PADMANABHAN South Asia International Institute, Mahavir Chambers, Liberty Crossroads, Hyderabad-500029, India Due to cost effective processing, medium carbon microalloyed steels are replacing quenched and tempered alloy steels in automotive applications. To be able to substitute alloy steels, microalloyed steels must be thermomechanically processed to similar strength levels, along with an acceptable level of toughness [1]. Recently a multiphase microstructure was obtained in a medium carbon microalloyed steel through a two-step cooling and annealing procedure following controlled forging. The tensile and the low cycle fatigue (LCF) behavior in this condition is now established [2, 3]. It is known that such a high strength multiphase steel displays cyclic softening during fatigue testing, especially under high total strain amplitudes. It was also established that this multiphase steel is cyclically stronger than the same material having a pearlite-ferrite or tempered martensite microstructure [3]. In this paper,
