摘　　要： 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.
