Abstract

Aging precipitation of Cu-0.3Cr-0.15Zr-0.05Mg alloy was investigated by energy dispersive X-ray (EDX) and transmission electronic microscopy (TEM). The results show that the fine precipitates of Cr, Cu₄ Zr and ordered CrCu₂ (Zr, Mg) are observed in the alloy aged at 470°C for 4 h. Along the grain boundary chromium is found. Properties of the aged alloy are improved due to the fine precipitates. The hardness of HV 109-108 and the electric conductivity of 79%-80% IACS are available for the alloy aged at 470°C for 4-6 h.
