Abstract:

In Ni-base superalloys, the minimum creep rate is due to a small transition zone associated with a process dominated by hardening (primary creep) and recovery (tertiary creep) simultaneously. The high apparent activation energies obtained through the differential temperature creep test in Ni-base superalloy IN-X750 are attributed to changes in the substructure. When the differential change produced in temperature does not modify the substructure, the apparent activation energy by creep obtained is very approximate to the self-diffusion energy in volume of the Ni.
