A series of monotonous, cyclic and creep tests is performed to elucidate the inelastic behavior of modified 9Cr-1Mo steel. The monotonous tests show that the flow stress does not depend on the strain rate at R. T. and 350℃, but does depend on it at 450℃ and 550℃. Cyclic experiments, on the other hand, reveal that the stress amplitude at lower temperatures is significantly influenced by the preceding cycles at 550℃, but is slightly affected by those at the temperatures lower than 450℃. Furthermore, the stress amplitude is not influenced by the preceding cycles at lower temperatures.
