Abstract
We illustrate how the quantitative information on interfacial thermodynamics and kinetics can be obtained from the post-mortem scanning probe microscopy studies of surface topography in the vicinity of grain boundary grooves formed during high-temperature annealing. The examples include the magnetic effect in surface diffusion in pure Fe and Fe-Pb alloys, the measurements of grain boundary energy in Ni-rich NiAl intermetallics, the effect of strong anisotropy in surface energy and diffusivity on the morphology of grain boundary grooves, and the recovery of grain boundary migration kinetics from the topography of new and abandoned grooves.
