铝板轧制织构的定量研究

Quantitative Investigation of Rolling Texture in Aluminium Plate

对无初始织构的工业纯铝轧制织构的研究和分析表明,取向空间、取向分布函数、正态分布模型以及取向线分析是研究织构得力而又十分简便的手段,具有许多优点。在多晶铝轧制过程中取向空间内的β线是取向最终稳定线。随变形量的提高,晶粒在β线上的聚集程度不断提高。轧制过程中主要的织构分量为C{112}<111>、S{123}<634>、B{110}<112>和G{110}<001>。它们在变形中的稳定性在此也作了分析和讨论。

The investigation on rolling texture of commercially pure aluminium without initial texturo shows, that the orientation space, orientation distribution function, Gauss model and orientation fibre analysis are more powerful and easier methods for texture research and have many advantages. During the rolling of polycrystal aluminium theβ fibre in the orientation space is the stable fibre. With increasing deformation the accumulation of grain orientations on β fibre keeps rising. The main rolling texture components are the C {112} <111>, S {123}<634>, B{110}<112> and G {110}<001>. Their stability during deformation is also analysed and discussed.
