It is verified that δ-Ni 2 Si is the most thermodynamically stable phase for precipitation strengthening among intermetallic compounds (Ni x Si y) in Cu-Ni-Si alloys . An atomic ratio of Ni/Si equivalent to 2/1 (with the mass ratio of ~ 4.2) has been suggested for Cu-Ni-Si alloys, which generates an optimization of strength and conductivity ...
