| Popis: | Effect of loading rate on cleavage failure probability for ferritic/martensitic steels using Weibull stress analysis is studied. Calibration of Weibull slope for two grades of fusion reactor blanket steels namely, Indian Reduced Activation Ferritic/Martensitic Steel referred as In-RAFMS, F 82H and a non fusion grade modified 9Cr-1Mo steel (P91) are performed for the first time. The calibrated values of Weibull slope is used to predict the fracture behaviour of In-RAFMS at three different loading rates. The effect of loading rate is also examined on reference transition temperature using Wallin’s correlation based on Zener-Hollomon strain rate parameter. |
