Abstract
PROCEDIMIENTO PARA OBTENER UN ARTICULO DE PULVIMETALURGIA. SE PRODUCE UNA CARGA DE PARTICULA DE UNA ALEACION QUE CONSISTE EN 0,2 A 1,5% EN PESO DE MAGNESO, HACIA 2% EN PESO DE SILICONA, DE 1,5 A 6% EN PESO DE CROMO, DE 0,5 A 6% EN PESO DE MOLIBDENO, HASTA 0,3% EN PESO DE AZUFRE, DE 7 A 10% EN PESO DE VANADIO, MAS DE 0,25% EN PESO DE CARBON, HASTA 40% EN PESO DE VANADIO Y EL RESTO DE HIERRO Y ELEMENTOS ACCIDENTALES, CONTROLANDO LA CANTIDAD DE CARBON RESPECTO A LA DE VANADIO PARA QUE NO EXISTA CARBON EN LA MATRIZ DE ACERO. SE COMPACTA LA CARGA DE PARTICULA POR UNA COMBINACION DE CALOR Y PRESION PARA FORMAR UNA MASA COHERENTE QUE TENGA UNA DENSIDAD EN EXCESO DEL 99% DE DENSIDAD TEORICA, CALENTANDO A TEMPERATURA DE AUSTENIZACION Y ENFRIANDO DESDE LA MISMA HASTA AQUELLA QUE CONSIGUE UNA ESTRUCTURA MARTENSITICA TOTAL. SE UTILIZAN DICHOS ARTICULOS PARA LA FABRICACION DE LAMINADOS EN CALIENTE Y HERRAMIENTAS, ASI COMO UTILES EN FRIO.
