Structural relaxations in Fe-Co-Si-B amorphous alloys

The structural relaxation involved in the thermal treatment of Fe--Co--Si--B metallic glasses and the crystallization process as a function of cobalt content have been investigated. Magnetic measurements and the Mossbauer temperature scanning method for measuring the Curie temperature were used. One...

Zusammenfassung:	The structural relaxation involved in the thermal treatment of Fe--Co--Si--B metallic glasses and the crystallization process as a function of cobalt content have been investigated. Magnetic measurements and the Mossbauer temperature scanning method for measuring the Curie temperature were used. One stage of structural relaxation > 570K in metallic glasses with composition Fe sub 78--x Co sub x Si sub 9 B sub 13 was observed. This stage is characterized by a change of the chemical short-range ordering. The crystallization process detected by the magnetic measurements proceeds in two and in some cases in three steps.
