Failures in samples of a commercial crystallized glass subjected to intense pulsed electron‐beam irradiation resulted information of numerous full (circular) fracture mirrors. These features, resulting from simultaneous fracture initiation at internal sites, are of sizes corresponding to the range of fracture stresses found in extensive flexure tests, suggesting that the strength of this ceramic may be controlled by intrinsic (volume) defects.
