A generalised Monkman-Grant relation for creep life prediction: An application to 1CrMoV rotor steel
Source abstract
Abstract
A generalised Monkman—Grant relation, which can be derived from the 4-Θ projection technique, is proposed and then used to predict creep properties at non accelerated test conditions. In this generalisation, creep rates at low strains are used to predict minimum creep rates that are then used in the Monkman-Grant relation to predict times to failure. Predictions of creep properties for 1CrMoV from this generalisation and from the 4-Θ projection technique were assessed using the mean absolute percentage error (MAPE) and mean square error (MSE)—which was further decomposed into systematic and random components.
