本文简要报导我们用X-射线衍射方法测定的铝-镉-铜三元系合金相图固相室温截面。我们的工作分两步进行:首先测定了此相图的富铜角(<30wt％~*Al及<30％Cd),然后对整个相图进行了探讨,并对前一步工作做了修正。测定的结果如图1所示。此室温截面由10个单相区(卽α,β,γ,γ_2,δ,δ′,ζ_2,η_2,θ,ε),18个双相区(卽α+β,α+γ,α+γ_2,α+δ′,γ_2+δ′,γ+β,γ+δ′,γ_2+δ,δ+ε,ε+γ_2,Cd+ε,Cd+ζ_2,Cd+θ,Cd+η_2,δ′+ε,θ_2+θ,ζ_2+η_2和θ+Al),和10个三相区(卽α+β+γ,α+γ+δ′,α+γ_2+δ′,δ′+ε+γ_2,δ+γ_2+ε,Cd+ε+δ,Cd+ζ_2+δ,Cd+ζ_2+η_2,Cd+η_2+θ和Cd+θ+Al)所构成。所有单相与三个二元系的单相
This article briefly reports the solid-phase cross-section of the Al-Cd-Cu ternary alloy phase diagram measured by X-ray diffraction. Our work is carried out in two steps: firstly, the copper rich angle (<30wt% ~ * Al and <30% Cd) of this phase diagram is determined. Then the whole phase diagram is discussed and the previous work is amended. The results shown in Figure 1. The room temperature cross section consists of 10 single-phase zones (卽α, β, γ, γ_2, δ, δ ’, ζ_2, η_2, θ, ε) γ_2, δ +, γ + δ ’, γ + β, γ + δ’, γ_2 + δ, δ + ε, ε + γ_2, Cd + ε, Cd + ’+ Ε, θ_2 + θ, ζ_2 + η_2 and θ + Al), and 10 three-phase regions (卽α + β + γ, α + γ + δ’, α + γ_2 + δ ’, δ’ + ε + γ 2, δ + γ 2 + ε, Cd + ε + δ, Cd + ζ 2 + δ, Cd + ζ 2 + η 2, Cd + η 2 + θ and Cd + θ + Al.
