New(Fe0.76Si0.09B0.1P0.05)98.25Nb1Cu0.75 bulk nanocrystalline alloys with good soft magnetic properties

A new(Fe0.76Si0.09B0.1P0.05)98.25Nb1Cu0.75 bulk nanocrystalline alloy in a rod shape with a diameter of 2.5 mm was successfully developed by copper mold casting and isothermal annealing. It was found that the introduction of Cu can result in the formation of a large number of α-Fe(Si)clusters(less t...

Zusammenfassung:	A new(Fe0.76Si0.09B0.1P0.05)98.25Nb1Cu0.75 bulk nanocrystalline alloy in a rod shape with a diameter of 2.5 mm was successfully developed by copper mold casting and isothermal annealing. It was found that the introduction of Cu can result in the formation of a large number of α-Fe(Si)clusters(less than 3 nm) embedded in the glassy matrix, which greatly improved the primary crystallization of α-Fe(Si) nanocrystals during subsequent annealing. The obtained superior soft magnetic properties can be ascribed to the formation of optimal nanocomposite structures with a large number of α-Fe(Si) nanocrystals( 17 nm) uniformly distributed in the glassy matrix.
