Abstract
PROCEDIMIENTO DE OBTENCION DE PIEZAS MECANICAS REALIZADAS A PARTIR DE POLVO DE ALEACION DE ALUMINIO. COMPRENDE: A) UTILIZAR UN POLVO PREALEADO DE ALEACION DE ALUMINIO TIPO 2214 AU 4 SG; B) DENSIFICAR EN FRIO DE FORMA ESBOZADA Y SENCILLA, EN UNA PRENSA INDUSTRIAL PARA OBTENER UNA FORMA ESBOZADA DE DENSIDAD MODERADA, 2 A 2,5; C) PESAR AUTOMATICAMENTE LA FORMA ESBOZADA AL SALIR DE LA PRENSA PARA CONTROLAR QUE EL PESO DE LA FORMA ESBOZADA SEA DE G 0,5%; D) CALENTAMIENTO DE LA FORMA ESBOZADA A UNA TEMPERATURA COMPRENDIDA ENTRE 470 Y 500JC, EN ATMOSFERA DE NITROGENO PURO; E) SACAR LA FORMA ESBOZADA DEL HORNO Y FORJARLA EN UN TIEMPO INFERIOR A LOS 10 SEGUNDOS EN UNA MATRIZ CERRADA, SIN REBABAS GRUESAS. LA DENSIFICACION FINAL AL 100% SIN POROSIDAD SE EFECTUA AL MISMO TIEMPO QUE LA FLUENCIA EN ESTADO SOLIDO DEL METAL EN LA ESTAMPACION. LA ESTRUCTURA DE MATRIZ ES HOMOGENEA Y MUY FINA CUYOS GRANOS TIENEN UN TAMAÑO DEL MISMO ORDEN DE MAGNITUD QUE EL DE LOS GRANOS DE POLVO INICIALES, EN LA QUE SUBSISTEUNA RED FINA DE PRECIPITADOS INTERGRANULARES.
