The influence of Y and Al alloying on the glass-forming ability of bulk metallic glasses of the Fe40–50.4(TM, Al)29.1–37.5Y0–2(Si, C, B)19.7–22 system alloys with different content of transition metals (TM) and metalloids is investigated. An extensive analysis of the amorphization tendency of the studied alloys is carried out with a comparison of the effectiveness of several criteria. In rapid-quenched bulk samples of the complex alloyed alloys studied in the article, a number of non-equilibrium structures are observed (namely, purely amorphous, amorphous–crystalline (nanocomposite) and nanocrystalline ones) that indicates a significant dependence of the structure of this group of alloys on cooling conditions. As shown, the main factor determining the amorphization tendency of Fe-based alloys is the proximity of the alloy composition to the eutectic. Alloying the alloys with yttrium and aluminium significantly increases the melt amorphization tendency.
Key words: eutectic alloys, nanocrystallization, amorphization, melt quenching, bulk metallic glasses, glass-forming ability.
