Prediction of tensile curves, at 673 K, of cold-worked and stress-relieved Zircaloy-4 from creep data
A constitutive creep equation, based on jog-drag and cell-formation, is used to predict tensile curves from creep data obtained in the same material. The predicted tensile curves are compared with actual stress versus plastic strain data, obtained both in cold-worked and stress-relieved specimens. F...

| Sumario: | A constitutive creep equation, based on jog-drag and cell-formation, is used to predict tensile curves from creep data obtained in the same material. The predicted tensile curves are compared with actual stress versus plastic strain data, obtained both in cold-worked and stress-relieved specimens. Finally, it is shown that the general features of the tensile curves, at low strains and low strain rates, are described by the creep model. © 1986. |
