An Al-Co-Cu vertical phase diagram along the 65 at% Al isopleth was constructed with the aim of growing a single decagonal quasicrystal. The decagonal quasicrystal was formed at 1000 °C via a peritectic reaction between a liquid and a cubic Al55(Co, Cu)45 phase. The decagonal quasicrystal crystallized as a primary phase for alloys with Co content less than 8.5 at% over a temperature range of 650 to 1000 °C. On the basis of the phase diagram, a single decagonal quasicrystal with a composition of Al66Co17Cu17 was grown from a starting alloy of Al65Co7.5Cu27.5 by the Bridgman method.
