Abstract
Dislocations formed during the growth and deformation of BeO single crystals were studied with x-ray and electron microscopy. The stresses for slip on the systems (0001) 〈112̄0〉, {101̄0} [0001], {101̄0} 〈112̄0〉, and {112̄2} 〈112̄3〉 are approximately 3.5×108, 1.1×109, 4.9×108, and >2.5×109 dyn/cm2, respectively, at 1000°C. Slip directions in deformed specimens were shown with x-ray microscopy. Defects in the specimens were shown to interfere with slip. Dislocation pinning and elastic interactions were observed in electron micrographs. These observations are correlated with theory.This publication has 11 references indexed in Scilit:
