极图数据与板材织构信息

以板材织构在线检测为应用背景，以铝板和超深冲钢板为例借助Ｘ射线测量了８组不同的极图数据，采用不同的方法计算取向分布函数，用以分析极力数据和板材织构信息的关系。研究表明，增加极图数目有利于缩小极图测量范围。同时极图测量范围缩小的方式也应与板材织构类型相关。

Pole Figure Data and Texture Informations of Metal Sheets

In the consideration of the application of texture on-line measurement to metal sheets 8 different pole figure data of an Aluminium sheet and an IF steel sheet were measured with X-ray.The orientation distribution functions were calculated differently and analysed,in order to obtain the relationship between the pole figure data and the texture informations of metal sheets.It is shown that measured area of pole figures could be reduced with increasing pole figure number,and the way how the measured area of pole figures are reduced should be related to the texture characteristics of the metal sheets.
