“…Influence of microstructure on fatigue crack growth was studied by Li et al [13], their results showed a lower fatigue crack growth rate for martensitic-ferritic microstructures than for ferritic-pearlitic microstructures. A higher proportion of martensite caused a slower fatigue crack growth rate.…”

“…Besides the effect of microstructure, residual stress is another significant factor that affects the fatigue crack behavior of surface strengthened materials. It was reported that compressive residual stress caused by un-uniform plastic deformation within the gradient layer, improved the fatigue resistance of 316 stainless steel, pure Cu and other alloys [7][8][9][10][11] and the gradient distribution of residual stress induced extra difficulty in the analysis of fatigue crack growth [25][26][27][28]. Thus, traditional fatigue theories which can describe the fatigue crack growth behavior in homogeneous materials are no longer applicable for the materials with gradient surface layer.…”

A B S T R A C TThis paper experimentally investigated the behavior of fatigue crack growth of an axle steel with a surface strengthened gradient microstructure layer. First, the microstructure, residual stress and mechanical properties were examined as a function of depth from surface. Then the fatigue crack growth rate was measured via three point bending fatigue testing. The results indicated that fatigue crack growth rate decelerated first and then accelerated with the increase of crack length within the gradient layer. Especially, the fatigue crack was arrested in the gradient layer under relatively low stress amplitude due to the increase of threshold value for crack growth within the range of 3 mm from surface. Based on these results, the parameters of Paris equation and the threshold value of stress intensity factor range within the gradient layer were determined and a curved surface was constructed to correlate crack growth rate with stress intensity factor range and the depth from surface. The effects of microstructure, residual stress and surface notch on the crack growth behavior were also discussed.
