摘要

W-rich nanoclusters were directly observed using the high angle angular dark field-scanning transmission electron microscopy and mass-thickness contrast in a W-rich Ni superalloy. These nanoclusters, contributed to the strength with gamma', the solid solution and grain boundary strengthening together, were found to uniformly distribute within gamma, gamma' and phase boundaries.
