Abstract
The Knudsen method of mass-spectrometry and the integral option of the Knudsen effusion method realized under conditions of ultrahigh oilless vacuum are used in the overall temperature range from 1440 to 1916 K to investigate the evaporation of pure iron and copper and of a dilute liquid Fe–Cu solution with the copper content ranging from 0.17 to 10.1 at. %. The obtained data are used to calculate the values of standard sublimation enthalpy for Fe and Cu, as well as the partial and integral thermodynamic characteristics of liquid alloys of iron with copper. Significant positive deviations from Raoult's law are observed.
