Abstract Scope Quantitative in-situ visualization of nanocrystals’ response to external stress provides a unique opportunity to understand the complex process that determines crystal deformation. We will represent a novel method that utilizes Bragg coherent diffraction imaging technique to image three-dimensional morphology and strain evolution of a silver nanocrystal under high-pressure environment sealed inside a diamond anvil cell [1]. The pressure-introduced shearing stress triggered a plastic deformation, and a deformation twin along {111} direction was observed with precisely defined twin width. This method is expected to facilitate the understanding and interoperation of the deformation mechanism of nanocrystals and provide a characterization tool to boost the rational design and tuning properties of nanomaterials.
