Temperature Dependent Surface Tension of Binary Alloys: A Simple Model
Abstract
Starting from a general expression for the surface tension γ of a binary mixture, a criterion is derived which indicates if and at which temperature the temperature derivative of the surface tension, dγ/dT, changes sign. An explicit and simple equation for this temperature is obtained by using the ideal solution model.
Abstract
Ausgehend von einem allgemeinem Ausdruck für die Oberflächenspannung γ einer binären Lösung wird ein Kriterium hergeleitet, das angibt, ob und bei welcher Temperatur die Ableitung der Oberflächenspannung nach der Temperato, dγ/dT, ihr Vorzeichen wechselt. Eine explizite und einfache Gleichung für diese Temperatur lässt sich im Rahmen des Modells der idealen Lösung angeben.
