A multi-level model for the analysis and prediction of creep and creep fracture of 2.25Cr–1Mo steel tubes
The creep and creep rupture properties of 2.25Cr–1Mo steel tubes have been analysed using the Wilshire equations. The observed behaviour patterns are then discussed in terms of the dislocation processes governing creep strain accumulation. A suitable statistical framework for analysing both the single and multi batch data available on this material is then specified. It is shown that ignoring the hierarchical nature present in many … Continue reading A multi-level model for the analysis and prediction of creep and creep fracture of 2.25Cr–1Mo steel tubes
