En este trabajo se investigó el crecimiento de grietas por fatiga para diversas calidades de metal duro en función de la microestructura y el cociente de carga aplicada (R). De esta forma, se evaluó la influencia de la naturaleza química y el contenido del ligante (Co and 76wt%Co-24wt%Ni), así como del tamaño de grano de la fase cerámica, en el umbral (Kth) y en la cinética de la propagación de grietas por fatiga. Los resultados experimentales indican que las calidades con carburos gruesos presentan un mayor Kth que aquellas con un tamaño de grano medio. Esta mejora se asocia con la operatividad del mecanismo de deflexión de grieta. Los resultados señalan que los carburos cementados con base CoNi exhiben una dureza algo inferior que las cal...
