Experimental investigation of phase equilibria in the Co–Ni–Zr ternary system

Abstract
The phase equilibria of the Co–Ni–Zr ternary system at 1 000 °C, 1 100 °C and 1 200 °C were experimentally investigated by means of back-scattered electron imaging, electron probe microanalysis and X-ray diffraction on the equilibrated ternary alloys. In this study, no ternary compound is found. The (αCo, Ni) phase region extends from the Ni-rich corner to the Co-rich corner with small solubility of Zr at three sections. At 1 000 °C and 1 100 °C, Ni5Zr, Co2Zr and Ni10Zr7 phases have large solid solution ranges, but Ni10Zr7 phase disappears at 1 200 °C. The Ni7Zr2, NiZr, Co11Zr2, Co23Zr6 and CoZr phases exhibit nearly linear compounds in the studied sections, and have large composition ranges. Additionally, some differences in phase relationship exist among the above three isothermal sections.
