Abstract Elevated temperature exposure of 5XXX alloys causes sensitization, which leads to changes in room temperature mechanical properties and may lead to intergranular corrosion (IGC) susceptibility. The influence of sensitization and corrosion damage on the creep response of 5083-H116 at various temperatures (representative of fire damage) from 200 degrees C to 400 degrees C has been examined in this experimental study. Sensitization had a negligible effect on creep properties, while corrosion damage led to a reduction in creep rupture time and steady state creep rates. After accounting for sensitization and corrosion damage, creep rupture can be predicted based upon secondary creep/steady state creep rates.
