Fatigue‐creep interaction performance of Incoloy 825 nickel‐based superalloy at 650 °C

The fatigue‐creep interaction performance of Incoloy 825 nickel‐based superalloy at 650 °C was investigated through introducing the tensile, compressive, and tensile‐compressive strain hold time at the controlled total strain amplitude Δ ϵ t = 0.3 %∼0.7 %. The results show that the Incoloy 825 nickel‐based superalloy exhibits the cyclic hardening behavior, the cyclic hardening behavior followed by cyclic softening behavior and the cyclic...
