A Review on the development of 3rd generation advanced-high strength steels (HSS)

Abstract


Conventional-high strength steels (HSS) are an integral part of the automotive bodies for many years by the automotive industries due to their high strength. The 1st-generation advanced HSS with ferrite in the microstructure provides high strength than the conventional-HSS but failed to give sufficient ductility. The 2nd-generation advanced HSS enhance the ductility of the advanced-HSS. But the presence of more alloying elements cost the 1st- and 2nd-generation advanced-HSS. With the addition of a less amount of alloying elements, the 3rd-generation advanced-HSS gives a better combination of strength and ductility at a low cost. The 3rd-generation advanced-HSS generates multiphase microstructure (ferrite, martensite, retained austenite, bainite
