  Experiments by casting Inconel 713 alloy were conducted to establish the possibility of influencing crystallisation by way of exploiting the effect of centrifugal and inertia forces acting on the metal in the course of silidification. It turned out that the effect of force action on the structure of castings was significant and enabled achieving a fundamental change in structure morphology. A facility was developed that enables shell mould casting in vacuum furnaces with the moulds rotating or oscillating.

  Test castings of Inconel 713LC were prepared by pouring into shell molds in vacuum furnace. The temperature was experimentally measured in the course of solidification and cooling, and the structure was evaluated in as-cast condition. Applying thermal insulation of shells, the dependence of the structure of castings on cooling rate was monitored on test castings. The solidification pattern was solved numerically, using the ProCAST simulation program.
