Microstructure and Property of Sintered Fe-2Cu-0.8C-0.6Mo-2W Materials Prepared From Prediffused Powders
Frontiers in Materials
Prediffused Fe-W powder with 2 wt% of tungsten was prepared by heating Fe-W powder mixes at 800°C for 45 min in H2 atmosphere. Two kinds of Fe-2Cu-0.8C-0.6Mo-2W powder mixtures were obtained by mechanically mixing the prediffused Fe-W powders with the other elemental powders. After pressing and sintering, the sintered Fe-2Cu-0.8C-0.6Mo-2W materials were obtained from the two powder mixtures.
