Abstract

Prealloyed steel powders with different amount of Mo-Cu-Ni-C were compacted at 700 MPa and sintered at 1120 °C in 95 % N₂-5 % H₂. After sinterizing, these materials were treated by carburizing. For materials characterization radial crushing strength were preformed, density was calculated and a complete study of fracture surfaces was carried out using scanning electron microscopy. The results of radial crushing strength show that resistance after carburizing is higher than in sintered materials. The fracture surfaces give an idea of materials briteless and the treatment depth. In sintered materials, a dúctil surface was observed, with the characteristic dimples. The fracture surfaces after different treatments show britelessnes in the outer zone, while inside appears a mix of dúctil and briteles fracture.
