摘要：

Anisotropic Bi segregation, at surfaces of a Cu polycrystal saturated with Bi at 1223 K, changes the Cu equilibrium shape from a faceted spheroid displaying all orientations to an almost polyhedral shape with missing orientations. Surface cleaning, followed by annealing at similar to573 K, leads to Bi readsorption from some grain boundary sources. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
