Abstract

The Al—Ga—Zn ternary phase diagram presents two isobaric invariant reactions: a eutectic at 23±1°C and a metatectic at 123±1°C [1–3]. Calorimetric measurements on the two isobaric invariant reactions have been carried out. First the Tammann method has enabled us to determine the composition of their limits on five isopletic cross sections. Then, the compositions of the invariant phases have been determined.
