摘要: 介绍了基于X射线二维探测器织构的快速检测原理.以无间隙原子钢冷轧板织构的检测为例,用常规织构的检测结果作为参照标准,分析了各种X射线二维衍射条件对计算取向分布函数的影响.实验表明,用二维探测器可以同时采集多个极图的数据,合理减少样品转动,织构的检测仅需几分钟时间,且织构的检测结果与用传统X射线衍射法的一致.Abstract: The principle of rapid measurement texture based on an X-ray two-dimensional detector was described. The advantages of the two-dimensional detector were the ability to collect several incomplete pole figures simultaneously and to calculate the orientation distribution function rapidly. It was found that a complete texture in one sample can be measured in a few minutes and the accuracy of the orientation distribution function was not basically affected when the two-dimensional detector was fixed at an appropriate diffraction angle and the sample rotation was reduced reasonably. This is illustrated by an example of interstitial free steel sheets texture measurement. It is believed that the method can be used to develop a technology for online texture measurement of interstitial free steel sheets as well as other metal sheets in industry.
