Processing of Cr-Mo Alloy Steel via PM Route
چکیده انگلیسی
Fe-Cr-Mo alloy steel with addition of 0.4 weight percentage graphite has been processed via Powder Metallurgy route. Green compacts prepared at 650 MPa pressure were sintered at 1120°C and 1200°C for one hour and cooled at 6.0°C/min in a stream of nitrogen and hydrogen (90%N2+10%H2). The sintered microstructure consists of a ferrite and pearlite with some cementite at the boundaries. Presence of chromium oxide was observed in samples sintered at 1120°C. In the present sintering conditions there was no significant difference in the density achieved at 1120°C and 1200°C. No oxide formation was observed at 1200°C. This resulted in improved mechanical properties as compared to specimen sintered at 1120°C.
