研究了一种Ti-IF(Interstitial-free)钢在铁素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 {00...
