AbstractThe process of etching and replicating ice surfaces has been investigated. It has been shown that the process can be made selective for specific purposes by preparing the surface with a microtome and by varying the concentration of the etchant, thickness of the etchant, temperature and drying time. Replication of etch-pits in the form of whiskers was possible for both basal and non-basal dislocations, thereby directly establishing the correspondence of etch-pits to line defects. The technique was used to study the movement of non-basal dislocations under uniform and non-uniform stress fields. Grown-in defects and non-basal dislocations could be revealed by the method.
