摘要：

Short-term creep data for the oxide-dispersion-strengthened 13% chromium ferritic steel, DT2203YO5, have been analysed using the theta Projection Concept. The theta methodology is shown to rationalize the complex behaviour patterns recorded when traditional power-law equations are used to describe the creep characteristics of ODS alloys. Moreover, the robust form of the theta relationships allows estimates of long-term creep and creep-fracture properties to be obtained, despite the variability of the property values recorded for alloy DT2203YO5 in tests of short duration.
