摘要
Grain boundary grooves of pure Cu and Cu-50 at.ppm Bi bicrystals were measured by means of atomic force microscopy. An unprecedented accuracy was attained with this method. An analytical function proposed by Mullins for the grooving process was fitted to the measured groove profile. Extrapolation of this fitted function in the groove root of the profile led to accurate values of the dihedral angle.
