Original abstract
The present study reports on the investment casting of near-gamma TiAl intermetallics. The attention is paid mainly to the minimization of thermal mismatch strains generated in an intermetallic cast and a ceramic shell mould during cooling to room temperature. The mismatch strains stem from different thermal expansion coefficients of near-gamma TiAl alloy and the mould ceramics. A numerical modeling and optimization helped to spot those process parameters that are most influential with respect to the stress state in the cast-mould system. The optimization based on a sequential technique and on a modified random search routine yielded a processing window in which sound casts can be fabricated.
