Abstract The changes of local structures around Fe and Zr atoms in the nanocrystalline films of Fe85Zr9B6 and Fe84Zr9B6 Cu1 alloys during annealing process were investigated by extended X-ray absorption fine structure (EXAFS) technique. It is confirmed that Zr atoms always exist in amorphous phase and do not dissolve in the bcc $\alpha$-Fe crystalline phase. The addition of 1 at% Cu lowers the crystallization temperature.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
