摘要：The current paper discusses the selection of Manson-Haferd and Larson-Miller constants on correlation results of creep rupture property in several heat-resistant steels It indicates that the change in Larson-Miller constant C(LM) has obvious effect on the predicting result of rupture life and the optimal C(LM) values will depend on materials and the optimal ranges of the values are narrow However, for Manson-Haferd constants T(a) and log t(a), they are at least phenomenally not independent variables but show a linear relationship log t(a) = 27 015-0 0267T(a) It is shown that the values of Manson-Haferd constants (T(a), log t(a)) can be selected in a wide range with deniable correlation accuracy and a set of Manson-Haferd constant (T(a) = 450, log t(a) = 15) is recommended to correlate the creep rupture data [DOI 10 1115/1 4001916]
