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...

对3层高硅电工钢复合板铸坯进行热轧及温轧变形加工后,采用正火、退火两种热处理方式处理,并观察轧制过程中产生的裂纹,研究不同状态下复合板的磁性能。对不同状态下的试样进行扩散退火处理,研究复合板中裂纹变化及其对磁性能的影响。结果表明:不同热处理工艺下合金内部的裂纹尺寸差异明显,裂纹尺寸对复合板的磁性能影响显著,相对于深裂纹,其他因素的影响较小;温轧变形加工后,复合板内层出现有序组织,但该有序组织在合金存在深裂纹的前提下并不能从本质上提高合金的磁性能;扩散退火工艺可以消除复合板内部的浅裂纹及微裂纹,但不能消除尺寸较大的裂纹,故而不能显著提高存在深裂纹的复合板的磁性能。 After hot rolling and warm rolling deformation processing of casting billet for three-layer high silicon electrical steel composite plate, it was normalized and annealed for heat treatment.
