Abstract
In recent decades the increasing competition and growing demand for light weight, high performance and crashworthiness structures in the automotive vehicle forced steel industry, automakers and the scientific community to focus more on efficient manufacturing. As a result of these, a significant increase in the usage of steel structures in automobiles was observed in last decade - especially Advanced High Strength Steels (AHSS) parts. These steels are one of the bets of the automotive industry to reduce the vehicle weight and thus reduce fuel consumption. The aim of this study was to analyze the tensile and stamping, the main mechanical properties of AHSS, since the beginning of deformation until the moment of fracture. AHSS as DP (Dual Phase), CP (Complex Phase) and TRIP (Transformation-Induced Plasticity). Were also used HSS (High Strength Steel), highlighting the HSLA (High Strength Low Alloy), micro-alloyed steels and even carbon steels. Not forgetting that the main objective is the study of AHSS, these other steels only served as a basis of comparison. Once all the properties were determined, it was possible to compare all the materials, determining the application of each steel replacing the conventional steels currently used in automobiles, in order to reduce weight and consequently the decrease in fuel consumption and pollution. Replacing the structural part of the automobiles, conventional steels by advanced high strength steels 35% more resistant, it may be possible to reduce the thickness of parts by 35%, thereby reducing total mass is 8.3% and fuel consumption of 6.6%.
