The authors constructed the solidification diagram of alloys of the partial system Ru-ZrRu-ZrIr-Ir using data on the structure of alloys in the as-cast condition, yielded from metallographic examinations, microhardness determinations, and x-ray phase analyses together with results of an investigation of the solidus surface of the system. No ternary compounds were detected in the system. In accordance with the four three-phase regions found on the solidus surface, in the Ru-ZrRu-ZrIr-Ir system there are four invariant equilibria involving the participation of liquid, each of which is an equilibrium of the peritectic type. Their temperatures fall toward the Zr-Ru side of the composition triangle.
