Cu - Zr (Copper - Zirconium)

Abstract

The Cu-Zr phase diagram in [Massalski2] was redrawn from [1990Ari]. Six intermediate phases (Cu9Zr2, Cu51Zr14, Cu8Zr3, Cu10Zr7, CuZr, CuZr2) were known to exist.However, the existence of more intermediate phases was reported by [1986Kel] and [1998Bra]. [2006Wan] assessed the Cu-Zr system including these additional phases. Figure 1 shows the Cu-Zr phase diagram calculated by [2006Wan] (< 1227 °C). Cu-Zr crystal structure data given in Table 1 were taken from [1990Ari] and [Pearson3].Fig. 1Cu-Zr phase diagram[1994Zen] and [2006He] also attempted thermodynamic modeling of this system, but they were based on the older phase diagram of [1990Ari] with fewer intermediate compounds.
