Integrating in situ deformation and electron tomography (ET) techniques allows us to visualize the materials’ response to an applied stress with nanometer spatial resolution. The capability of structural, chemical, and morphological characterization in three-dimension real time and at sub-microscopic levels alleviates several persistent problems of two-dimensional imaging such as the projection effect and postmortem appearance. On the other hand, implementing deformation mechanism introduces additional experimental constraints that could influence the accuracy of the reconstructed volumes in a different way. To materialize quantitative and statistically relevant microstructure interpretation by time-resolved ET, we evaluated several key parameters such as angular tilt range, tilt increment, and reconstruction algorithms to characterize their influences on the accuracy of size and morphology reproducibility.

评估实现纳米级塑性变形定量电子层析成像的实验参数空间

原位整合变形和电子断层扫描（ET）技术使我们能够以纳米空间分辨率可视化材料对施加应力的响应。三维实时和亚微观水平的结构，化学和形态表征的能力缓解了二维成像的一些持久性问题，例如投影效果和验尸外观。另一方面，实施变形机制会引入其他实验约束，这些约束可能会以不同方式影响重建体积的准确性。为了通过时间分辨的ET实现定量和统计意义上的微观结构解释，我们评估了几个关键参数，例如角度倾斜范围，倾斜增量，
