Microstructure and properties of a Cu-Cr-Zr alloy
TL;DR: In this paper, the precipitation in an alloy having a nominal composition of Cu 1 wt% Cr 0.1 wt % Zr has been shown to take place through the formation of a metastable ordered fcc phase, and the improvement in fatigue resistance due to the addition of zirconium has been ascribed to lowering of the stacking fault energy of the alloy.
