Abstract
The ability to predict the stress-rupture behaviour of high temperature components is of paramount importance in both power generation and aerospace applications. Historically, the power law-based techniques such as the Larson-Miller, Manson-Haferd and Goldhoff-Sherby have typically been utilised to describe the creep behaviour of metals and alloys. These techniques, however, have some significant shortfalls such as the prediction of the long-term creep properties based on short-term measurements and the ability to describe/define full creep curves. This paper will critically review a selection of such conventional techniques in addition to some modern approaches that have recently evolved, e.g. the Hyperbolic Tangent and the Wilshire Equations Methods. These approaches will be applied to the NIMS creep data of Grade 22 Steel (2.25Cr-1Mo) whereby their capability for long-term creep prediction will be evaluated.
