Resumo
The issue of developing new alloys for use in the automotive industry is so latent in the last 20 years, several projects are underway, involving the scientific community and steel manufacturers in the world. Steel sheets have various applications due to the ability to take the most varied profiles, through careful choice of the alloying and specifics heat treatments. The automotive industry is one of the highest markets for stamped parts and is thus a major driving force for the development of new materials and technologies in sheet metal area. 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 Advanced High Strength Steels, since the beginning of deformation until the moment of fracture. Advanced High Strength Steels were used as DP (Dual Phase), CP (Complex Phase) and TRIP (Transformation Induced by 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 Advanced High Strength Steels, these other steels only served as a basis of comparison. After certain all properties by tensile and stamping, was given a basis for comparison among all studied materials, so you can determine 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.
