ABSTRACT:
Alloys are disclosed which contain Cu, Ni, Sn, and prescribed amounts of Mo, Nb, Ta, V, or Fe. A predominantly spinodal structure is developed in such alloys by a treatment which requires annealing, quenching, and aging, and which does not require cold working to develop alloy properties. The shape of articles made from such alloys may be as cast, forged, extruded, hot worked, hot pressed, or cold worked. Shaped articles are strong, ductile, and have isotropic formability.
