Original abstract

The present paper focuses on interactions between intermetallic melts (Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy (at%)) and ceramic crucibles based on the Y2O3 refractory. The influence of a long-term exposure, during which the intermetallic melt is in contact with the crucible wall, on the structure and phase composition of the refractory is investigated. We discuss the stability of the melt – ceramic system using principles of thermodynamic equilibrium.

Czech abstract

Příspěvek je věnován studiu interakcí mezi taveninou intermetalické slitiny Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni (at %) a keramickými tavicími kelímky na bázi Y2O3. Pozornost je věnována vlivu taveniny na strukturu a fázové složení stěny keramických kelímků při tavbách s různou dobou výdrže na tavicí teplotě. Práce diskutuje stabilitu keramického systému, popisuje jednotlivá reakční rozhraní.
