Abstract
SE PRESENTA UN NUEVO COMPUESTO PARA EL ACERO DE HERRAMIENTA DE POLVO-METALURGICO (PM), CARACTERIZADO POR LA AUSENCIA DE CO, REDUCCION DEL CONTENIDO DE W Y AUMENTO DE LOS CONTENIDOS DE MO Y V. ESTE ACERO CONTIENE (WT%), C DE 1.50 A 1.85, MN DE 0.20 A 0.55, SI DE 0.35 A 070, W DE 1.50 A 3.00, MO DE 8.00 A 9.50, V DE 5.50 A 6.50 Y CR DE 3.00 A 5.00, CONSTITUYENDO EL RESTO HIERRO E IMPUREZAS MENORES. EL POLVO UTILIZADO EN EL PROCESO DE FABRICACION SE OBTIENE MEDIANTE ATOMIZACION EN UN GAS QUE PUEDE SER NITROGENO O ARGON, SIENDO LAS RESULTANTES PARTICULAS DE FORMA ESFERICAS, 80% DE ELLAS DE TAMAÑO MENOR A 500 (MU)M. EL PROCESO DE FABRICACION COMPRENDE LAS SIGUIENTES ETAPAS: REFRIGERACION DURANTE LA SOLIDIFICACION DEL POLVO A UN NIVEL ENTRE 1000 Y 10000 NA PIEZA SEMITERMINADA TRANSFORMACION DEL PRODUCTO SEMITERMINADO EN EL DESEADO CALENTAMIENTO DEL PRODUCTO EN UN BAÑO-DE-SAL A UNA TEMPERATURA ENTRE 1160 Y 1200 URECIMIENTO EN UN BAÑO-DE-SAL A UNA TEMPERATURA ENTRE 450 Y 600 DE TRES TEMPLADOS SUCESIVOS A TEMPERATURAS ENTRE LOS 530 Y 560 C, ENTRE 540 Y 570 C Y NUEVAMENTE ENTRE 530 Y 560 C, CADA UNO DE ELLOS ENTRE UNA Y DOS HORAS. EL ACERO DE HERRAMIENTA, DE ESTA MANERA OBTENIDO, CONTIENE CARBUROS PRECIPITADOS DEL TIPO M2C-MC MIDIENDO MENOS DE 3.5(MU)M Y UNA FRACCION DE VOLUMEN ENTRE 13 Y 18%.A NEW COMPOUND IS PRESENTED FOR POWDER-METALLURGICAL TOOL STEEL (PM), CHARACTERIZED BY THE ABSENCE OF CO, REDUCTION OF THE CONTENT OF W AND INCREASE OF THE CONTENTS OF MO AND V. THIS STEEL CONTAINS (WT%), C OF 1.50 A 1.85, MN FROM 0.20 TO 0.55, SI FROM 0.35 TO 070, W FROM 1.50 TO 3.00, MO FROM 8.00 TO 9.50, V FROM 5.50 TO 6.50 AND CR FROM 3.00 TO 5.00, CONSTITUTING THE REST IRON AND MINOR IMPURITIES. THE POWDER USED IN THE MANUFACTURING PROCESS IS OBTAINED THROUGH ATOMIZATION IN A GAS THAT MAY BE NITROGEN OR ARGON, THE RESULTS BEING PARTICULAR IN A SPHERICAL FORM, 80% OF THEM SIZING LESS THAN 500 (MU) M. THE MANUFACTURING PROCESS INCLUDES THE FOLLOWING STAGES: REFRIGERATION DURING THE SOLIDIFICATION OF THE POWDER AT A LEVEL BETWEEN 1000 AND 10000 NA SEMI-FINISHED PIECE TRANSFORMATION OF THE PRODUCT SEMI-FINISHED IN A BATH-OF-SALT AND A TEMPERATURE AT 11 TEMPERATURE AT A TEMPERATURE AT A TEMPERATURE AT 11 PERCENTURE IN A BATH-DE-SALT AT 11 TEMPERATURE AT A TEMPERATURE AT 11 AM IN A SALT-BATHROOM AT A TEMPERATURE BETWEEN 450 AND 600 OF THREE SUCCESSIVE TEMPERATURES AT TEMPERATURES BETWEEN 530 AND 560 C, BETWEEN 540 AND 570 C AND AGAIN BETWEEN 530 AND 560 C, EACH OF THEM BETWEEN ONE AND TWO HOURS. THE TOOL STEEL, IN THIS WAY OBTAINED, CONTAINS PRECIPITATED CARBIDE OF THE M2C-MC TYPE MEASURING LESS THAN 3.5 (MU) M AND A FRACTION OF VOLUME BETWEEN 13 AND 18%.
