Abstract

The thermophysical properties of solid aluminium, magnesium and titanium alloys are extracted from literature and new measurements performed within a European concerted action (CONST 507D). In Marseille, heat capacity values for binary and ternary aluminium alloys as well as for industrial aluminium and titanium alloys are assessed between 20° and 600°C from DSC and heat content measurements using a drop method; enthalpies accompanying the precipitation and dissolution of metastable and stable phases are determined. All values are stored into the databank THERSYST together with detailed description of the materials and of the experimental conditions. Special modules enable the data selection, representation and manipulation according to the user's criteria.

Zusammenfassung

Die thermophysikalischen Eigenschaften fester Aluminium-, Magnesium- und Titanlegierungen werden aus der Literatur gesammelt und neue Messungen sind innerhalb eines europäischen Projekts (COST 507D) im Gange. In Marseille werden spezifische Wärme-kapazitäten für binäre und ternäre Aluminium- und Titanlegierungen zwischen 20° und 600°C aus dynamischer Differenzkalorimetrie und Wärmeinhaltsmessungen mit Hilfe einer Fallmethode bestimmt; daraus ergeben sich die Enthalpien, die Bildung und Auflösung metastabiler und stabiler Phasen begleiten. Alle Ergebnisse werden in die Datenbank THERSYST mit genauer Angabe der untersuchten Stoffe und der Versuchsbedingungen gespeichert. Spezielle Module erlauben die Datenauswahl, -wiedergabe und -manipulierung gemäss Verwenderkriterien.
