Abstract

En 中文

• In-situ observation of GB deformation response from room temperature to 950°C. • Fully considering the influence of grain size and atmospheric environment. • Multi-scale interpretation of the interaction between GBs and dislocations. • Established the plasticity fluctuation mechanism of Ni-based wrought superalloy.
