Sintered (Powder Metallurgy, P/M) materials usually show brittle behavior a
nd for this reason their toughness is low compared with wrought materials.
The impact toughness behavior of different P/M steels (Fe-3.5% Mo pre-alloy
ed powders as base material) is presented and microstructural and fractogra
phical results are used to amplify the data. (C) 1999 Elsevier Science S.A.
