Analysis of the mechanical deformation arising from investment casting of directionally solidified nickel-based superalloys

Abstract:

To provide insight into the factors causing recrystallisation of nickel-based single crystal superalloys, analysis of the thermal-mechanical deformation caused by investment casting of these components is presented. Three-dimensional thermal-mechanical finite element analysis is first used to demonstrate that the reaction of the casting and mould-at least in the aerofoil section-can be approximated as one-dimensional. One-dimensional models are then built based upon static equilibrium for pla...
