Abstract

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.
