Abstract
The paper presents experimental results of studying the motion of individual special tilt grain boundaries in the form of a half-loop with a facet. There is a deviation of temperature dependence of grain boundary mobility from Arrhenius dependence. This behavior is interpreted as a manifestation of grain boundary mobility hysteresis due to the faceting-defaceting phase transition. The values of the temperature of the faceting - defaceting phase transitions and the hysteresis parameters of grain boundary mobility were determined experimentally for the studied individual boundaries.
