Abstract

The transformation behaviour of metal-enriched chalcopyrite has been studied dynamically by in situ experiments in a transmission electron microscope. In the ordering transformations which take place on cooling from the high temperature form a series of phases is described and their behaviour is related to the cooling rate. The observations indicate that the two stable forms are 1. the disordered form with space group F¯43m and 2. the low temperature tetragonal form with space group P¯42m. Alternative metastable phases are formed under conditions when the formation of the low temperature form is kinetically impeded. The significance of these observations to low temperature phase relations in the central part of the Cu-Fe-S system is discussed.
