本文通过EBSD取向成像技术检测追踪了取向硅钢热轧、脱碳退火及二次再结晶过程中黄铜取向晶粒的形成规律.结果表明,黄铜取向的形成是热轧时Goss取向在剪切力作用下向铜型取向转动受阻而绕法向转动的结果.与Goss晶粒和{111}〈112〉取向晶粒类似,黄铜取向和{111}〈110〉取向晶粒之间存在形变与再结晶相互转化的密切关系;二次再结晶时若抑制剂钉扎控制不当,在次表层的Goss晶粒快速长入中心层之前,黄铜取向晶粒已长成大尺寸并接触样品表面,随后的Goss大晶粒就很难吞并黄铜取向晶粒.
In this paper, the formation of brass orientation grains during the hot rolling, decarburization annealing and secondary recrystallization of oriented silicon steel was tracked by EBSD orientation imaging.The results show that the orientation of brass orientation is the orientation of Goss orientation in the process of shearing As the Goss grains and {111} <112> oriented grains are similar, the deformation between the brass orientation and {111} <110> oriented grains is similar And recrystallization mutual transformation; secondary recrystallization if the inhibitor pinning improper, in the subsurface Goss grains quickly grow into the center before the brass orientation grain has grown into large size and contact with the sample surface , Followed by the Goss large grains is difficult to annex brass orientation grain.
