用X射线方法测定了银-锡-铝三元系合金相图。合金含量从30wt.％Sn到纯锡,从30wt.％Al到纯铝。同时,对此三元系的富银角(<30wt.％Sn,<30wt.％Al)相图的γ相区,ζ+δ相区和β+γ+δ相区重新做了测定。室温相截面由六个单相(即α,μ,β,γ,Sn和δ)相区,八个双相(即α+μ,α+β,β+μ,β+γ,γ+Sn,β+Sn,β+δ及Sn+δ)相区,和三个三相(即α+β+μ,β+γ+Sn及β+Sn+δ)相区所构成。所有单相与三个二元系的单相一致,没有新相出现。A phase diagram of the alloys of the ternary system of silver-tin-aluminium wasconstructed on the basis of the data obtained by X-ray analysis. The phase diagram obtained consists of six single-phase regions (namely a, μ, β, γ,Sn, and δ regions), eight two-phase regions (namely α+μ,α+β,β+μ,β+γ,γ+Sn,β+Sn,β+δ and Sn+δ regions), and three three-phase regions (namely α+β+μ,β+γ+Sn and β+Sn+δ regions). No new phase was observed in these alloys of the ternary system.
