Silver - Aluminium - Zinc

Introduction

The Ag-rich portion of the system has been studied by [30Uen]. Since the author interpreted the thermal analysis and metallographic results without regard to the inevitable existence of three- and four-phase equilibria, only a proportion of the given data are applicable to the liquidus surface. The part below 50 mass% Ag was investigated accurately by [40Geb] using thermal analysis, X-ray and metallographical techniques. Although the phase relations were analyzed at 350°C, only vertical sections at a certain Zn concentration are given. [84Pop] studied the precipitation phenomena with X-ray, electron diffraction and electron microscopy. The precipitated phase and its lattice parameter of 5 alloys in the Al-corner are determined.
