説明
Rotating bending fatigue tests were carried out using partially notched specimens of Ni-base super alloy Inconel 718 at room temperature in order to investigate the effect of aging condition on fatigue properties. Aging conditions selected were the under-aged and the over-aged conditions with the same hardness and the peak-aged condition. The conventional double-aged condition was also selected for comparison. Fatigue strength of the double-aged condition was the highest among the alloys, especially at fatigue limit. The growth rate of a crack smaller than the length of a few grains was suppressed in the double-aged alloy, though the growth rates of a longer crack were nearly the same in all of the alloys.
