Description
Edalati and Enikeev count line defects in ceramics twisted under extreme pressure in twenty twenty-four. Ceramics are brittle since their defects barely move. High pressure torsion forces huge strain that spawns defects anyway. X ray scans measured defect density and grain size across oxide ceramics.
Densities hit near the theoretical ceiling for ceramics. Grain sizes shrank to the nanometer scale at the same time. Heat and turn counts varied the load. The counts give a firm base for defect lore in hard materials. Tuning defects could bend how ceramics behave, they suggest.
