Liquidus Projection and Isothermal Section of the Ag-In-Zn Ternary System

This study experimentally determines the liquidus projection and phase equilibria isothermal section at 773.2 K (500A degrees C) of the Ag-In-Zn ternary system. There are ten primary solidification phases of the Ag-In-Zn ternary system. In addition to the (Ag) (In) and (Zn) phases, there are seven binary compounds: beta-(Ag3In), zeta-(Ag3In), gamma-(Ag9In4), AgIn2, beta-(AgZn), gamma-(Ag5Zn8), and epsilon-(AgZn3). No ternary compounds were found. Among all these phases, the gamma-(Ag9In4) primary solidification phase has the largest compositional regime. Five invariant reactions, two Class I reactions, two Class II reactions, and one Class III reaction, are determined by thermal analysis in this study. The reactions with the lowest and highest reaction temperatures are Liquid = (In) + AgIn2 + gamma-(Ag5Zn8) at 413.5 K (140.3A degrees C) and Liquid + (Ag) + beta-(AgZn) = zeta-(Ag3In) at 964.9 K (691.7A degrees C), respectively. In the isothermal section at 773.2 K, there are six tie-triangles: (Ag) + zeta-(Ag3In) + beta-(AgZn), zeta-(Ag3In) + gamma-(Ag9In4) + beta-(AgZn), zeta-(Ag3In) + gamma-(Ag9In4) + Liquid, gamma-(Ag9In4) + beta-(AgZn) + Liquid, beta-(AgZn) + gamma -(Ag5Zn8) + Liquid, and gamma-(Ag5Zn8) + epsilon-(AgZn3) + Liquid.
