Abstract

Microstructure refinement mechanism of Cu-7Cr in situ composite with trace Ag was investigated by scanning electron microscopy (SEM), telescope electron microscope (TEM), micro hardness tester (Hv), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD). The results show that the addition of trace Ag can promote the evolution from Cr filament to Cr particle, which results in the refinement of Cr filament with average thickness about 1 μm and Cr particle with average diameter about 0.8 μm in the Cu-7Cr-0.07Ag in situ composite. This microstructure refinement was discussed in the view of stacking fault energy and interaction intensity among the components with Cu, Cr and Ag elements. However, the addition of trace Ag exhibits the little effects on the texture and orientation of Cu-7Cr in situ composite. © 2011 Elsevier B.V.
