Yield stress rationalization of creep and creep fracture properties

For 1Cr-1Mo-0.25V steel, long-term stress-rupture lives are predicted by θ analyses of short-term creep curves, avoiding the effects of oxidation during prolonged creep exposure in air at 773-923 K. These analyses also introduce a new physically-meaningful approach as an alternative to the empirical parametric methods often adopted to represent multi-batch creep and creep fracture data.
