Abstract : Sintered Powder Metallurgy, P-M materials usually show brittle behaviour and for this reason its toughness is low if we compare it with wrought materials. Recently mechanical designers need more information about used materials and for this reason the knowledge of the behaviour of P-M materials under dynamic loading must be taken into account. In this work one step in this direction is made, studying the impact toughness behaviour of different P-M steels Fe-3.5% Mo prealloyed powders as base material and using the microstructure and fractography as tools for understanding the obtained results.
