Empirical relationships among creep properties of four elevated-temperature structural materials
- Oak Ridge National Laboratory (ORNL)
Elevated-temperature creep and creep-rupture data for four important structural materials are examined to determine empirical relationships among various properties. Materials used include types 304 and 316 austenitic stainless steel, ferritic 2 1/4 Cr-1 Mo steel, and nickel-base Inconel alloy 718. Results obtained allow use of rupture life and minimum creep rate data to predict time to tertiary creep, creep ductility, and creep strain-time response. Such predictions are useful since in general more data are available for rupture life and minimum creep rate than for other properties.
