Application of energy-filtering TEM to the nanocrystallization process in amorphous Fe84Nb7B9 alloy

Journal of Materials Science Aims and scope Submit manuscript

The nanocrystallization process in amorphous Fe84Nb7B9 alloy was studied by means of energy-filtering transmission electron microscopy. Energy-filtered diffraction intensity provided quantitative structural analysis for the as-quenched state with the help of reverse Monte Carlo simulation. Using the Fe L-edge it was found from chemical mapping that chemical segregation of Fe with Fe-rich and Fe-poor regions starts to occur at the later stage of nanocrystallization.
