Tensile deformation dominated by matrix dislocations at intermediate temperatures revealed using in-situ EBSD in superalloys

The traditional view holds that the dominant deformation mechanism of Ni-based single crystal superalloys at intermediate temperatures (both in tension and creep) is stacking fault shearing γ’ phases. Here, we provide direct evidence to prove that the dominant deformation mechanisms of tension and c...
