Zusammenfassung
Die steigenden Anforderungen an Werkstoffe in Flugzeugtriebwerken und Verbrennungsmotoren führen zum Einsatz innovativer Hochtemperaturleichtbauwerkstoffe mit geringer Dichte und hoher spezifischer Festigkeit bei hohen Temperaturen. Dieser Werkstoffklasse gehören auch intermetallische Titanaluminide an. Dieser Artikel beschreibt die pulvermetallurgische Herstellroute dieser Werkstoffklasse. Ausgehend von der Herstellung der Legierungspulver wird eine Reihe von pulverbasierten Verarbeitungsverfahren beschrieben.
Abstract
The demand of advanced light-weight high-temperature materials with a low density and a good specific high-temperature strength for the application in advanced jet and combustion engines leads to the implementation of intermetallic titanium aluminides. The present paper describes the powder metallurgical processing route of this class of materials. Starting from powder production, a variety of powder-based production routes is presented.
