Research on the Influence of the Complementary Phase Percentage on the Properties of Copper - Based Composites

Abstract

The article presents the method to obtain copper matrix composite with CuAl-Fe alloy particles as complementary phase. The samples were obtained by powder metallurgy methods using different percentages of complementary phase: 10, 20, 30, 40, 50% Cu-Al-Fe of average size of 100 µm. After cold pressing at a pressure of 863 MPa samples were sintered at 910 ^oC for 90 minutes. Characterization of the samples was focused on the microstructural aspects and abrasive wear behavior.
