| 内容記述 | The creep rate of ferritic iron-chromium alloys with chromium contents of 15, 20 and 25 wt%, respectively, has been measured as a function of temperature and applied stress in the temperature range from 600 to 800℃. The results obtained are summarized as follows : (1) The activation energy for steady-state creep becomes maximum near the Curie point. This anomaly shows that the creep rate is closely related to self-diffusion of either one of the alloying elements or of both. (2) The measured steady-state creep rate is proportional to (stress)^n. The value of the stress exponent, n, ranges from 4.6 to 5.0, and is found to be independent of the concentration of chromium and temperature within the experimental errors. (3) The stress dependence of the activation energy for steady-state creep shows that the rate above the applied stress of 2.5 kg/mm^2 and below the Curie point is controlled mainly by the nonconservative motion of jogs which pin the screw dislocations. | |||||||||
