Abstract

UN METODO PARA PRODUCIR UNA ALEACION DE AL-SI HIPEREUTECTICA FUNDIDA Y ALEACION OBTENIDA SEGUN DICHO METODO. UNA ALEACION DE AL-SI HIPEREUTECTICA FUNDIDA CON UN CONTENIDO DE SI DEL 12 AL 15% CON EXCELENTE RESISTENCIA, ASI COMO UN METODO PARA PRODUCIR DICHA ALEACION. LA ALEACION Y UNA MEZCLA USADA EN EL METODO CONTIENE SR EN EXCESO DE 0,10% Y TI EN EXCESO DE 0,005%, COMPRENDIENDO ADEMAS LA ALEACION: CU, 1,5 A 5,5%; NI, 1,0 A 3,00%; MG, 0,1 A 1,0%; FE, 0,1 A 1,0%; MN, 0,1 A 0,8%; ZR, 0,01 A 0,1%; ZN, 0 A 3,0%; SN, 0 A 0,2%; PB, 0 A 0,2%; CR, 0 A 0,1%; NA, 0 A 0,01%; B (ELEMENTAL), 0,05% MAXIMO; CA, 0,003% MAXIMO; P, 0,003% MAXIMO; OTROS, 0,05% MAXIMO CADA UNO, EL EQUILIBRIO ADEMAS DE IMPUREZAS INCIDENTALES, ES AL. EL NIVEL DE SR EN EXCESO DE 0,017% Y TI EN EXCESO DE 0,05% ES TAL QUE LA ALEACION TIENE UNA MICROESTRUCTURA EN LA CUAL TODO EL SI PRIMARIO FORMADO SE HALLA ESENCIALMENTE DISPERSO UNIFORMEMENTEY ESTA ESENCIALMENTE LIBRE DE SEGREGACION Y EN LA CUAL HAY PRESENTES PARTICULAS INTERMETALICAS DE SR DISPERSAS UNIFORMEMENTE.
