The strain fatigue,impact fatigue and rotation beam fatigue behaviour of granular bainitic structure has been studied.The results show that the strain fatigue properties and the impact fatigue properties of granular bainite are superior to that of tempered martensite under the condition that the ultimate tensile strength is equal.The impact.fatigue life increases with in- creasing amount of granular bainite,because the M-A islands might retard the propagation of fatigue crack.The rotation beam fatigue properties of granular hainite are similar to that of tempered martensite.The relationship between.fatigue limit S_f,yield strength σ_y and frac- ture strength S_k may be expressed as S_f=4.651+0.1411(σ_y+S_k)
