Am. Glezer et Vi. Kirienko, TRANSFORMATIONS IN THE ALLOY FE-72.5-SI-13.5-NB-4-CU-1-B-9 WITH NANOCRYSTALLINE STRUCTURE, Russian metallurgy. Metally, (2), 1998, pp. 52-56
Structural changes on annealing the amorphous alloy Fe72.5Si13.5Nb4Cu1
B9 (Finemet) are investigated by autoionic microscopy. In the initial
stages of crystallization, metastable deposits of boride phase (5-9 nm
) are formed in the alloy along with nanocrystalline bcc phase Fe-Si.
