概要

• 論文の詳細を見る

• Microchemical change of a Ni-based superalloy single crystal during creep test was investigated using a position-sensitive atom probe with 3-D atomic level spatial resolution.In the vertical matrix channel of the disordered γ phase between the ordered cuboidal γ′ phases, the finely ordered γ′ phase with interconnected structure is precipitated during creep coarsening, so called rafting.Rafting progresses with the growth of the fine γ′ precipitation and the movement of the interface between the vertical channel γ and the cuboidal γ′ caused by the diffusion of constituent elements such as Al, Cr and Ni.
