The Effect of Time and Temperature of Solutionizing Heat Treatment on γ′ Characterization in a Ni-Base Superalloy

Nickel-base superalloys are being used widely in the air and land-based gas turbines. The primary strengthening mechanism of these alloys is the distribution of the γ′(Ni3 (Al, Ti)) intermetallic phase. This phase is formed in two stages, including the solutionizing and aging heat treatments. In order to create a structure with the desirable properties, the solutionizing heat treatment is more important than aging. In this research,...
