低碳可成型带钢中添加了杂质（铜、锡、铬和镍），以模拟钢铁生产过程中废钢使用量增加的情况。研究了冷轧基体钢和添加杂质的钢在退火过程中的织构演变。杂质被证明可以抑制γ-纤维织构的发展。同时，添加杂质的钢中出现了更高比例的随机取向。然而，在较高温度（650°C 至 750°C）退火过程中，杂质对 γ 光纤的不利影响得到了缓解。讨论了织构发展与微观结构异质性之间的相关性，以及杂质添加对织构发展的影响。这项工作为低碳可成形钢生产的废料回收提供了指南。
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 theγ-fiber texture. Meanwhile, a higher fraction of random orientations was developed in the impurity-added steel. However, the adverse effect of impurities on theγ-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.
