Diffraction data were collected using synchrotron X-ray scattering (sXRD) and electron back-scattered diffraction (EBSD) during tensile-compressive deformation of Mg alloy AZ31B dogbone samples. The onset and evolution of twinning and detwinning were monitored based on intensity changes in sXRD 2D scattering patterns (which also provided average elastic strain values through the calculation of orientation-specific lattice spacing changes), and EBSD, that revealed the micro-scale grain morphology changes. The observations were interpreted and analysed with the help of crystal plasticity finite element modelling (CP-FEM), as reported in the published article (https://doi.org/10.1016/j.ijplas.2019.02.018).
在镁合金AZ31B狗骨形样品的拉伸-压缩变形过程中，使用同步加速器X射线散射（sXRD）和电子背散射衍射（EBSD）收集衍射数据。基于sXRD二维散射图案中的强度变化（通过计算特定取向的晶格间距变化也可提供平均弹性应变值）以及揭示微观尺度晶粒形态变化的EBSD，监测孪生和去孪生的起始及演变过程。如已发表文章（https://doi.org/10.1016/j.ijplas.2019.02.018）所报道，借助晶体塑性有限元模拟（CP-FEM）对这些观察结果进行了解释和分析。
