银-锑-锡三元系合金相圖

银—锑—锡三元系合金的室温固相截面已经用X-射线和金相两种方法测定了出来,而且每一相区的边界都用X-射线方法作了精密确定。相图中主要是由六个单相区,即α,β,γ,β′,纯Sn及纯锑单相区,和七个变相区及两个三相区所构成。没有新相出现,所有的相与银—锑二元系,银—锡二元系和锑—锡二元系所有的相完全符合。

A PHASE DIAGRAM OF THE ALLOYS OF THE TERNARY SYSTEM OF Ag-Sb-Sn

A phase diagram of the alloys of the ternary system of Ag-Sb-Sn was constructed on the basis of the data obtained by X-ray analysis and metal-lographic examinations.The phase diagram obtained consists of six single-phase regions (namely a,β,γ,β′, Sn and Sb regions), seven two-phase regions(namely a+β,β+γ,γ+β′,γ+Sn,γ+Sb,β′+Sn,β′+Sb regions) and two three-phase regions(namely γ+β′+Sn,γ+β′+Sb regions). No new phase was observed in these alloys of the ternary system.
