Abstract

The impact behaviour of the TiAl alloy TNBV3B produced on three different processing routes - cast, forged (with a relatively small degree of deformation) and extruded - has been studied making use of ballistic tests. The damage evolution due to centre and edge impacts on flat and airfoil-like specimens has been investigated with a focus on the influence of the microstructure. Apart from the influence of material properties, the impact location showed a strong effect on the damage evolution. The extension of impact cracks in the interior of the specimens has been studied making use of heat tinting experiments and computer tomography analyses.
