En este proyecto se propone estudiar el comportamiento de distintos aceros empleados en plantas industriales de nuestro medio (generadoras de electricidad, industria petroqu\u00edmica, talleres aeronavales, etc.) donde los componentes est\u00e1n expuestos durante largos per\u00edodos de trabajo a altas temperaturas y presiones, que aumentan el riesgo de la degradaci\u00f3n del material. <\/p>\n

Entre los principales mecanismos de da\u00f1o a que se someten los materiales se puede mencionar el creep, la fatiga, o la interacci\u00f3n creep-fatiga. Si la carga es constante y el material est\u00e1 sometido a alta temperatura, se producir\u00e1 una deformaci\u00f3n continua en el tiempo que producir\u00e1 una falla por termofluencia (creep); en cambio si el material est\u00e1 sometido a cambios c\u00edclicos de temperatura y\/o tensi\u00f3n se produce fatiga y si se dan los dos fen\u00f3menos simult\u00e1neamente entonces se produce una interacci\u00f3n creep – fatiga.<\/p>\n

En especial este fen\u00f3meno, tiene un efecto muy perjudicial sobre la duraci\u00f3n de los componentes; se sabe que las deformaciones por creep reducen la vida a la fatiga y\/o las deformaciones por fatiga disminuyen ampliamente la vida al creep.<\/p>\n

La cuantificaci\u00f3n de estos efectos resulta de gran importancia cuando se pretende predecir la vida de un componente ya que el desarrollo del da\u00f1o depende de la temperatura, la velocidad de deformaci\u00f3n, tiempo de permanencia de las tensiones o de los ciclos y de la resistencia del material.<\/p>\n

En forma simult\u00e1nea se pretende, adem\u00e1s de conocer los mecanismos de deformaci\u00f3n que operan, analizar la evoluci\u00f3n de la microestructura bajo las condiciones de servicio.<\/p>\n \n
