微区大角范围摇摆曲线的会聚束电子衍射测定

微区大角范围摇摆曲线的会聚束电子衍射测定 CBED DETERMINATION OF ROCKING CURVES WITH LARGE ANGULAR RANGE FROM MICROAREAS 王仁卉 Wang Renhui and Liu Da first-author 刘达 把中心入射束方向略不同但有一定关系的若干普通会聚束电子衍射花样适当地组合起来,可得到微区大角范围的实验摇摆曲线。本文讨论了这一方法的原理,并给出用这方法得到的奥氏体不锈钢（111）系列反射条件下微区大角范围实验摇摆曲线及其与理论计算结果的对比。 By means of appropriate combination of several conventional convergent beam electron diffraction（CBED） patterns, of which the directions of the central incident beams are a little different but have a definit relation, experimental rocking curve with large angular range may be obtained from a very small specimen region. In this paper the principle of the method is discussed. Experimental rocking curves with large angular range in the case of （111） systematic reflections for an austenitic stainless steel are given and compared with theoretically calculated ones. 摇摆曲线 会聚束电子衍射 大角度会聚束电子衍射 系列反射 Rocking curve Convergent beam electron diffraction Large angle convergent beam clectron diffraction Systematic reflection 中国科学院科学基金 1987-01-01 2021-04-01 1
