Abstract
Abstract Impurities (Cu, Sn, Cr, and Ni) have been added to a low-carbon formable strip steel to simulate the scenario of increased use of scrap during steel production. Texture evolution during annealing of the cold-rolled base steel and impurity-added steel have been investigated. The impurities were shown to suppress the development of the γ -fiber texture. Meanwhile, a higher fraction of random orientations was developed in the impurity-added steel. However, the adverse effect of impurities on the γ -fiber was mitigated during annealing at higher temperatures (650 °C to 750 °C). The correlation between texture development and microstructure heterogeneity, and the effect of impurity additions on texture development are discussed. This work provides guidelines on recycling scrap for the production of low-carbon formable steels.
