Abstract
Hardness indentations with a Vickers pyramid under a load as low as 0.1 N applied at room temperature induce amorphization in single‐crystal mullite when applied to the (001) crystallographic face. Different zones of damage were identified via TEM. Directly under the indenter, in the region of high‐compressive stress, mullite becomes amorphous. Further out toward the matrix material, there exists a region of high plastic deformation in the form of dislocation networks, radial microcracks, and bend contours. The Vickers‐induced damage is comparable to that produced by dynamic shock or intense ball milling of mullite.
