Initial microstructure (a and b) and three-dimensional behaviors of HP filling in the crack gaps in self-healed AS30P (c-f). 3D image reconstructed from 500 images from orthogonally arranged FIB-SEM images and top-view images of a healed crack close to the indenting tip in AS30P healed at 1473 K (c) and (e) for 1 h and (d) and (f) for 50 h, respectively.
