Abstract:Copper-infiltrated sintered steel is a prominent area of research in the field of powder metallurgy, with a particular focus on enhancing impact toughness. In this study, sintered steels with varying pore structures were prepared using iron powders and infiltrated with copper to investigate their impact toughness. The results indicate a significant improvement in the impact toughness of the sintered steels with concentrated iron particle sizes. The density of the samples increased from 6.85g/cm³ to 7.55g/cm³ t… Show more
