In a previous paper, the authors demonstrated that the alloying behaviour of liquid metals can be described, in a qualitative way, by a simple cellular model. In the present paper, a quantitative analysis of heats of mixing and solution is given for liquid alloys; all parameters used in the calculations are tabulated. The values calculated from the model generally agree with available experimental data. Discrepancies between model and experiment mainly occur for systems with large negative heats of mixing and can be attributed to ordering effects in the liquid alloy. A complete list of calculated values of heats of solution of metals in liquid iron, uranium, and tin is presented. A comparison is made between the present model and existing models.
