Projektbeschreibung
Luftfahrttaugliche additive Fertigungsverfahren für Aluminiumlegierungen
Das Ziel des EU-finanzierten Projekts AlForAMA besteht in der Entwicklung von speziell für Strukturbauteile in der Luftfahrt konzipierten bahnbrechenden hochfesten Aluminiumlegierungen sowie von auf diese Legierungen zugeschnittenen additiven Fertigungsverfahren. Die innovativen Aluminiumlegierungen werden pulvermetallurgisch hergestellt und eignen sich daher gut für das selektive Laserschmelzen. Ergebnis werden drei verschiedene maßgeschneiderte hochfeste Aluminiumlegierungen mit guten Eigenschaften für die Bearbeitung mit selektivem Laserschmelzen sein, die unter Zugabe von Si, Zr und Cu entstehen. Zu guter Letzt wird eine große Pulvercharge im industriellen Maßstab zerstäubt, und es werden zwei Bauteile für die Luftfahrt hergestellt, um die Realisierbarkeit der neuen hochfesten Aluminiumlegierungen zu demonstrieren.
Ziel
The main goal of AlForAMA project is to develop an innovative High Strength Al alloy, feasible by powder metallurgy and suitable for Selective Laser Melting (SLM), with improved weldability and increased mechanical and corrosion resistance in comparison to cast grades Al alloys currently employed in Additive Manufacturing (AM).
AlForAMA project is focused on powder bed based additive manufacturing (AM) of the innovative Al alloy. Selective Laser Melting (SLM), that utilizes a laser as a thermal energy source to melt the powder has been chosen as the preferred AM technology.
Development of the innovative aluminium alloy specifically designed for SLM will be mainly focused on two different aspects: on one hand, on tailoring the chemical composition to improve processability and/or mechanical response of well-established commercial aluminium alloys and, on the other hand, on defining the specific P/M processing of the raw powder material.
Raw materials for SLM, produced in a powder form, will be obtained by atomization process or, alternatively, by a mixing procedure of different starting powders.
A suitable heat treatment will be defined for the developed innovative Al alloy after its SLM processing. To optimize thermal treatments AlForAMA project will consider the specific microstructural characteristics that SLM generates.
SLM process development will be performed to ensure a defect free material manufacturing. A deep characterization of the new material will be carried out including mechanical, chemical and corrosion aspects. Afterwards the manufacturing process will be validated at component level.
The AlForAMA project will be developed by a well-balanced consortium that brings together 3 partners: the technical institutes LORTEK and IMDEA (Spain) and the university KU LEUVEN (Belgium).
