Abstract

A γ′ strengthened Co-base superalloy with enhanced high temperature properties has been newly developed and the microstructure is mainly composed of a γ⁄γ′ (fcc/L12) structure. The cuboidal γ′ phase is formed with a bimodal distribution and is suggested to play the role of precipitation hardening.
