| Abstract Scope |
As the steel industry transitions to electric arc furnace (EAF) methods to achieve the decarbonization of steel production and incorporates higher levels of scrap, copper levels are expected to rise. Understanding the effects of these Cu additions is crucial for maintaining and improving steel quality in this new processing environment. Additionally, previous evaluations have shown that higher levels of copper in steel can enhance mechanical properties. This study investigates the effect of copper additions, ranging from 0.5% to 1%, on the microstructural evolution, phase transformations, and mechanical properties of high-strength steels alloyed with nickel and molybdenum. The effects of matrix constituents, base strength/hardness levels, and precipitate state were analyzed for different Cu levels during phase transformations and post-transformation treatments. The mechanisms controlling the effects of different alloying elements combined with copper during transformation, as well as the potential for precipitation strengthening, were evaluated through laboratory thermomechanical and thermal treatments |
