Description	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 450–530 oC). 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 and solidsolution 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.
