Thermodynamic description of the Ga-Yb binary system

On the abilities and limitations of the linear, exponential and combined models to describe the temperature dependence of the excess Gibbs energy of solutions

“…4. This is in full agreement with Calphad assessments performed so far: there is a large number of systems known with a high-T artifact due to the linear model [10][11][12][13][14], while there is no system known so far with a low-T artifact of the exponential model among the systems studied by full Calphad assessment and properly giving the resulting data [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] (see Table 6). Based on this, the statement that the exponential model is not used as it might lead to a low-T artifact, and therefore instead a linear model is used [42] is not a wise strategy of Calphad assessment.…”
