Abstract
Industrial brasses subjected to electrochemical oxidation in tap water resulting in the selective dissolution of zinc were studied by low-te mperature internal friction (IF). In the dezincified brasses in the te mperature range of 230-300 K a complex two-component peak was observed . This peak is considered to be caused by dislocation-excessive vacanc y interaction and is of non-relaxation nature. This conclusion is base d also on the positron annihilation data obtained with dezincified bra sses. (C) 1998 Acta Metallurgica Inc.
