Previous work has reported on initiation and propagation of fatigue cracks from machined notches in cast steels. That work is extended here to notches of 12.5 and 25.4 mm radii with sand-cast surfaces. The comparison of initiation lives of machined and cast notches allows calculation of the effective notch radius arising from the cast surfaces. This effective radius is, in all cases, significantly less than the macroscopic notch radius and is a practical and important factor in the design of steel castings facing fatigue service conditions.
