Abstract

Grain boundary motion has been investigated "in situ" in 99,9% purity V sheets in a microscope. The individual grain boundary motion has been followed by the grooves etched thermally on the surface of the sample. The velocity of individual grain boundaries has been measured and compared to the average velocity determined from the normal grain growth law. An analysis of the relation between the velocity of curved boundaries and their curvature is given. The results obtained prove that in the applied experimental circumstances the driving force of the grain boundary motion is the surface energy of the boundaries. Finally, a simple geometrical model is given for explaining the spasmodic migration of the boundaries joined to the surface, as well as the observed sudden breaking of certain grains.
