Originální abstrakt
The present study focuses on vacuum induction melting and investment casting of gamma TiAl intermetallic alloys. The attention is mainly given to a cost-effective melting process in which a primary alloy ingot is re-melted in a ceramic crucible and cast into a ceramic shell mould. The present study introduces a 1D model of the heat flow in a system composed of a TiAl intermetallic casting, a ceramic shell mould and the vacuum furnace environment. Furthermore, a 1D model of the thermal strain in the casting-mould system during cooling to room temperature is also presented. The parametric study aimed at minimizing thermal stresses provided the optimum initial mould temperatures and cooling kinetics of the system mould-TiAl castings resulted in macroscopically sound castings that were free of macrocracks.
