Nanocrystallization and phase formation in Fe73:5Nb3Cu1Si15:5B7 amorphous ribbon under laser heating

Nanocrystallization and phase formation in Fe73:5Nb3Cu1Si15:5B7 amorphous ribbon under laser heating

Laser-induced local crystallization in Finemet-type alloy was studied using X-ray diffraction, SEM and EDX methods. For investigated conditions of irradiation (wavelength λ = 1.06 μm, laser power density 50 W/cm2), it was found that primary crystallization starts with the formation of the nanocrysta...

For investigated conditions of irradiation (wavelength λ = 1.06 μm, laser power density 50 W/cm2), it was found that primary crystallization starts with the formation of the nanocrystalline α-Fe(Si) solid solution at shorter exposure time and the second step crystallization with the nanocrystalline hexagonal H-phase formation occurs in longer exposure time.

It was shown that the nonlinear temperature field due to the laser irradiation resulted in changes of the local elements concentration and this feature changed crystallization mechanism of the Finemet-type alloy.https://doi.org/10.2478/msp-2020-0064laser-induced crystallizationamorphous metallic alloynanostructure
