Abstract

SE PRESENTA UN METODO MEJORADO PARA FABRICAR UNA BANDA DE ALEACION DE ZIRCONIO-4. EL METODO ES DEL TIPO DE LOS QUE EL MATERIAL DE ALEACION DE ZIRCONIO-4 SE FUNDE AL VACIO, SE FRAGUA, SE REDUCE MEDIANTE CALOR, SE RECUECE Y SE TEMPLA, SE LAMINA MEDIANTE CALOR, SE EXPONE A UN POSTERIOR PROCESO DE RECOCIDO Y POSTERIORMENTE SE REDUCE MEDIANTE AL MENOS DOS PASOS DE LAMINADO EN FRIO, QUE INCLUYEN UN LAMINADO EN FRIO FINAL PARA OBTENER EL TAMAÑO FINAL, CON UN PROCESO DE RECOCIDO INTERMEDIO ENTRE LOS PASOS DE LAMINADO EN FRIO Y CON UN RECOCIDO FINAL DESPUES DEL ULTIMO PASO DE LAMINADO EN FRIO. LA MEJORA SE CARACTERIZA POR LOS SIGUIENTES PASOS: A) UTILIZAR UNA TEMPERATURA DE PROCESAMIENTO MAXIMA DE 620 C ENTRE EL TEMPLADO Y EL LAMINADO EN FRIO FINAL PARA OBTENER EL TAMAÑO FINAL; B) EFECTUAR UN RECOCIDO PARA SU ENDURECIMIENTO A UNA TEMPERATURA MAXIMA INTERMEDIA DE RECOCIDO DE 520 C; Y C) UTILIZAR COMBINACIONES DE TIEMPO/TEMPERATURA DE RECOCIDO EN CALIENTE, RECOCIDO INTERMEDIO Y RECOCIDO FINAL QUE DANUN PARAMETRO A DE ENTRE 4 X 10 ELEVADO A -19 Y 7 X 10 ELEVADO A -18 HORAS, DONDE LOS PARAMETROS DEL SEGMENTO SE CALCULAN PARA EL PASO DE LAMINADO EN CALIENTE Y CADA PASO DE RECOCIDO, LOS PARAMETROS DEL SEGMENTO SE CALCULAN TOMANDO EL TIEMPO, EN HORAS PARA EL QUE SE REALIZA ESE PASO, EL EXPONENTE DE LOS TIEMPOS DE (-40,000/T), EN EL CUAL T ES LA TEMPERATURA EN GRADOS K, EN LA QUE SE REALIZA EL PASO, Y DONDE EL PARAMETRO A ES LA SUMA DE LOS PARAMETROS DE SEGMENTO. PREFERIBLEMENTE EL LAMINADO EN CALIENTE Y EL RECOCIDO POSTERIOR AL LAMINADO EN CALIENTE SE HACEN 560-620 C Y DURANTE 1.5-3 HORAS Y EL RECOCIDO INTERMEDIO SE HACE A 400-520 C Y DURANTE 1.5-15 HORAS Y EL RECOCIDO FINAL DESPUES DEL ULTIMO PASO DE LAMINADO EN FRIO SE HACE A 560-710 C DURANTE 1-5 HORAS, Y EL RECOCIDO BETA SE HACE A 1015-1130 C DURANTE 2-30 MINUTOS.
