Avaliação de aços ao manganês para a indústria automobilística

Abstract

Oil is a source of fuel that has enabled one of the greatest cultural and economic transformations since the period of the first industrial revolution. However, it is also one of the biggest environmental problems, in addition to being frequently impacted by political issues. Its relevance increases in the interwar period during the 20th century, with the growth and increase in automobile productivity. In this context, Materials Engineering has the challenge of being what it proposes: a means to an end in other Engineering schools. The application of advanced high strength and low density steels therefore becomes a necessity. However, the area lacks in-depth studies so that it can be used on a large scale. To serve as a basis, the present work focused on the existing literature, counting on reading approximately 25 articles and book chapters. In addition, based on one of them, three Fe-25Mn-(3-8)-Al-C alloys were selected for evaluation of the formed phases and density, both as a function of temperature using the thermodynamic software Thermocalc®.
