| Abstract Scope |
Ultra-high strength DP steels are being developed to help the automotive industry achieve better fuel efficiency and improved crash worhiness. These DP steels now contain low carbon content for spot weldability; high Mn, plus Cr and Mo for hardenability; and Nb and V. This paper will present recent research conducted on these kinds of steels. It will be shown that the choice of intercritical annealing temperature is important in microalloyed DP steels, and the rates of cooling throughout the CGL simulation are also important. Furthermore, the role of microalloying, especially V, in suppressing softening at or near the zinc pot temperature of 460°C has been shown to be important. The physical metallurgy of producing ultra-high strength steels on CG lines will be presented and discussed. |
