Surface tension of liquid Al-Cu binary alloys.

Surface tension data of liquid Al–Cu binary alloys have been measured contactlessly using the technique of electromagnetic levitation. A digital CMOS-camera (400 fps) recorded image sequences of the oscillating liquid sample and surface tensions were determined from analysis of the frequency spectra. Measurements were performed for samples covering the entire range of composition and precise data were obtained in a broad temperature range. It was found that the surface tensions can be described as linear functions of temperature with a negative slope. Moreover, they monotonically decrease with an increase in the aluminium concentration. The observed behaviour with respect to both temperature and concentration is in agreement with thermodynamic model calculations using the subregular solution approximation

Phase diagrams and their applications to Mg alloys

This work summarizes the basics of phase diagrams and their relation to the Calphad method. It is emphasized that the benefits of quantitative prediction of phase formation of selected multicomponent alloys under equilibrium and special off-equilibrium processing conditions require the development of reliable and consistent thermodynamic descriptions forming a Calphad-type thermodynamic database. The implications of intermetallic phases in multicomponent Mg alloys are explained for ternary Mg-Ce-La/Nd alloys. An introduction to applications of this approach to phase formation in as-cast and heat treated Mg alloys is given and discussed in detail for the example of ternary Mg-Al-Zn alloys. The extension to truly multicomponent alloy systems and advanced kinetic calculations is briefly depicted
