金属锆织构的标准极图计算及分析
|
摘要
金属锆的织构会引起各向异性,获得织构信息及演变规律对锆材的加工与应用十分重要.本文利用锆的晶体结构数据、吴氏网、极图与织构的定义,建立了锆织构的任一晶面标准极图的计算方法.运用塑性变形时基本滑移面与滑移方向的演变规律揭示了纯锆金属加工方式与织构演变的内在联系,绘制了部分锆的织构标准极图.这为锆金属的加工织构演变与表征提供了理论支撑.
The texture of zirconium metal will cause anisotropy. It is very important to obtain information and evolution law of texture for the processing and application of zirconium. In this paper, by using crystal structure data of zirconium, the definition of Wulf's net, pole figure and texture, the corresponding relation between the texture of zirconium and the pole figure of a particular crystal plane is established. Based on the evolution of the basic slip plane and slip direction during plastic deformation, the intrinsic relationship between the processing mode of zirconium and the texture evolution is revealed, and the standard pole figures of some texture of zirconium metal have been drawn by theoretical calculation. This provides a theoretical support for texture evolution and characterization of zirconium metals.
