Abstract
Las aleaciones ferrosas, en particular los aceros, representan de lejos el material metálico más usado. Los aceros inoxidables destacan por tener la característica de no presentar corrosión fácilmente cuando son expuestos al ambiente. Debido a la popularidad que este material ha alcanzado en los últimos años, es preciso poseer un conocimiento pleno del comportamiento de éste cuando se va a fabricar una pieza con el fin de conseguir mejores calidades y reducir costes de fabricación.
Para conocer el comportamiento de un material es preciso realizar ensayos experimentales en el laboratorio. Sin embargo, esto resulta muy costoso. Como alternativa, se realizan estos ensayos mediante métodos numéricos, obteniendo resultados muy parecidos a los que se tendrían en ensayos experimentales.
Se realizarán ensayos numéricos que permitan predecir el comportamiento de los aceros inoxidables en las condiciones de mecanizado. Actualmente, el acero inoxidable más ampliamente usado es el acero 304, y su variante, el acero 304𝐿�����������, por lo que son éstos los estudiados en el presente proyecto. Ambos metales se usan indistintamente ya que sus propiedades y sus comportamientos son muy parecidos.
Las simulaciones numéricas, a través del software Abaqus/Explicit, proporcionarán resultados que posteriormente serán tratados para esclarecer el comportamiento durante el mecanizado del acero 304/304𝐿�����������, y validados por la literatura existente.
Ferrous alloys, particularly steels, represent by far the most widely used metallic material. Stainless steels stand out as having the characteristic of not easily corroded when they are exposed to the environment. Due to the popularity of this material has achieved in recent years, it’s necessary have a full understanding of the behavior of it when you are making a piece in order to achieve better quality and reduce manufacturing costs. Ideally, if you pretend to understand the behavior of a material, you need to carry out experimental tests in the laboratory. However, this is very expensive. Alternatively, these tests are performed using numerical methods on computers, obtaining very similar results to the experimental tests. Numerical tests will be carry out to predict the behavior of stainless steels in the machining conditions. Nowadays, the most widely stainless steel used is SS304, and its variant, SS304𝐿������, so there are those studied in this project. Both metals are used interchangeably because their properties and behavior are very similar. Numerical simulations will provide results through Abaqus/Explicit software that later will be processed to clarify the behavior of SS304/304𝐿������ and validated by literature.
