| Abstract Scope |
Residual elements from scrap steel recycling, most notably copper, are known to result in processing challenges such as hot cracking during thermomechanical processing. As the concentration of copper and other residuals in steel scrap streams increases, Electric Arc Furnace (EAF) scrap recycling heats commonly use pig iron to dilute residuals below current limits. Our work focuses on establishing residual element tolerant compositions and concomitant processing windows that can simultaneously mitigate issues from residuals during thermomechanical processing. Alloy chemistry, microstructure, and hot forging conditions are being analyzed to establish a hot cracking mitigation model. The effects of residuals on transformation behavior upon cooling from common hardening and joining processes is also of interest. We aim to increase residual element tolerance in secondary steels, yielding a more sustainable manufacturing pathway with a substantially smaller carbon footprint. |
