Purpose: This paper tends to present the thermal analysis and structure of selected Fe-based bulk metallic glasses for welding processes. Design/methodology/approach: The studies were performed on Fe-Co-B-Si-Nb alloy in form of plate and rod. Master alloy ingot with compositions of Fe37.44Co34.56B19.2Si4.8Nb4 was prepared by induction melting of pure Fe, Co, B, Si and Nb elements in argon atmosphere. The investigated material was cast in form of plate with thickness 0.5 mm and rod with diameter 3 mm. The structure analysis of the studied materials in as-cast state was carried out using X-ray diffraction (XRD). The thermal properties: glass transition temperature (Tg), onset crystallization temperature (Tx) and peak crystallization temperature (Tp) of the as-cast alloys were examined by differential scanning calorimetry (DSC) and melting temperature (Tm), liquidus temperature (Tl) by differential thermal analysis (DTA) methods. The parameters of glass forming ability included reduced glass transition temperature (Trg), supercooled liquid region (ΔTx), α, β, y, δ and stability (S) were calculated. Findings: The Fe-based bulk metallic glasses in form of plate and rod with good glass forming ability were produced by die pressure casting method. The investigation methods revealed that the studied as-cast bulk metallic glasses were amorphous. These materials exhibit good glass-forming ability. The calculated GFA parameters indicated that the slightly best glass-forming ability has Fe37.44Co34.56B19.2Si4.8Nb4 alloy in form of rod. It is confirmed that these parameters could be used to determine glass forming ability of tested amorphous alloy for welding processes. Research limitations/implications: It is difficult to obtain a bulk metallic glasses in form of plate and rod with large sizes. Various empirical parameters have been proposed to specify the glass forming ability of bulk metallic glasses. Several GFA indicators have been determined by measuring the characteristic thermal parameters. A few simple criteria were calculated to explain the GFA of tested alloys. Practical implications: These obtained values of GFA parameters can suggest that studied alloys are suitable materials for further practical application at welding process. Originality/value: The success formation and investigation of the casted Fe-based bulk metallic glasses. The chemical composition of Fe37.44Co34.56B19.2Si4.8Nb4 alloy were tested first time.
