| Abstract: | The structural relaxation process of amorphous alloys Fe79Si7B14 and Fe833Si4B10C3 have been investigated by differential thermal analysis and Mossbauer technique. The experimental results obtained show that the structural relaxation associates with topographical short range ordering, chemical short range ordering and nucleation growth of base metal phase, relatively, in different temperature region. |
