Investigation of the behavior of steel 1.4852M in the conditions of short-term creep at 900 °C

In this study, creep curves of steel 1.4852M were obtained experimentally at a temperature of 900 °C and high values of the constant tensile strength. For each creep curve, the durations of the first and second stages of creep and the rate of creep through the first stage for different values of tim...

Description
Summary:In this study, creep curves of steel 1.4852M were obtained experimentally at a temperature of 900 °C and high values of the constant tensile strength. For each creep curve, the durations of the first and second stages of creep and the rate of creep through the first stage for different values of time were determined. The steps of developing a model to describe the obtained results are shown. This model can be used to predict the creep limit for periods exceeding many times the duration of the experiments performed.
