Advanced high strength steels play a pivotal role towards achieving the desired structural characteristics of the motor vehicles. Many structural components have been replaced by advanced high strength steels like IF steel, Bake hardening steel, HSLA steel, Micro alloyed steel, Dual Phase steel, Ferrite Bainite steel, Martensitic steel, Hot formed steel, TRIP steel, TWIP steel etc. along with austenitic and ferrite grade stainless steels due to its superior strength and ductility. In the current context it has been attempted to see the causes behind the development of those mentioned steels from conventional to third generation as well the strengthening mechanisms employed towards the development of advanced high strength structural steels. It has been observed from literature study that substantial development have been progressed from metallurgica ...
