Abstract
This paper investigates the effect of laser hardening on cracked steel specimens. After laser hardening around precracked shafts of SAE 1015 steel, rotary bending fatigue strength was determined. The results showed that the fatigue strength of specimens with a small crack can be raised to the strength of virgin specimens. Therefore this method may be used as a technique for fatigue fracture prevention of steel components containing cracks.Keywords
