Influence of thermal treatment on microstructure of Fe75Ni2Si8B13C2 amorphous alloy

Popis výsledku v původním jazyce

DSC and thermomagnetic measurements of Fe75Ni2Si8B13C2 amorphous alloy investigated in 298e973 K temperature range show that alloy remains amorphous up to around 773 K. As thermomagnetic measurements provided more complete information, the alloy ribbon was successively annealed at temperatures chosen on the basis of these measurements and its microstructure was investigated after each annealing cycle using X-ray diffraction and SEM. Two stable, a-Fe(Si) and Fe2B, and one metastable, Fe3B, crystalline phases were identified after annealing. Microstructural analysis showed that Fe3B probably acts as an intermediate in the formation of Fe2B, which formed later than the other two phases. Si and B in the alloy show a tendency to separate into different phases. Analysis of microstructure, combined with chemical composition, showed that after the final annealing at 973 K, alloy ribbon is composed of interdispersed nanocrystals of alpha-Fe(Si) and Fe2B less than 90 nm in size, with no observab
