Solution combustion synthesis of nanocrystalline Fe-50%Ni alloy powder

Nanocrystalline Fe-50%Ni powder was synthesized via solution combustion process followed by hydrogen reduction, The influence of glycine to ferric nitrate ratio (G/Fe) on the combustion behavior and morphology evolution of the combusted powder was investigated. The effect of reduction temperature on the morphology and crystallite size of the obtained gamma-Fe50%Ni powder was characterized. Porous gamma-Fe-Ni powder with crystallite size below 100 nm was obtained after reduction. The Fe-50%Ni powder reduced at 700 degrees C has the maximum saturation magnetization and the minimum coercivity values of 15633 emu/g and 37.2 Oe, respectively. (C) 2014 Elsevier B.V.
