Abstract
The processing technology of high Nb containing TiAl alloy was studied. The results show the mass gain during the consumable electrode arc melting is much less than that during the vacuum induction melting. The mass loss of high Nb containing TiAl alloy comes from the vacuum induction melting. The mass loss during the vacuum induction melting mainly depends on the skull size and evaporation of alloy. The fluctuation of alloy compositions during melting primarily results from the change of skull size. Al content of alloy after the vacuum induction melting is dependent on the composed effect of skull size and evaporation of alloy melt. Nb content of high Nb containing TiAl alloy gradually increases during melting. The homogenization treatment at 1200°C for 24 hours eliminates the dendrite segregation of as-cast structure.
