Non-destructive test of turbine blade by SANS

Abstract Small Angle Neutron Scattering (SANS) was used to investigate, in a non-destructive way, the effect of a thermomechanical treatment on UDIMET 720 nickel superalloy, in order to study the evolution of the γ' precipitation, connected to the strengthening of the material, which suffers a very high temperature and corrosive attack.
