The results of Stan ton and Bairstow (1908) have been reanalyzed to yield information on the composition dependence of the low cycle impact fatigue properties of pearlitic plain carbon steels. It has been found that the energy absorbed per impact, E i , and the number of impacts are failure, N f , are related by the equation: In this equation q is determined by the carbon, manganese and silicon contents of the steel; E o is the impact endurance limit; and C and D are constants. The curve represented by this equation intersects that representing the Johnson‐Keller high cycle impact fatigue equation at a value of log e N f equal to 1/C. Thus, the transition from low to high cycle impact fatigue occurs at this value of log e N f .
