“…In order to coincide with our established Al-base thermodynamic database, the thermodynamic parameters from Lacaze and Sundman [16] were finally used in this work. In the case of the Cu-Mg system, there were three available thermodynamic descriptions from Coughanowr et al, [19] Zuo and Chang [20] and Zhou et al [21] Coughanowr et al [19] and Zuo and Chang [20] treated the liquid and Mg 2 Cu phases as a regular solution and a stoichiometric compound, respectively. Accordingly, Zhou et al [21] used an association model for the liquid phase and a twosublattice model to describe the Mg 2 Cu phase.…”

Based on the critical review of the available experimental phase equilibrium data for the constituent quaternary systems in the Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni quinary systems, a set of self-consistent thermodynamic parameters for these systems has been obtained using the CALPHAD approach. In combination with the constituent binary, ternary and quaternary systems, the thermodynamic database for the quinary Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni systems was developed. Comprehensive comparisons between the calculated and measured phase diagrams and invariant reactions showed that the experimental data were satisfactorily accounted for by the present thermodynamic description. The established database was used to describe the solidification behaviors of Al alloys 6063 (Al-0.39Si-0.20Fe-0.43Mg, in wt.%) and 2618 (Al-2.24Cu-1.42Mg-0.9Fe-0.9Ni, in wt.%) under Gulliver-Scheil non-equilibrium condition. The reliability of the present thermodynamic database was also verified by the good agreement between the Gulliver-Scheil calculation and experiment.

Surface Tension Measurements of 430 Stainless Steel

et al. 2014

The surface tension of 430 stainless steel was measured using an electromagnetic levitation (EML) method at temperatures of 1 707-2 000 K, under a 5 vol% H2-He atmosphere. For comparison, the surface tension was also measured using a constrained drop method; specifically the advanced sessile drop method. At 1 823 K, the surface tension of the 430 stainless steel was estimated from the electromagnetic levitation and the constrained drop methods to be 1.802 and 1.614 N/m, respectively. A subsequent analysis of oxygen content showed that the former contained ~7 ppm oxygen, whereas the latter had 60 ppm. It was therefore considered that the observed difference in measurements was the result of a contamination by oxygen. Furthermore, the EML experimental results were found to be close to the theoretically calculated values for the Fe-Cr-Si system. Consequently, for complex multi-component commercial steels such as the 430 stainless steel, the levitation method is recommended for the measurement of surface tension.

A thermodynamic analysis of the undercooled liquid and glass transition in the ternary Cu-Mg-Y system has been carried out. To this purpose, a number of experimental data on the amorphous phase and on the undercooled liquid has been considered (glass transition temperatures, specific heat). A proper modelling of the glass transition has been applied, which has been proved suitable for the description of thermodynamic properties of the liquid-amorphous phase. Calculated and experimental quantities show a good agreement. An improved description of the behaviour of the specific heat of the liquid phase on undercooling has been obtained. The present thermodynamic assessment is suitable for estimating the Glass Forming Ability in this ternary system.
