    Microstructural and Textural Evolution of Cold Rolled Dual-Phase Steel during Annealing

    • 摘要: 通过模拟双相钢的热镀锌退火处理, 研究了钢的组织和织构演变。结果表明: 冷轧后试验钢加热到630 ℃时, 在变形铁素体晶界附近出现少量再结晶晶核, 当加热温度升高至690 ℃时, 变形组织已基本消失, 再结晶过程基本完成; 在再结晶过程中析出的细小弥散TiC、NbC相对111织构的形核具有促进作用, 阻碍了不利织构的形核, 从而使得γ织构密度增强, α取向线上的001〈110〉至112〈110〉范围内的织构密度减弱, 甚至消失; 在再结晶晶核长大阶段, TiC、NbC相对111织构的长大具有阻碍作用, 使得001〈110〉织构密度升高。

       

      Abstract: The microstructural and textural evolution of a cold rolled dual-phase steel were studied by simulating the annealing of hot dip galvanization. The results show that a small amount of recrystallization nucleus appeared nearby the grain boundaries of deformed ferrite when the tested steel was heated to 630 ℃ after the cold rolling, and the deformation microstructure disappeared and recrystallization process completed basically when temperature was above 690 ℃. The fine and dispersive TiC and NbC phases precipitated during recrytallization could promote the nucleation of 111 texture and hinder the nucleation of unfavorable texture, and thus made the density of γ texture reinforced and the textures from 001〈110〉 to 112〈110〉 range along α orientation line weaken and even disappear. TiC and NbC phases could hinder the growth of 111 texture and made the density of 001 〈110〉 texture increased during the growth progress of recrystallization nucleus.
