Ni-base single crystal (SX) superalloys are advanced materials that are used in modern land-based gas turbine blades to achieve high operation performance. However localised plastic damage of the blades caused by the mould removal process from the cast blades can result in residual stresses and subsequent recrystallisation during high temperature homogenisation heat treatment, which can be detrimental to the performance due to the inherent lack of grain boundary strengthening. The proposal therefore aims to characterise the degree and location of recrystallisation and residual strains in as manufactured turbine blades by neutron diffraction. The key objective of the experiment is to characterise the depth distribution of recrystallised microstructure and residual strain from the surface of the blade into the bulk in a SX component of complex geometry.
