本文为系列研究报告《轧制板材的弹性各向异性》的第四篇。研究了宏观各向异性与微观择尤取向的关系,探讨了从试板的弹性各向异性图象推断板材织构的方法。用这个方法对六方晶系的TA2工业纯钛板进行了研究,并将推断结果与X射线方法所作的极图进行了对照。结果表明,虽然这种推断的方法只能得出关于织构的部分概念,但由于方法简便、迅速,在很多情况下将具有实用意义。 This is the fourth in a series of studies entitled “Elastic Anisotropy of Rolled Plates”. The relationship between macroscopic anisotropy and microscopic optima is studied, and the method to deduce the texture of plate from the elastic anisotropy image of the test plate is discussed. The hexagonal TA2 industrial pure titanium plate was studied by this method, and the inferred results were compared with the polar diagram made by the X-ray method. The results show that while the inferred method can only yield some of the notions of texture, its simplicity and speed make it practical in many cases.
