Processes nanocrystallisation in amorphous alloy of the system Fe-Cu-Nb-Si-B

The amorphous alloys of the system Fe-Cu-Nb-Si-B show the complex mossbauer spectrums with strongly overlapped lines. Together with lower sensitivity method XRD for unordered structure, detailed phase analysis is powerfully labored. It is shown, that many offered earlier phase compositions completely heating alloy not convincing. It is enough simply can be determined such parameters, as size nanocrystals, orientation primary magnetization in alloy or area of the temperature heating for nanocrystallization. Above temperature to primary crystallization 550$^\circ{\rm C}$ phase composition does not change. The size nanocrystalls remains constant in the field of the temperature heating from 550$^\circ{\rm C}$ to 710$^\circ{\rm C}$.
