晶界偏聚元素常用于调控无取向硅钢再结晶织构，但其对织构演变的作用机制尚不清晰。本工作采用EBSD技术研究了Sb元素干预下无取向硅钢晶粒长大过程中的织构竞争。结果表明，Goss ({110}<001>)团簇的取向钉扎效应抑制了Goss晶粒长大，而毗邻晶粒通过消耗Goss团簇快速长大。晶界偏聚元素Sb通过降低Goss团簇周围{111}<112>晶粒的数量，抑制大尺寸{111}<112>晶粒的形成，削弱{111}<112>织构并强化λ织构。晶界偏聚元素Sb可通过调控织构组分的空间分布来改变晶粒长大过程中的织构竞争关系。

The recrystallization texture plays a crucial role in determining the magnetic properties of non-oriented silicon steel. Texture evolution during grain growth depends on orientation-related grain size, grain boundary characteristic distribution, and the spatial distribution of texture components. Grain boundary segregation elements can hinder nucleation and growth of recrystallization grains by reducing grain boundary mobility, and thus alter the orientation-related grain size and spatial distribution of various texture components. However, the effects of these grain boundary segregation elements on the microstructure at the completion of primary recrystallization and on subsequent grain growth behavior remain unclear. In this study, the mechanisms by which segregation elements influence texture competition in Sb-containing non-oriented silicon steel during grain growth were elucidated using EBSD. The orientation pinning effect within Goss grain clusters suppresses the growth of Goss ({110}<001>) grains, allowing adjacent grains to grow rapidly by consuming Goss grains in these clusters. The grain boundary segregation element Sb reduces {111}<112> grains around Goss clusters and impedes the formation of large-size {111}<112> grains, leading to a weakened {111}<112> texture and enhanced λ texture components. These findings demonstrate that segregation element Sb can modify texture competition during grain growth by regulating the spatial distribution of various texture components, offering a novel approach for controlling recrystallization texture.
