Zirconium and erbium modified Cu-Mn-Al was spray formed in an effort to increase homogeneity and damping capacity and decrease impurity levels. Although the microstructure revealed that the optimum spray forming parameters have not yet been achieved, the modified alloys showed both high damping and resistance to losing that damping over time. The elemental additions also accelerated the formation of alpha manganese at the grain boundaries during aging.
