采用极图分析方法，研究了一种使ｒ值显著提高的新工艺对超低碳高强度烘烤硬化钢板冷轧和退火织构沿板厚分布的影响。结果表明，它们厚向各层的分布存在一定差异，退火板的γ纤维织构极强，尤其是板心部强度明显高于表层；冷轧板的织构有利于退火板中γ纤维织构发展且心部织构作用较表层更大。 A pole figure analysis method was used to study the effects of a new process with a significantly higher r value on the thickness distribution of the cold rolled and annealed textures of ultra low carbon high strength bake hardened steel sheet. The results show that there is a certain difference in the thickness distribution of each layer. The γ-fiber texture of the annealed sheet is extremely strong, especially the strength of the sheet core is obviously higher than that of the surface layer. The texture of the cold- Development and the role of the heart more than the surface texture.
