摘要
以材料织构在线检测技术为应用背景,用X射线多晶面探测器测量了深冲压铝板的织构,研究了X射线二维衍射数据与晶体取向分布函数之间的关系,分析了用面探测器采集极图上不同区域数据对计算取向分布函数的影响。结果表明,面探测器可以同时采集多个极图数据,而且只采集极图上高密度值数据,忽略极图上低密度值数据,仍可准确计算取向分布函数,这为开发材料织构在线检测技术提供了理论基础。
The textures of deep drawing aluminium sheets were measured with X-ray area detector diffraction system and the relationship between the two-dimensional diffraction data and ODF was investigated. The experimental results show that the advantages of area detector are the ability to collect several incomplete pole figures simultaneously and it can only collect the high intensity data and ignore the low intensity data in pole figures, and the accuracy of ODF was basically not affected. Therefore, this new method of texture measurement could be used for developing the online texture measurement technology in industry.
