Abstract
The influence of heat treatment on phase decomposition of Co-10 at. pct. Cu alloy was studied. The materials and phase compositions were studied by using energy dispersive spectrometry (EDS) and X-ray diffraction (XRD) techniques. XRD analysis showed that the samples contained Co, Cu, CuO and CoCu2O3 phases depending on the heat treatment regimes. Moreover it is found that the formation of dendrite Co phase render the spinodal decomposition even for deep long aging inside the miscibility gap. The crystal structural parameters were refined with FULLPROF program. 2-D computer simulation indicates that the morphology and the shape of the microstructure agree with experimental SEM micrographs for the Cu rich phase.
