 note = {Change of strain amplitude, maximum strain and residual strain during torsional fatigue by Ni-Cr-Mo and Cr-Mo steels for constructional use, are shown in this paper. Results for both steel by mean stress of 0～40kg/mm^2 are as follows. Strain amplitude and maximum strain increase from about 10^4 reversal of stress for fatigue limit and reach to maximum at about 3～5×10^5 then settle to certain values. They increase monotonously when the specimens break down. Amounts of both change are larger by Cr-Mo steel than Ni-Cr-Mo steel. Results for Ni-Cr-Mo steel having residual strain by pre-stressing of 60～80 kg/mm^2 are as follows. Torsional fatigue limit decreases a few for pre-stress up to about 70 kg/mm^2. Strain amplitude and maximum strain decrease slightly from about 10^4 reversal of stress for fatigue limit, but the amount of change are small. Pre-worked residual strain decreases gradually and residual stress is thought to decrease also., 資料番号: SA1511611000},
