摘要/Abstract

摘要：

尝试了小形变量轧制对立方织构电工钢织构形成的影响.结果表明，对含碳量较低的Fe-3.2%Si铁硅合金的初次再结晶组织施加小形变量形变和退火后，可以得到具有柱状晶结构的晶粒组织，并且得到比较集中的立方织构.柱状晶组织形成过程中伴随着∑5和∑11晶界的减少和最终消失，这种低∑重位晶界的移动主要是由于(100)取向晶粒与基体晶粒之间存在沿〈100〉或〈110〉转动36.9°或50.5°的取向关系.

Abstract:

Effects of temper rolling on the cubic texture formation in primary recrystallized electrical steel were investigated. The results show that the cubic texture with columnar structure is obtained in the Fe-3.2%Si electrical steels through temper rolling and final annealing of primary recystallized sheets. In the formation of columnar structure, ∑5 and ∑11 grain boundaries decrease and finally disappear. This is beneficial to the growth of (100)［001］ grains. The migration of those grain boundaries is due to the special misorientation of 36.9°/〈100〉and 50.5°/〈110〉between (100)［001］ grains and primaries and the beneficial annealing environment.
