Abstract

In this paper, we briefly report on a detailed investigation of the morphology of voids in the Fe-40 wt.%Ni alloy using the electron holography technique. By analyzing the phase shift across the voids, we could obtain visual information on their morphology. Moreover, the obtained thickness profiles of the voids allowed us to measure quantitatively their depth and width. The obtained results are very important for further investigations of the 3-dimensional (3D) morphology of void-type defects in the material.
