Abstract
SEM with EDX and XRD analyses were used to study 21 as-cast Ni-Ru-Zr alloys. Phases were distinguished by BSE image contrast, and the primary phases were determined by their dendritic morphology, with the solidification sequences derived from the microstructure. Identification of the phases was done by EDX analyses, and they were verified by XRD. From these analyses, the solidus and liquidus surface projections were drawn. Three ternary phases were found: τ of composition ~ZrRuNi (at.%), τ at ~ZrRuNi (at.%), and τ at ~ZrRuNi (at.%). Sixteen invariant reactions were identified, and the largest liquidus surface was for ~ZrRu. [ABSTRACT FROM AUTHOR]
