鋁板軋制織構的定量研究

Quantitative Investigation of Rolling Texture in Aluminium Plate

  • 摘要: 對無初始織構的工業純鋁軋制織構的研究和分析表明,取向空間、取向分布函數、正態分布模型以及取向線分析是研究織構得力而又十分簡便的手段,具有許多優點。在多晶鋁軋制過程中取向空間內的β線是取向最終穩定線。隨變形量的提高,晶粒在β線上的聚集程度不斷提高。軋制過程中主要的織構分量為C112<111>、S123<634>、B110<112>和G110<001>。它們在變形中的穩定性在此也作了分析和討論。

     

    Abstract: 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 the β 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>, B110<112> and G 110<001>. Their stability during deformation is also analysed and discussed.
