Study of Fe–Zr–U–B and Fe–Zr–U–Cu–B nanocrystalline alloys

Abstract The influence of uranium and copper additives on the crystallization process and magnetic properties was studied in Fe 87 Zr 7 B 6 amorphous alloys. The addition of copper resulted in homogeneous nanocrystalline precipitates and improvement of soft magnetic properties. The alloying with uranium led to the formation of inhomogeneous microstructure and increase in coercive force.
