An Approach to Predict Creep Strain and Rupture Life of Heat Resistant Steels Based on ZC Parameter
The current paper proposes a so-called Zc method to evaluate creep strain and rupture life of heat resistant steels by considering the scattering distribution of experimental data, where the Zc value indicates the deviation of the fitted σ-P curves at different creep strains to the main curve. It is shown that the value of Zc increased rapidly at first and then became stable with increasing creep strain, meanwhile, the degree of deviation between experiment data and the corresponding fitted curves came to decrease. The current method provides a statistic method for predicting creep stain and rupture life and get good agreement with experiment result.
