| Abstract Scope |
Residual elements including Cu and Sn present during the recycling of scrap steel via electric-arc furnace (EAF) melting can embrittle the product through hot shortness, making it susceptible to cracking in downstream processing. This work aims to evaluate the influences of alloy chemistry, processing conditions, and microstructure on hot shortness susceptibility in selected steel product classes under industrially-relevant forging, forming, and joining conditions using Gleeble® thermomechanical simulations, quench dilatometry, and hot rolling techniques. Results will be supplied to a machine learning platform to optimize data collection regimes and identify critical correlations which control the hot shortness phenomenon. We intend to use an improved understanding of hot shortness behavior to develop secondary steel compositions and production pathways with increased tolerance to residual elements, enhancing recycling efficiency and flexibility in raw material utilization. |
