%X This work investigates the glass formation of Fe-B-Y-based multicomponent alloys designed using a cluster line approach. Cluster lines Fe8B3-Y, Fe8B2-Y, Fe83B17-Y, Fe6B-Y and Fe9B-Y intersect with cluster line Fe12Y-B at five compositions in the Fe-B-Y phase diagram that are taken as basic compositions. Further minor alloying by additions of 2 at.% Nb and 2 at.% M (M=Ti, Hf, Ta, Mo, Ni, and Sn) was designed and alloy rods were synthesized with a diameter of 3mm by suction-casting in copper mold. A. Considering mass loss of B and Y during arc melting, the ingots were all weighted after each melting and the final compositions were revised accordingly. When M=Ti, Hf, Ta and Mo, the quinary alloys form BMGs at compositions close to the Fe8B3-Y cluster line. This signifies that the close-packed Archimedes octahedral antiprism Fe8B3 is the basic atomic cluster that favors glass formation. The best glass-forming composition is (Fe69.9B24.6Y5.5)96Nb2Ti2 with Tg=944K, Tx=997K, Trg=0.666. When M=Ni and Sn, no glass formation was observed.
