Abstract

The cut-edge properties of automotive structures formed during the manufacturing processes significantly influence fatigue and formability performance of high-strength steels. This factor is becoming increasingly important as advanced high-strength transformation-induced plasticity TRiP-aided DP600 steels under examination exhibit an increased sensitivity to fatigue cracks initiating from mechanical cut-edges. It was determined that under prestraining, the effects of plastic deformation of the microstructure can be used to optimize fatigue life. This was particularly the case where the prestraining significantly improved the fatigue lives of mechanical cut-edges up to a prestrain level of 5%. It is proposed that the effect of prestraining can be used to optimize the fatigue lives of even damaged mechanical cut-edges. These parameters can be used in the manufacture of structures with both optimum formability and fatigue lives.
