Alloy 709 is a potential material for use in structural applications for advanced nuclear reactors including sodium cooled fast reactors. It is a promising austenitic stainless steel with excellent high temperature creep strength and corrosion resistance. However, fundamental information on the creep behavior of the alloy is sparse. In this study, creep tests on Alloy 709 specimens were performed at two different temperatures (600 and 700 °C) and various applied stresses. Microstructural analyses were carried out for both as-received and crept specimens using optical microscopy, electron backscattered diffraction, and transmission electron microscopy. Fractographic analyses were conducted by scanning electron microscopy. Based on the creep data and microstructural/fractographic results, possible creep deformation and failure mechanisms are elucidated. This work is performed using funding received from the DOE-NEUP.
