Notes:
Fe-2Cu-2Ni-1Mo-0.8C (wt. pct) alloys were successfully fabricated from elemental mixedpowders by high energy milling and pulse electric current sintering, and the effects of milling timeand sintering parameters on the densification degree, microstructure, mechanical properties andfracture characteristic of sintered material were investigated. Results showed that with increasingmilling time, pulse electric current peak and sintering time, the density and transverse rupture strengthof sintered alloy were improved. However, higher pulse electric current peak and/or longer sinteringtime were unfavorable to the density and strength of sintered alloy, because of generating overhighsintering temperature. The density and transverse rupture strength of sintered alloy could reach 7.74[removed info]103 kg/m3 and 2231 MPa, respectively, and the corresponding fracture morphology wascharacterized as intergranular fracture
