摘要

本文借鉴常规低温渗氮钢制备工艺,采用轧制法结合低温渗氮追加抑制剂的方法制备取向高硅钢。采用EBSD取向成像技术以及EDS技术观察了取向高硅钢轧制过程中织构演变及第二相粒子析出行为,从而分析取向高硅钢二次再结晶行为异常原因。研究结果表明,高硅钢轧制过程中"组织与织构"遗传性较强。热轧板沿厚度方向上组织与织构的不均匀性,延续到后续轧制工艺中,造成初次再结晶晶粒尺寸不均匀,影响二次再结晶的进行。原始板材厚度小,总形变量小,温轧的反复退火,较小的冷轧压下量导致初次再结晶织构不理想,{111}〈112〉织构不够锋锐,Goss晶粒取向不够准确。在高温退火阶段,第二相粒子分布的不均匀性,使得次表层晶粒钉扎过强而中心层晶粒钉扎较弱,中心层晶粒吞并次表层Goss晶粒长大,导致二次再结晶组织发生异常。
This study is in reference to conventional low temperature nitriding process,adopting rolling method combined with low temperature nitriding to manufacture grain oriented high-silicon steel.Electron back-scattering diffraction(EBSD) analysis technique and EDS technique were used to reveal the texture evolution and second-phase particles precipitated during rolling process to analyze deteriorating secondary recrystallization of grain oriented high-silicon steel.The study showed that the heredity of structure and texture is strong in high silicon steel during rolling process.Inhomogeneity of structure and texture in hot rolled sample along the thickness direction extends to subsequent rolling process,which make primary recrystallization grains size uneven,influencing the occurrence of secondary recrystallization.The {111} <112> texture has a lower intensity after primary recrystallization and the Goss-oriented grain is not accurate due to the small original sheet thickness,total deformation and repeated annealing during warm rolling.During high temperature annealing,inhomogeneity of second phase particles distribution lead to strong inhibitors in subsurface and weak inhibitors in center layer.The grains in center layer grew up by merging Goss grain in subsurface,which leads to deteriorated secondary recrystallization.
