Advanced high strength steel (AHSS) TWIP: A door to the future in metal forming

Abstract

The last decades have been characterized by a fast evolution of cars. This work shows the evolution of vehicle weight. It shows the response of car manufacturers using new materials and production methods that allow lighter vehicles with lower consumption, cheaper and with lower influence on the greenhouse effect. One of the materials which means a most interesting change is the TWIP steel. This material is characterized by its high strength, his exceptional strain and excellent formability as well as lower energy consumption in their manufacture. TWIP steel are changing towards cheaper compositions and higher performance, and it's going to be great influence in the vehicle weight reduction in the next years.
