【Abstract】 The properties and the carbon content of MIM Fe/2Ni alloy sintered in H 2, H 2+N 2(at different H 2/N 2)atmosphere and vacuum were investigated. It is concluded that the properties of MIM Fe/2Ni alloy are highly dependent on the carbon content which is influenced by the content of H 2 in H 2+N 2 atmosphere since the carbon content in alloy decides the final microstructure of the alloy. Thus the appropriate properties can be available by controlling the H 2 content in H 2+N 2 atmosphere. The mechanism of carbon decarbonization of Fe/2Ni alloy was also discussed. [更多还原
