摘要：

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