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.
The authors would like to thank the Portuguese Science Program PRAXIS XXI for the PhD bourse (BD / 3349 / 94). The authors would like to thank Prof. José Domingos Santos for his contributions to this work. The contribution of Mr. José Soares from CINFU in the metallographic preparation of the samples is also acknowledged.
