Aging behavior and precipitate analysis of copper-rich Cu-Fe-Mn-P alloy

► New Cu-Fe-Mn-P alloy having high strength and electrical conductivity was designed. ► The optimum property of the alloy was obtained at Fe:Mn:P molar ratio of 1:1:1. ► Precipitate phase in the aged alloy is orthorhombic FeMnP (C23 structure). ► Preferred precipitate growth direction // 〈0 1 0〉 of matrix // [0 1 0] of precipitate.
