Structural transformations of Fe81B13Si4C2 amorphous alloy induced by heating

Popis výsledku v původním jazyce

Thermal stability and crystallization of theFe81B12Si4C2 alloy were investigated in the temperature range 25?700 oC by the XRD and Mössbauer analysis. It was shown that on heating the as-prepared amorphous Fe81B12Si4C2 alloy undergoes thermal stabilization through a series of structural transformations involving the process of stress-relieving (temperature range 200?400 oC), followed by a loss of ferromagnetic properties(Curie temperature at 420 oC) and finally crystallization (temperature range 450?530oC). The process of crystallization begins by formation of two crystal phases: Fe3B and subsequently Fe2B, as well as a solid solution a-Fe(Si). Within crease in annealing temperature, the completely crystallized alloy involved only two phases,Fe2B andsolidsolution a-Fe(Si). XRD patterns established a difference in phase composition and size of the formed crystallites during crystallization depending on the side(fishy or shiny)of the ribbon.
