摘　　要：采用ODF方法 ,对 3种在不同热轧终轧温度下得到的Ti+Nb处理的高强IF钢板退火织构进行了研究。结果表明 :奥氏体区终轧时 ,随着终轧温度降低 ,γ纤维织构及其 {1 1 1 }〈1 1 2〉组分有所增强 。The annealing textures of interstitial free and high strength steel sheets treated by Ti & Nb at three finishing temperatures have been examined by means of ODF respectively. Results show that when the steel is hot rolled at austenite region the intensities of γ-fibre axis texture and its ｛111｝〈112〉 constituents increase with the drop of finishing temperatures because the grains of the hot rolling and coiling microstructure are refined and the second phase particles precipitated.
