UN CUERPO DE CARBURO CEMENTADO PROVISTO DE UNA RESISTENCIA MEJORADA A LA FATIGA MECÁNICA. EL CUERPO DE CARBURO CEMENTADO COMPRENDE TANTALIO EN EL MATERIAL DE MATRIZ AGLUTINANTE. EL CONTENIDO DE TANTALIO SE ENCUENTRA ENTRE 1,5 POR CIENTO EN PESO Y 3,5 POR CIENTO EN PESO DEL CONTENIDO DE AGLUTINANTE. EL AGLUTINANTE COMPRENDE INCLUSIONES QUE CONTIENEN TANTALIO QUE TIENEN UNA DIMENSIÓN LINEAR PROMEDIO NO MAYOR QUE 80 NM. A cemented carbide body is provided with improved resistance to mechanical fatigue. The cemented carbide body comprises tantalum in the binder matrix material. The tantalum content is between 1.5 weight per cent and 3.5 weight per cent of the binder content. The binder comprises tantalum-containing inclusions having a mean largest linear dimension of no more than 80 nm.
