摘要

对无抑制剂取向硅钢不同压下率下初次再结晶退火后的显微组织、宏观织构和微观织构进行了研究。结果表明，冷轧板织构主要为α取向线{001}<110>、{112}<110>和{111}<110>织构以及γ取向线{111}<110>织构。初次再结晶退火后，α取向线织构减弱，织构主要为γ取向线{111}<112>织构。随冷轧压下率的增加，冷轧和初次再结晶织构强度增加。当压下率为88%时，初次再结晶退火后Goss织构和{111}<112>织构强度最高，最有利于发生二次再结晶。EBSD分析显示，Goss取向晶粒大多与{111}<112>取向晶粒相邻。提高冷轧压下率，Goss取向晶粒和{111}<112>取向晶粒都增加，Goss取向晶粒偏离理想取向角度减少。

Abstract

The microstructures, macrotextures and microtextures of grainoriented silicon steel without inhibitor with three different reductions of cold rolling (88%, 85% and 82%) were studied. The results indicate that the main textures are α fiber textures ({001}<110>, {112}<110> and {111}<110> texture) and γ fiber {111}<110> texture after coldrolling. Then α textures decrease dramatically while {111}<112> texture is strengthened after primary recrystallization annealing. The intensities of coldrolled textures and primary recrystallization textures increase with the increase of reduction of cold rolling. Under the reduction of cold rolling of 88%, the intensities of textures of Goss and {111}<112> are the highest after primary recrystallization annealing, which is benefit for secondary recrystallization. The orientation maps indicate that Goss grains mainly nucleate around {111}<112>orientation grains. With the increase of reduction of cold rolling, both Goss and {111}<112> oriented grains increase and the deviation from ideal Goss orientation of Goss grains decreases.
