- Abstract
10[sup 10]-cycle fatigue tests were conducted at 100 Hz for three years and at 20 kHz for one week on 1800 MPa-class JIS-SUP7 spring steel. Uniaxial tests up to 10[sup 8] cycles were also conducted at 120 and 600 Hz. The 120 Hz tests had larger control volumes. The fatigue limit at 10[sup 10] cycles was lower than at 10[sup 8] cycles, and any frequency effect was shown to be negligible. A size effect was found; the tests with larger control volumes showed results of lower fatigue strength.
