Purpose: The main aims of this work is the presentation of the influence of yttrium addition on the structure and properties of BMG and the production attempt of chosen Fe-based bulk metallic alloys. Design/methodology/approach: The studies were carried out on Fe- based alloys ingots with the following compositions Fe43Co7Cr15Mo14C15B6, Fe41Co7Cr15Mo14C15B6Y2 and Fe39Co7Cr15Mo14C15B6Y4. Samples were prepared by induction melting of the pure Fe, Co, Cr, Mo, C, B and Y elements in argon atmosphere. The structure was tested with X-ray diffraction. In order to investigate the structure scanning electron microscopy was used. The thermal properties of the alloys were examined by DTA and DSC methods. Findings: Bulk metallic glasses with yttrium addition exhibit high glass forming ability. These materials depending on accurate chemical composition present excellent corrosion resistance, magnetic, electric and mechanical properties. Fe-based materials with yttrium addition are potential materials for industrial applications. Research limitations/implications: It is very difficult to obtain a metallic glass of Fe43Co7Cr15Mo14C15B6, Fe41Co7Cr15Mo14C15B6Y2 and Fe39Co7Cr15Mo14C15B6Y4 alloys. All tested alloys have crystalline structure. Taking into account all the factors affecting the test samples, we can conclude that the received samples have not an amorphous structure for the non-uniform distribution of yttrium in materials. Originality/value: Overall presentation of the yttrium addition influence, the formation and the study of Fe-Co-Cr-Mo-C-B-Y bulk metallic materials.
