Original Abstract
The paper deals with the physical and chemical analyses of the evaporation of aluminium from the melt, the reactions between the melt and the refractories of crucibles and ceramic moulds, and the reactions between the melt and residual gases in the vacuum furnace chamber. In present study introduces a 1D model of heat flow in the system composed of a TiAl intermetallic casting, a ceramic shell mould and the vacuum furnace environment. Furthermore, a coupled 1D model of thermal strain evolves in the casting - mould system during cooling to room temperature is also presented.
