Abstract

SE PRESENTA UN METODO PARA REDUCIR LA PROPAGACION DEL CRACKEO POR FATIGA EN SUPERALEACIONES BASADAS EN NIQUEL. EL METODO CONSISTE EN UN RECOCIDO DE SUPERSOLVUS EN QUE SE DISUELVE ESENCIALMENTE TODA LA FASE DEL PRECIPITADO GAMMA''. AL RECOCIDO DE SUPERSOLVUS LE SIGUE UNA REFRIGERACION LENTA QUE SE LLEVA A CABO A UNA VELOCIDAD QUE REDUCE SUSTANCIALMENTE EL CRECIMIENTO DEL CRACKEO POR FATIGA EN FUNCION AL TIEMPO PERO QUE MANTIENE LA RESISTENCIA DE LA ALEACION A UN NIVEL UTIL PARA MUCHAS APLICACIONES DE SUPERALEACION.
