摘要

According to the creep date under different temperature and stress,the creep curves of Cr25Ni35Nb furnace tube material were fitted by using modified θ projection concept.The mathematical expressions of the constants θ,and the creep constitutive equation of Cr25Ni35Nb steel under arbitrary temperature and stress were established.The predicted minimum creep strain rates were also discussed.Then the creep curve at 950℃ and 18MPa was predicted.The predicted creep curve shows a good agreement with the experimental data.
