Experimental investigation and thermodynamic optimization of the Y-Cu binary system

  • Published:
Journal of Phase Equilibria

Abstract

The Y-Cu binary system was experimentally investigated by DTA and XRD. The DTA results provide evidence for the possible existence of a high-temperature phase transformation in the YCu2 compound. The XRD results confirm a range of solubility for the YCu6 phase. A thermodynamic description for all the phases was obtained by taking into account all experimental data in the literature. A new phase diagram is proposed.
