摘要：

Interference microscopy has been used to measure the surface profile of a thermal pit at the intersection of three grain boundaries on the surface of an annealed nickel foil. The experimentally obtained profile is compared with the predictions of a recently developed model of thermal pitting at grain boundary vertices by surface diffusion. This comparison indicates reasonable agreement between experimental observations and theoretical predictions.
