In this study. three news compositions of multicomponent Fe–Co–Nb–B–Y bulk metallic glasses (BMGs) were developed by using commercial raw materials (Fe–Nb and Fe–B) and suction casting process. The fully glassy cylindrical samples (∅ = 3. 0 mm) were reached for Fe63Co7Nb4B23Y3 and Fe52Co18Nb4B23Y3 (at. https://pipingrockers.shop/product-category/kale/
