Microsture and Properties of a Cu-Cr-Zr-Fe-Ti Alloy

Abstract:

The effect of 0.45 wt. % Fe and 0.2 wt. % Ti additions on the age hardening behavior of Cu-Cr-Zr-Zn alloys has been investigated with respect to hardness, electrical conductivity and microstructure. It was showed that the addition of Fe /Ti to Cu-Cr-Zr-Zn alloys enhance strength and hardness, but decrease the electrical conductivity, and increase the aging temperature and time for attaining peak hardness. The scanning electron microscope (SEM) and transmission electron microscopy (TEM) results showed that there are four types of phases in the alloy, Cu-matrix, Cr-rich, (Cu,Zr)-rich and (Fe,Ti)-rich phases.
