Résumé | Copper is often used in steel powder metallurgy due to its significant strengthening effect. The large difference in solubility of copper in austenite at sintering temperatures and in ferrite at room temperature can lead to precipitation hardening. Work was carried out to gain a better understanding of the strengthening mechanisms associated with copper. Microhardness measurements combined with X-ray energy dispersive spectrometry (EDS) in a scanning electron microscope were used to quantify the strengthening effect of copper in pearlite and in martensite. Transmission electron microscopy was used to observe nanometer-sized copper precipitates. The detailed characterization of the microstructure and properties contribute to a better understanding and use of copper in sintered steel parts. |
