Centrally cracked specimens of JIS SM58Q and I-IT80 steels were fatigued. The fatigue crack growth rates, da/dn, and the stress intensity threshold levels, AK,, were measured over the range of stress ratio, R, from -1 to 0.8 by the use of an automatic method of continuously decreasing stress intensi
