Estudio de las características mecánicas de aleaciones de Ti conformadas mediante pulvimetalurgia

Abstract

En este proyecto se han estudiado las características mecánicas de tres materiales: Titanio HDH, Ti 6Al 4V prealeado y Ti 6Al 4V máster aleación. Los materiales han sido fabricados en el Departamento de Ciencia e Ingeniería de Materiales de la Universidad Carlos III de Madrid, y han sido conformados mediante pulvimetalurgia. Los tres materiales han tenido el mismo proceso de fabricación, compactación mediante compresión uniaxial y sinterización en vacio a 1250 ºC durante 2 horas. La caracterización mecánica se ha realizado en el Departamento de Ciencia de Materiales de la Universidad Politécnica de Madrid. Para la determinación de las características mecánicas se han realizado ensayos a distintas temperaturas (25, 200 y 400 ºC) de flexión en tres puntos con y sin entalla, y se ha realizado un análisis fractográfico con imágenes de las fracturas obtenidas mediante un microscopio electrónico de barrido (MEB). De los ensayos realizados a estos materiales se han obtenido valores de sus propiedades mecánicas. En concreto se han obtenido valores de Módulo de elasticidad, límite elástico, tenacidad a fractura y energía absorbida durante la fractura. En la Universidad Carlos III se realizó una primera caracterización mecánica, como referencia, que junto a la bibliografía existente ha servido para comparar y explicar los resultados obtenidos. ________________________________________________
