Abstract:

The 11.3 nm diameter nanopowders of Ni dominated Ni(Fe) solid solution can be prepared by using aluminum powder to react with FeSO4. (NH 4)2 SO4 and NiSO4. (NH4)SO4 mixed solution. In the product, the Fe atoms replaced parts of the Ni atoms.  While the mass fraction of Ni 2+ /(Fe 2+ +Ni 2+ ) in the solution  is higher than 76%, solid solution of homogenous phase Ni(Fe) can be obtained. If the content ofNi 2+ /(Fe 2+ +Ni 2+ ) lower than this point, the Ni(Fe)+Fe or Fe+Ni 0.36 Fe 0.64 mixed phase nanopowders will be produced.

Key words: Ni(Fe)alloy; Solid solution; Nanopowders; Fe 0.64 Ni 0.36
