PLASTICITY OF BARIUM FLUORIDE SINGLE CRYSTALS.

Abstract

Barium fluoride single crystals exhibit considerable plasticity at 200 C. Between room temperature and 200 C, it slips in a (100) plane and in a (110) direction. Using etch pit techniques, it was observed that at 200 C fresh dislocations introduced by sprinkling with hard particles start to move at a stress level considerably lower than that indicated by compressive yielding at the same temperature. Fracture in barium fluoride was induced by microhardness indentation. It took place on both (111) and (100) planes, the (111) cleavage fracture was more common than (100) fracture. (Author)
