抄録

The rotating-beam fatigue tests with comparatively shallow notches are conducted on two grades of commercially pure titanium and the fatigue strengths are measured at 107 cycles. The notched fatigue strength increases beyond that of unnotched specimen as it iocreases remarkably in sharpness of the notch untill the theoretical stress concentration for the notch reaches 1.2 and decreases gradually with further notching. The notched fatigue strength for theoretical stress concentration of about 2.0 or less is higher than that of the unnotched specimen. In the case of shallow-notched specimens with theoretical stress concentration less than 1.2, an internal heating phenomenon same as in the case of unnotched specimens is observed. When those specimens are tested in water, the increase in fatigue strength is not exhibited on account of the cooling effect. It is considered that the increase in fatigue strength of shallow-notched specimens is related to the internal heating phenomenon.
