以不断增长的薄板坯流程为背景,与传统流程对比分析了薄板坯流程无取向电工钢热轧晶粒组织特征;以50W800和50W1300钢为典型实例,探讨了两种流程下成品板晶粒组织、织构、磁性能及其磁时效行为的基体差异和相关原理。研究表明,薄板坯流程热轧板组织较粗大,有利于在成品板中获得粗大的晶粒和有利的织构,从而得到较低的铁损和较高的磁感。然而,薄板坯流程会造成第二相粒子的细小弥散分布与不充分析出,容易因磁时效而使磁性能恶化。 Based on the rapid development of compact strip production(CSP) processing,the characteristics of hot band grain structure produced by CSP processing were analyzed in comparison with those of conventional technology.The basic differences in grain size,texture,magnetic properties and the magnetic aging behaviors of the final sheet products produced by the two processing technologies and the corresponding principles were discussed,while steel 50W800 and 50W1300 were taken as examples.It is indicat... 

利用电子背散射衍射(EBSD)技术和场发射电子扫描显微镜(FESEM)研究了电工钢中柱状晶不同初始取向50%热压缩变形后的演变规律及其对粒子析出行为的影响。结果表明:〈100〉晶粒形变后仍为〈100〉取向,只发生绕ND∥〈100〉方向的转动,具有遗传性,粒子析出数量少。柱状晶长轴与压缩轴的偏转度增加,取向的稳定性变差,超过40°,可形成〈111〉取向,期间发生复杂的滑移系交互作用,产生较高的缺陷密度,促进粒子析出。MnS粒子主要在晶内析出,变形温度高、形变量低,粒子均无法充分析出。回复时,形变晶粒内高的储能和缺陷密度是促进粒子进一步析出的必要条件。 The evolution of initial orientations and their influence on precipitation of columnar-grained electrical steel after 50% hot compression deformation were investigated by electron backscatter diffraction technique and field emission scanning electron microscopy.The results indicate that the〈100〉orientated columnar grains remain still〈100〉after hot compression deformation,with only rotation around ND parallel to〈100〉direction,with heredity,and less precipitation.As the deviation angle between the...
