Advances in microalloyed steels

Abstract

Microalloyed steels are one of the core alloy steels in the development of modern advanced high-strength steels. Current developments are mostly focused on the optimization of their chemical composition and process parameters to achieve the microstructures needed to fulfill the most challenging mechanical properties and performance requirements. Understanding and controlling the microstructural parameters on the basis of chemical composition strategies (i.e., proper microalloying selection) and process optimization, require a proper comprehension of the mechanisms acting during hot working and final cooling. The development of new modelling tools and powerful characterization techniques will allow the scientific community to gain fundamental knowledge and evolve towards successful products for end-users.
