摘    要：本文提出了一种在织构离散区内测定亚微观结构(主要是晶格畸变和晶块尺寸)不均匀性的测试方法,给出了织构离散度和晶块尺寸择优分布离散度的定量表征方法,揭示了织构形成过程引起亚微观结构的变化规律和特征,以及两者的内在联系,为研究金属材料加工变形过程的结构变化提供了更完整的信息.

Abstract: A measuring method for uneven distribution of submicrostructure (latticestrains and crystallite size) in the fibre texture dispersed region was advanced.The quantitative expressive method of texture dispersion and dispersion of preferreddistribution of crystallite size was proposed. This paper brought to light thechange laws and characteristics of submicrostructure in the formation process of texture, and internal relation between the two. The complete information was provided for the study of structure change in deformation process of metallic materials.
