Abstract

Dual phase steels (DP S) with a microstructure consisting of a hard second phase (martensite) embedded in a ductile matrix (ferrite) are very useful as their composite type microstructure. This combination could enhance the strength and ductility. It is therefore interesting to investigate the deep drawing behavior of them. Wrinkling can occur in the critical regions of the blank submitted to compressive stresses. In this work, effects of blank- holder force, blank diameter and martensite phase percentage were studied on the wrinkling behavior of DPS. Low-carbon steel (0.08wt%C) was used for making DP S with different martensite percentage. An increase in the martensite percentage leads to superior strength associated with reduced ductility and it can change the response of material against deep drawing. As expected, the number of wrinkles decreases as the blank diameter increases. However when the blank diameter was increased the probability of occur tearing was increased.
