Abstract

PROCEDIMIENTO PARA PRODUCIR UNA ALEACION DE ACERRO INOXIDABLE. COMPRENDE: A) AÑADIR A UNA CANTIDAD DADA DE FE, UNA CANTIDAD PRESELECCIONADA DE ELEMENTOS FORMADORES DE FERRITA (CR, MO, SI) DE ELEMENTOS FORMADORES DE AUSTENITA (C, N, CO, NI, MN) Y ELEMENTOS QUE INCREMENTAN Y DISMINUYEN LA ENERGIA POR EFECTO DE APILAMIENTO, PARA FORMAR EN UN 60% DE LA ALEACION UNA FASE METAESTABLE DE ALEACION CUBICA CENTRADO EN LAS CARAS QUE PUEDA TRANSFORMARSE EN LA FASE E COMPACTA HEXAGONAL Y/O FASE MARTENSITA A DE PEQUEÑA GERMINACION POR DEFORMACION Y B) COLAR LA MEZCLA DE ALEACION, PARA OBTENER UNA ALEACION DE ACERO INOXIDABLE DOTADA CON ELEVADA RESISTENCIA A LA CAVITACION Y FORMADA POR 8 A 30% A CR, 0,03 A 0,3% DE C, 0,3 DE N, 3% DE SI, 1F% NI, 2F% MO, 9% DE MN Y EL RESTO FE. SE UTILIZA PARA PREPARAR COMPONENTES DE MAQUINAS HIDRAULICAS SOMETIDAS A PROCESOS DE CAVITACION.
