Abstract: |
The as-cast microstructure of the Cu-0.37Cr-0.15Zr-0.47Fe-0.25Ti was analyzed by optical microscope, scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The results show that there are three types of phases in the alloy, Cu-matrix, chromium-rich and zirconium-rich phases; coarse phases mainly consists of zirconium-rich phase. Zirconium is in form of Cu51Zr14 as massive or particle phases. Chromium is in the alloy as single phase, some chromium is as solute in the Cu51Zr14. Fe、Ti is in form of (Fe、Cr)2Ti(Zr) as massive or needle phases, which increase the hardness of the Cu-Cr-Zr alloy.
