The advancement and transition of computational materials models requires corresponding developments in experimental methods to provide new phenomenological insights as well as quantification of model performance. In this article, we explore the natural links between crystal plasticity modeling and a suite of high-energy X-ray diffraction experimental techniques referred to as high-energy diffraction microscopy (HEDM). HEDM methods provide information such as the elastic strain state of individual grains and the distribution of crystallographic orientations. As a non-destructive characterization method, pairing HEDM with in situ mechanical testing enables tracking of material state evolution through quantitative measurements that may be directly compared to a simulation. We highlight some recent successes in this area and provide suggestions for future research.

计算材料模型的发展和转变需要实验方法的相应发展，以提供新的现象学见解以及模型性能的量化。在本文中，我们探索了晶体可塑性建模与一套称为高能衍射显微镜（HEDM）的高能X射线衍射实验技术之间的自然联系。HEDM方法可提供信息，例如单个晶粒的弹性应变状态以及晶体学取向的分布。作为非破坏性表征方法，将HEDM与原位配对机械测试可以通过定量测量跟踪材料状态的演变，这些测量可以直接与模拟进行比较。我们重点介绍了该领域的一些最新成就，并为将来的研究提供了建议。
