This paper studied the influence of Ag micro-alloying on the deformation-processed Cu-7Cr in situ composite, by a comparison of Cu-7Cr and Cu-7Cr-0.07Ag. For both alloys, the as-cast microstructure consisted of a Cu matrix and Cr dendrites: after hot and cold working the microstructure consisted of a Cu matrix containing Cr fibres elongated in the working direction. The as-cast microstructure of the Ag-containing alloy contained finer Cr dendrites. The Ag-containing in situ composite had thinner Cr fibres, higher tensile strength, higher ductility, and slightly higher conductivity. The Cu-7Cr-0.07Ag in situ composite had a good combination of properties: a tensile strength of 772 MPa and a conductivity of 77.3%IACS. (C) 2010 Elsevier By. All rights reserved.
