Crystallization kinetics of nanocrystalline alloys revealed by in situ nuclear forward scattering of synchrotron radiation

Abstract

The nanocrystallization kinetics of Fe90Zr7B3 is investigated by in situ nuclear forward scattering of synchrotron radiation upon isothermal annealing. The nucleation and growth processes are accessed separately for the nanograins, their interfaces, and the residual amorphous matrix by monitoring the time evolution of the corresponding hyperfine parameters.

This approach discloses the structural transformations taking place in this class of technologically important materials.
