Thermodynamic properties for Ar-Al, Ar-Cu and Ar-Fe mixtures from 0.3 kK up to 4 kK for 1 atm

Abstract

Abstract The subject of the article is the thermodynamic properties (tdp) of mixtures of Ar-Al, Ar-Cu and Ar-Fe in thermodynamic equilibrium state. In current published works the metals in the mixture are assumed to be in the gaseous state. In the present work, the metals are at a temperature of 0.3 kK crystalline substances which with increasing temperature change to liquid and gaseous substances. The proportion of metal in the mixture is in the interval from 0 to 100 mass%. The calculation results are presented in the figures and in detailed tables in the TDPtables.txt in the Supplementary material. The physical model of the calculation of tdp is a simplification of reality. The results of tdp calculation are affected not only by this simplification but also by the inaccuracy of input data. Attention is devoted to these simplifications and inaccuracies. The discontinuities of thermodynamic properties caused by phase transitions are analysed.
