Abstract
A method to assess a five-component equilibrium phase diagram and to plot it on the concentration triangle is suggested. The advantages and limitations of this method are discussed. The Al–Si–Fe–Cu–Mg phase diagram, including solidification reactions, phase field distribution in the solid state and polythermal sections, is analyzed. With taking into account the change of equilibrium phase composition and phase fractions upon cooling, the aging ability of Al–Si– Fe–Cu–Mg alloys is considered.
Abstract
Eine Methode zur Analyse von Phasengleichgewichten in 5-Komponentensystemen und zur Darstellung auf dem Konzentrationsdreieck wird vorgeschlagen. Es werden die Vorteile und Einschränkungen der Methode besprochen. Das Al–Si–Fe–Cu–Mg Zustandsdiagramm wird untersucht (Erstarrungsreaktionen, Verteilung der Phasenbereiche in den Zustand- und Temperatur-Konzentrationsschnitten). Unter Berücksichtigung der sich ändernden Gleichgewichts-Phasenzusammensetzung und der Phasenmengenanteile während des Abkühlens wird die Alterungshärtungsmöglichkeit von Legierungen des Systems Al–Si– Fe–Cu–Mg behandelt
