Original Abstract
The present study focuses on interaction between TiAl melt and ceramic crucibles during vacuum induction melting (VIM) of near-gamma TiAl intermetallic alloys. Two types of crucibles (based on Al2O3 and Y2O3) are considered, some with inner wall coatings. Results suggest that the wall attack can be considerably limited by either using the Y2O3 - based crucibles or the Al2O3 crucible with suitable coating.
