Abstract

The structure of amorphous Fe100-xBx (17≤ × ≤ 50 at.%) alloys prepared by vacuum evaporating and by ns pulse laser melting of the same evporated layers has been compared using room temperature Conversion Electron Mössbauer Spectroscopy (CEMS). The width of the hyperfine field distribution (HFD) characteristic to the laser melted surface layer is 10% lower than that of the as received sample, being practically equal to the value observed for melt spun ribbons. A similar value was also found for the amorphous surface layer obtained by the laser melting of an Fe83B17 ingot consisting α-Fe and Fe2B crystals. It is established that a complete chemical mixing takes place during the life-time of the melt. The difference between the width of the HFD of evaporated and melt quenced alloys is attributed to an enhanced disorder in the evaporated sample.
