PURPOSE:To produce an iron-based powder composition for producing an iron- base, sintered part needing high density, high strength, toughness, wear resistance and high dimensional accuracy by powder metallurgy and to produce a sintering material from the composition. CONSTITUTION:At least one kind selected from an Fe-Ni alloy contg. 5-70wt.% Ni and an Fe-Mo alloy contg. 20-70wt.% Mo is deposited on the surface of an iron-base powder grain by a binder, heated and melted to obtain an iron-base powder composition for powder metallurgy. An iron-base sintering material to be compacted and sintered is produced from the composition. |
