• 論文の詳細を見る

• The creep curves of wet-hydrogen-treated polycrystalline irons were obtained in the range of temperature 350°-77°K. A rapid load testing machine, which has the same principle as Clark-Wood machine, was used for the creep tests. Delay times were observed in the range of the time 10^<-2>-10^3 seconds. Observed results is analysed with the use of the strain rate equation, ε^^・=bnv. It is shown that the inverse of the delay time is approximately proportional to dislocation velocity. It is discussed that the delay time in low carbon steel is also closely related to the properties of moving dislocations.
