Abstract

The threshold stress intensity factor range (ΔK_th) of water-quenched Fe-0.017C (wt.%) fully ferritic steel was determined using room-temperature fatigue tests on micro-notched specimens. The experimentally determined ΔK_th was approximately 40.5% higher than conventionally predicted results. This extraordinary resistance to transgranluar fatigue crack propagation likely results from the strain-age hardening.
