Originální abstrakt

The paper deals with physical and chemical analyses of the evaporation of aluminium from a TiAl melt, with reactions between the melt and the refractories of crucibles, and with reactions between the melt and residual gases in the vacuum furnace chamber. 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.
