High-temperature behaviour of Ti-Al-Nb-Ta intermetallics
Original language description
"Ti-Al intermetallics have gained significant attention as possible replacements of nickel superalloys in high-temperature applications in automotive, aerospace and energetic industry. The favourable properties of Ti-Al intermetallics are improved by alloying; keeping their low density these materials gain high strength, good structural stability, high-temperature oxidation and creep resistance. One of the common alloying elements used in this application is niobium. It improves the high-temperature properties especially the oxidation resistance. In present time the tantalum is studied as well with same or even better results. This work compares the influence of Nb and Ta on the properties of Ti-Al intermetallics. In particular, we studied the alloys of the compositions Ti-46Al, Ti-46Al-8Nb and Ti-46Al-8Ta (at. %). We evaluated the transverse strength and the hardness of as-cast samples and described their microstructure as well. Finally we inspected the high-temperature properties suc
