摘要：

The kinetics and morphology of the grain boundary grooving of Zn bicrystals with 16 degrees < 1010 > tilt GB by Sn(Zn) melt has been studied at 325 degrees C in equilibrium conditions in vacuum. It is shown that grooving process is interface controlled at least on the first stage. Groove walls mobility is evaluated. Changing of GB grove shape from "faceted walls" corner for annealing time < 78 h to concave "Mullins type" groove for annealing time > 78 h at the same experimental temperature was observed for the first time.
