晶界和{100}柱状晶在硅钢生产过程中对织构的遗传和演变有关键作用,因此本文利用晶体塑性有限元方法进行立方和旋转立方取向双晶在晶界不同位向时晶体取向演变的全场模拟。模拟显示,三种晶界位向下,晶界都具有诱发晶内产生S形状形变不均匀和缓解局部形变不均匀区取向转动的特点,立方和旋转立方取向双晶在带有剪切作用的轧制条件下都显示明显的取向稳定性。GB⊥RD(表示晶界垂直于轧向)晶界位向时,旋转立方取向晶粒优先在晶界中心位置发生取向转动,而立方取向则优先在远离晶界的端部发生取向转动。GB⊥TD(表示晶界垂直于横向)的晶界位向下,其晶界阻碍作用最小,双晶内产生的取向漫散度大,织构强度较低;除绕TD转动外,也具有复杂的绕RD、ND的取向转动。GB⊥ND(表示晶界垂直于法向)的晶界位向下,取向转动与GB⊥RD时相近,但有少量取向绕ND转动。 Grain boundaries and initial{100}columnar grains play a key role in the inheritance and evolution of texture in the production of electrical steels.In this paper,the crystal plasticity finite element method was used to simulate the grain orientation evolution of cube and rotated-cube oriented bicrystals when grain boundary was set to different orientations.It was shown that the grain boundary in three grain boundary orientations demonstrated the characteristics of inducing Sshape deformation inh...
