Originální abstrakt

The present study focuses on a vacuum induction melting and related mechanical properties of Nb-containing TiAl intermetallic cast parts. Results suggest that the wall attack of crucible can be considerably limited by either using the Y2O3 (with no SiO2-type binder) or by a suitable wall coating. Mechanical properties of the Nb-containing alloys were investigated before and after remelting in the refractory crucibles. Results show that an impairment of alloy strength may occur due to remelting.
