摘　　要：系用极图分析的方法对一种Ｎｂ＋Ｔｉ处理的ＥＬＣ－ＢＨ钢板厚向各层冷轧和退火织构进行了研究，发现板厚向各层冷轧或退火织构的基本特征相似，但是它们的组分强度发生变化，并且这些变化之间存在着一定联系。Research on the cold rolling and annealing textures at different layers in the thickness direstion of an extra low-carbon and high strength bake-hardening sheet steel produced by added Nb and Ti has been carried out by means of the method of pole figure analysis.It is discovered that basic characteristic of cold rolling and/or annealing textures at different layers in the thickness direction of this sheet is similar,but the component strength of that varies and the definite relationship exists among these changes.
