Abstract

 Bars of 4340 steel were heat treated to produce steel with different microstructures, i.e. tempered martensite, lower bainite and ferrite-bainite microstructures. Fatigue test results showed that the fatigue limit of steel with a ferrite-martensite microstructure is greater than the fatigue limit of the other two microstructures. The greater fatigue limit of ferrite-martensite steel is related to the initiation of secondary cracks from the original crack and a slower fatigue crack propagation rate in this microstructure, due to the ductile ferrite phase. Calculation of fracture toughness from impact energy showed that ferrite-bainite steel has greater fracture toughness than the other two microstructures.
