铝-镉-铜三元系富铜合金相图的室温固相截面已用X-射线方法测定。合金含量最高达30％(重量)铝及30％镉。 室温相截面由五个单相区α,γ_2,δ,ζ_2,η_2;十个两相区α+β,α+γ_2,β+γ_2,γ_2+δ,β+δ,δ+ζ_2,ζ_2+η,η_2+δ,η_2+β,η_2+θ及四个三相区α+β+γ_2,β++γ_2+δ,β+δ+η_2,δ+ζ_2+η_2所构成。没有发现新相。 The room temperature solid phase cross section of aluminum-cadmium-copper ternary system copper-rich alloy has been measured by X-ray method. Alloy content up to 30% by weight aluminum and 30% cadmium. The cross-sections at room temperature consist of five single-phase zones α, γ_2, δ, ζ_2 and η_2; ten two-phase zones α + β, α + γ_2, β + γ_2, γ_2 + δ, η, η_2 + δ, η_2 + β, η_2 + θ and four three-phase regions α + β + γ_2, β ++ γ_2 + δ, β + δ + η_2, δ + ζ_2 + η_2. No new phase found.
