Abstract :
Microstructure, precipitation hardening response, and mechanical and physical properties of Cu-Cr-Ag alloy and Cu-Cr-Ag-Cealloy have been investigated using transmission electron microscopy, scanning electron microscope, optical microscope, electricalconductivity analysis, and tensile test. The influence of element Ce on the matrix refinement, impurity removal, and precipitation inthe Cu-Cr-Ag alloys has been analyzed. The experimental results show that the strength and electrical conductivity of Ce containingalloys are greater than those of Ce-free alloys after each processing step. Improvement of strength and electrical conductivity of theCu-Cr-Ag alloy by adding Ce element is attributed to removing oxygen and sulfur from as-cast alloy.
