Abstract

Abstract : The solid-state phase equilibria of the copper (Cu)–dysprosium (Dy)–titanium (Ti) ternary system at 973 K has been experimentally investigated. The existence of nine binary compounds, Cu4 Ti, Cu3 Ti2, Cu4 Ti3, CuTi, CuTi2, CuTi3, CuDy, Cu2 Dy, and Cu5 Dy was confirmed. The controversial phase of CuTi3 was found in this work. The temperature range of Cu7 Dy was determined to be from 1112 to 1183 K. The phase relations at 973 K are governed by ten ternary phase regions, 21 binary phase regions, and 12 single-phase regions. The solid solubility of Cu in Dy is undetectable. None of the other phase in this system reveals a remarkable homogeneity range at 973 K.
