Experimental study of the ternary Ag–Sn–Zn system through diffusion couples

The phase boundaries of the ternary Ag–Sn–Zn system have been verified using diffusion couples. Concentration and microhardness profiles of the diffusion zone have been constructed. Solid state precipitations at room temperature have been observed in the binary AgSn F.C.C. solutions as well as in th...

Description
Summary:The phase boundaries of the ternary Ag–Sn–Zn system have been verified using diffusion couples. Concentration and microhardness profiles of the diffusion zone have been constructed. Solid state precipitations at room temperature have been observed in the binary AgSn F.C.C. solutions as well as in the ternary intermediate compounds. The tin solubility in the silver is less than expected according to the pertinent binary phase diagram. Growth coefficients of the intermediate phase layers (for the ternary β, γ, ϵ phases) have been assessed.
