对Cr17铁素体不锈钢冷轧钢板进行了不同温度的退火试验,利用显微组织观察、电子背散射衍射( EBSD)技术及力学性能试验探讨了退火温度对冷轧钢板的显微组织、微观织构与成形性能的关系。结果表明,随着退火温度的提高,α纤维织构变弱,取向密度逐渐降低,而γ纤维的织构强点为{111}<112>不变,取向密度逐渐增强,r值增加。当冷轧钢板在1040℃退火时,r值最大。

Annealing under different temperatures was carried out on Cr17 ferritic stainless steel cold-rolled sheet, and the relationships between annealing temperature and microstructure, texture and formability of the cold-rolled sheet were investigated by means of microstructure observation, electron back scattering diffraction ( EBSD) technology and mechanical test. The results show that with the increasing of annealing temperature, alpha fiber texture is weaker and its orientation density decreases gradually. γ fiber texture remains as{111} <112> and the orientation density increases, which lead to the increase of r value. When the cold-rolled sheet is annealed at 1040℃, r value reaches the maximum value.
