| Inverse relation exists between the hardness and coercivity change within the whole period of structural relaxation in the investigated Fe-B(Si) based metallic glasses. This relation is independent of B-content and composition. This inverse relation is no more valid in binary Fe-B glasses after the onset of crystallization, when both the hardness and coercivity exhibit rapid increase. In contrast, the inverse relation was in FINEMET type glasses between these properties preserved in the first step of crystallization during the whole period of nanocrystallization. |
