New solubility data have been measured with an isothermal equilibration technique in the systems Ni-Pb and Fe-Ni-Pb. In the adopted technique, liquid lead was equilibrated in special formed quartz ampoules, either with solid nickel or an iron-nickel foil. ICP emission spectrometer and electron microprobe (EPMA) were used for chemical analysis of the phases. New solubility data together with literature data were used to obtain the thermodynamic descriptions of the systems Ni-Pb and Fe-Ni-Pb. The previous thermodynamic assessment of the system Ni-Pb has been refined, especially at its nickel rich end, below the monotectic temperature. The completed Fe-Ni-Pb ternary assessment is in agreement with the experimental observations and is valid at high temperatures, above magnetic transition temperatures.
