Abstract: | Thermodynamic and kinetic properties characteristic of grain-boundary ridges on tilt \(11\bar 20]\) grain boundaries in zinc are studied experimentally. Temperatures are determined for faceting–defaceting and roughening phase transitions in grain-boundary ridges for tilt \(11\bar 20]\) grain boundaries with 35°, 57°, and 85° angles of misorientation. Mobilities and enthalpies of activation are obtained for grain-boundary ridges on the same boundaries. Parameters of inhibition are also calculated for grain-boundary ridges, according to the observed shapes of grain-boundary loops. |
