Abstract
The motion of two individual special [11\(\bar {2}\)0] tilt boundaries in the form of a half-loop with a facet is experimentally studied. The temperature dependence of the grain-boundary mobility is found to deviate from the Arrhenius law. This behavior is interpreted as the manifestation of the hysteresis of the grain-boundary mobility due to a faceting–defaceting transition. The faceting–defaceting transition temperature and the parameters of the grain-boundary mobility hysteresis are determined experimentally for the individual boundaries under study.
