Herstellung und Erprobung von Intermetallischen Phasen-Werkstoffen fuer hochbeanspruchte Triebwerkskomponenten. Teilvorhaben 1 Ermittlung des Eigenschaftsprofils von eutektischen IMP-Werkstoffen und Vorentwicklung der Bauteilherstellung. Abschlussbericht

Investigated was the applicability of powder injection molding and directional solidification as a manufacturing process for turbine blades made of the intermetallic alloys NiAl-(Cr, Mo) and TiAlSiNb. Powder injection molding is basically suitable for NiAl-(Cr, Mo) powder. A stator vane shirt was manufactured. Directional solidification is problematic, as extremely slow withdrawal speeds are necessary for eutectic systems. Inert shell molds are to be developed for the Ti containing alloy. Today, both the alloy and the process are not mature and optimized, yet. Successful powder injection molding is being further developed as a point-of-main-effort.
