Purpose: The paper presents a structural, thermal and magnetic characterization of Co-based amorphous samples in as-cast state and after annealing process. Design/methodology/approach: The studies were performed on Co70Fe5Si15B10 metallic glass in form of ribbons with different thickness. The amorphous structure and phase analysis of studied samples after annealing process was examined by X-ray diffraction...
Purpose: The paper presents a structure characterization, thermal and soft magnetic properties analysis of Fe-based bulk amorphous materials in as-cast state and after crystallization process. In addition, the paper gives some brief review about achieving, formation and structure of bulk metallic glasses as a special group of amorphous materials. Design/methodology/approach: The studies were performed...
Purpose: The paper presents a structural relaxation and crystallization process of Ni68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses. The Ni68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses were produced by the CBMS method for two different conditions of casting at different cooling rate. Design/methodology/approach: The relaxation and crystallization of Ni68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses by...
Purpose: The paper presents a structure characterization, thermal and soft magnetic properties of Fe-based bulk amorphous materials in as-cast state and after crystallization process. Design/methodology/approach: The studies were performed on Fe72B20Si4Nb4 metallic glass in form of ribbons and rods. The amorphous structure of tested samples was examined by X-ray diffraction (XRD), transmission electron...
Purpose: The paper presents a crystallization process of Fe-based amorphous materials. The aim of work is presentation of the influence of annealing temperature on structural changes and magnetic properties of Fe72B20Si4Nb4 metallic glasses. Design/methodology/approach: The studies were performed on metallic glasses as ribbons. Crystallization behaviour of the studied alloy was examined by differential...
Purpose: The paper presents a crystallization process of i68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses. The Ni68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses was produced by the CBMS method with cooling rate corresponding for amorphous structure manufacturing. Design/methodology/approach: The crystallization of Ni68.7Cr6.6Fe2.65Si7.8B14C0.25 metallic glasses by method internal friction (IF) differential...
