| In this present study attempts have been made to synthesize Fe80B20 crystalline/amorphous nanocomposite powder by using surfactant-assisted high-energy ball milling. Comparison has been made for the differences in evolved microstructure via solidification and solid state phase transformation under equilibrium and non-equilibrium processing conditions. Structural analysis reveal that initially observed Fe2B and Fe3B intermetallic phases tend to disappear even at 1 h milling time and eventually lead to the stabilization of α-Fe nanoparticles and possible formation of amorphous phase by increasing milling time. This resultant structure governs the magnetic behaviour of the Fe80B20 nanoalloy. |
