Ternary ß and ? phases in the Al-Au-Cu system at 750 °C
There are many aspects of the phases and phase boundaries of the Al-Au-Cu ternary system that are still unknown. Although a 500 °C isothermal section and an 18 karat pseudobinary have been reported, many of the other constitutive relationships within the ternary are uncertain. Another unresolved iss...
