Notes:
Interstitial free (IF) steels are widely used as thin sheet in the automobile industriesbecause of their many favorable properties. Although, fatigue properties of IF steels do not havesignificant importance to auto body makers, however, they are very concerned about the tensile andfatigue strength of the steels used for structural purposes to ensure safety of passengers. So, fatigueresults of this steel might help researchers to understand the behaviors of high strength steels. In thisstudy cyclic and static properties have been studied at room temperature in the air. Initiative hasalso been taken to observe the fatigue fracture morphology of this steel. Experimental results showthat the fatigue limit is corresponding to about 40% of tensile strength and 80% of the yield strengthof this steel. Fractographic observations reveal a mixed type of fracture mode (intergranular andtransgranular cracking) fractures
