Effect of Ag on the microstructure and properties of Cu-Fe in situ composites

Microstructure and properties of three Cu-Fe-Ag in situ composites were investigated. Distribution of Fe and Ag in the matrix was analyzed by energy dispersive X-ray spectroscopy. The presence of Ag reduced the solution of Fe in the matrix at high temperature, and the strength and conductivity of Cu-Fe-Ag composites increased at the same time. (c) 2005 Acta Materialia Inc.
