摘 要: 研究了一种Ti-IF(Interstitial-free)钢在铁索体区热轧和退火过程中织构的变化.由于轧制过程摩擦的影响,热轧织构和退火织构在厚度方向上都有很大的差异.在钢板的表层,热轧织构的主要组分是{110}<001>,退火后表层的铁素体晶粒没有发生再结晶,该组分转变为{001}<110>;在试样的中心和1/4面,热轧织构组分主要是较弱的<111>//ND(板法向)织构和部分<110>//RD且在{001}<110>处最强;退火后中心面上的晶粒发生了完全再结晶,{001)组分转变为<111>//ND组分使<111>//ND织构成为唯一织构组分且在{111}<112>处最强. The texture characteristics in a Ti-IF steel during hot rolling in ferrite region and subsequently annealing were investigated. The results show that the texture characters at the surface were absolutely different from that at mid-section and 1/4-section due to the friction between the steels and rolls. The main components at surface before annealing were {110}(001) orientation, which transformed to {001}(110) after annealing. While at the mid-section and 1/4-section, weak (111)//ND (normal direction) texture and strong (110)//RD (rolling direction) texture focused on {001} (110) orientation was formed before annealing, but {001} (110) orientation transformed to {111}(112) transformation and only(111)//ND recrystallization texture existed after annealing.
