Abstract
Alloy 617 is a solid-solution strengthened (SSS), γ‘- and carbide-forming Ni-based alloy. It is a promising candidate for aircraft and power plant applications at 700°C and beyond. In this work, we present a new dislocation creep model for Ni-based alloys with a low γ‘ phase fraction (<10%) and apply it to A617 in a stress range of 165 to 200 MPa at 700°C. The model is capable of predicting creep strain and rupture times based on microstructural evolution, showing good agreement to measurements and literature data.
