• Natural frequency method (NFM)-a novel approach for the measurement of creep damage was proposed in this paper. The techniques with instrument configuration, sample cutting and experimental procedure were described in detail. The application of the approach has been made on material 25Cr20Ni that was widely used for furnace tubes. The measured results of creep damage show good agreement with theoretical predictions. The critical damage value ω_<cr> of 25Cr20Ni has been also obtained by the proposed approach. Compared with current density method and load-on and load-off method, NFM has many advantages, such as higher accuracy, simpler apparatus and better repeatability. On the basis above, an efficient approach was given for life prediction and extension of high temperature components.
