研究了铁素体区热轧高温卷取条件下，2种不同成分的IF钢的织构特征。结果表明，高温卷取后，普通TiIF钢发生了完全再结晶，中心面和1/4面上形成了很强的<111>∥ND再结晶织构；高强TiIF钢大部分晶粒仍处于轧制状态，只有极少部分晶粒发生了再结晶，中心面和1/4面上形成的织构组分以<110>∥RD为主，<111>∥ND再结晶织构较弱。织构分析表明，2种钢的表面织构均较弱，普通TiIF钢表面上<001>∥ND组分占优，高强TiIF钢表面上<110>∥ND组分强度最高。

The texture characteristics of two different IF steels were studied after rolling in the ferritic range and coiling at high temperature. It was found that the ordinary TiIF steel was recrystallized completely and strong <111>∥ND recrystallization texture was formed at the midsection and 1/4section. However, in the high strength IF steel, most of the grains were still in asrolled condition after coiling and <110>∥RD texture was in the ascendant at the midsection and 1/4section with very weak <111>∥ND recrystallization texture. Textures at surface in both steels were very weak and their <001>∥ND was dominant in ordinary TiIF steel and <110>∥ND in high strength TiIF steel was the strongest component.
