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。
This paper presents a test method for determining the inhomogeneities of submicroscopic structures (mainly lattice distortion and clump size) in the textured discrete region, and gives the quantitative distribution of texture dispersion and the distribution of merit distribution Characterization method of submicroscopic structure induced by the process of texture formation as well as the intrinsic relationship between the two are provided to provide more complete information for the study on the structural changes of the deformation process of metal materials.
