Abstract

The mechanical behaviour of a fine-grained Cu-38.6% Zn alloy with and without 0.07% Ce was studied at 475 to 675° C. It was found that the addition of Ce lowered the flow stress by a factor of three. It was concluded that this arose from a decrease in the volume fraction of the harder alpha phase due to the reduced zinc solubility.
