STUDY OF THE CRYSTALLIZATION OF FE78-XMOXSI9B13 AMORPHOUS-ALLOYS

The partial replacement of Fe atoms by Mo ones in amorphous Fe78Si9B13 alloys weakens their magnetic properties and shifts the crystallizati on process to higher temperatures. The crystallization is completed in three stages: During the first two, BCC Fe[Si,Mo] and BCT or orthorho mbic [Fe,Mo](3)B phases are formed, respectively, the Mo content in th ese phases being less than 2 at%. The crystallization gets completed d uring the third stage, taking place at higher temperatures, where crys talline phases richer in Mo are formed. (C) 1998 Elsevier Science B.V. All rights reserved.
