采用取向分布函数分析了无取向电工钢不同再结晶退火温度下的织构变化及织构对磁感应强度和铁损的影响,并计算了无取向电工钢的磁晶各向异性能。结果表明,随着实验钢的再结晶退火温度升高,Goss织构和立方织构组分显著增强,而{111}面织构强度却减弱。较高的退火温度有利于减小织构因子,提高磁感应强度。磁晶各向异性能计算结果显示,随着再结晶退火温度升高,无取向电工钢板的磁晶各向异性能降低。 The recrystallization texture and the relationship of texture to magnetic induction intensity and core loss of a non-oriented electrical steel were investigated by orientation distribution function analysis.

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... 

通过热力学计算与模拟试验研究了含钒钛取向硅钢中氮化物析出相的析出规律与析出行为,并探讨了含钒钛元素的氮化物析出相作为薄板坯连铸连轧流程制备取向硅钢中辅助抑制剂的可行性.研究表明,在所冶炼的含钒钛取向硅钢的成分范围内,Ti N在钢液凝固末期便具备析出的热力学条件,而Al N与VN只可能在凝固后的α+γ或α+Fe3C两相区内析出.含钒钛取向硅钢中氮化物析出相以成分复杂的复合析出相为主,且随着钒钛加入量的增加,钢中抑制剂析出相总的分布密度由于含钒钛元素的氮化物析出相的增加而明显提高,使抑制剂抑制初次再结晶晶粒正常长大的能力得以加强,最终成品的磁感应强度值B8由1.857 T提升至1.898 T.同时,加入不高于0.007%的Ti与不高于0.005%的V不会影响中间脱碳退火工序的脱碳效果以及高温退火净化阶段硫、氮的脱除效果,其形成的含钒钛元素的纳米级氮化物析出相适合作为薄板坯连铸连轧流程制备取向硅钢的辅助抑制剂. The precipitation behavior of nitride precipitates in grain-oriented silicon steel containing vanadium and titanium elements produced by thin slab casting and rolling process was studied by thermodynamic calculation and simulation experiment. The feasibility of nitride precipitates containing V and Ti elements as auxiliary inhibitors was also investigated. It is found that Ti N is likely to precipitate at the final stage of solidification in the grain-oriented silicon steel,but VN and Al N can p...
