Abstract
Extension of terminal solid solubilities has been achieved by ion beam mixing in the almost completely immiscible Ag‐Ni system. Multi‐layered samples of thin deposited Ag‐Ni films of various compositions were bombarded with energetic Xe ions at temperatures from −190 to 250 °C. Supersaturated Ag‐ and Ni‐rich fcc solid solutions were obtained, as indicated by x‐ray and electron diffraction. Analyses of lattice parameters showed that the solubility range for the metastable solid solutions produced by low‐temperature bombardment was wider than for those formed at high temperature. Maximum solubilities were determined to be 4.5 at. % Ni in Ag and 16 at. % Ag in Ni if one assumes the ion‐induced fcc phases to be ideal solid solutions. The effects of implantation temperature on the formation of metastable phases are discussed.Keywords
