摘要：

A modified Θ projection concept was applied to CrMoV ferritic steels to predict long-term creep curves. The concept was successful in predicting long-term curves up to rupture. Physical basis ofa constitutive equation for the concept was examined in terms of temperature dependence of its rate constant. © 1990 by ASME.
