Experimental liquidus points and invariant reactions in the CU-Zr system

Abstract

In the Cu-Zr system, especially between 0.25 < x(Zr) < 1, experimental liquidus points are missing and many doubts arise concerning the invariant points. In 1986, Kneller et al. [1] pointed out the existence of three phases and two eutectoid reactions which had not yet been reported. This work has been questioned by other authors [2,3]. Differential Thermal Analysis (DTA) experiments have been done in almost the whole range of compositions of the Cu-Zr system, especially where the work of Kneller et al. [1] is ambiguous; results are compared with the previous ones.
