Tensile tests were carried out on FGH95 notched and unnotched little specimens at 550°C with loading rate ranging from 0.1 to 100 KN/min. The results show that nominal fracture stress decreases with an increasing in the loading rate, and decreases with elastic stress-concentration factor increasing only for the notched specimens with the same notch depth. With loading rate increasing, the coefficient of notch sensitivity Cm decreases for all specimens. The SEM analysis is consistent with the experimental results.
