Creep measurements were made on Type 304 SS tubular specimens at 1100/sup 0/F. Various constant load multiaxial stress and strain states were introduced by a combination of pressurization and axial loading. The measurements were processed to determine the average values for temperature, pressure, and effective stress and for axial, radial, circumferential, and effective strains. Based upon these data, a creep model was evaluated, and parameters were derived for the multiaxial constant load creep tests (10 to 20 ksi) at 1100/sup 0/F as a function of stress. Microstructural characterization, including hardness measurements, grain size distribution, and cracking characteristics of the post-test specimens was made and correlated with the effective stress.
