Description

Microalloying design to improve precipitate strengthening in green steels. The worldwide steel industry is currently responsible for ~8% of CO2 emissions. Decarbonising steel production is an acknowledged priority. One possibility for greener steels is much greater use of the Electric Arc Furnace (EAF), even for high quality steels requiring tight compositional control. The problem is the EAF results in higher impurity levels than traditional steel making approaches. This project aims to develop a new understanding of the effect of higher nitrogen contents (150ppm) on alloyed carbide precipitation and precipitate strengthening. We aim to design new, multi-microalloyed steels for the automotive sector that are able to tolerate, and even benefit from, the much higher nitrogen contents present in green steels..
