Web25 Oct 2024 · Modelling of tertiary creep in single-crystal superalloys – operative over the majority of the temperature/stress regime of relevance – is assessed. Traditional, empirical approaches are useful for the prediction of component life; a modern trend is for more physically faithful models which account for microstructure and alloy composition. WebThis is often called the Monkman-Grant (1956) relationship [9] in which the product of the minimum creep rate and rupture time is found to be constant for a given mechanism. …
