Abstract The room temperature and 500℃ isothermal sections for Cu-rich (Cu+1.0 at.-％Ni)-Al-In and (Cu+1.0 at.-％Sn)-AI-In phase diagrams have been determined using X-ray diffraction method. The solubilities of Al and In in α-Cu were found to be 10.8 and 2.7 at.-％, respectively, at room temperature, and to be 19.0 and 10.5at.-％, at 500℃, while 1.0 at.-％Ni was addition. However, in the case of 1.0 at.-％Sn addition, the corresponding solubility values become 18.7, 4.9, 22.0 and 11.6 at.-％, respectively. The results show that the addition of small content nickel makes Cu-rich Al-Cu-In alloys heat-treatable.
