS and EELSwhich is obtained through GIF (Gatan Imaging Filter). Thinfoils and carbon extraction replicas were used in order todetermine the precipitation (type, size and quantity) of thesesteels. We demonstrate that there is a good correlationbetween the evolution of mechanical properties and thenumber of small TiC precipitates.
