EN Purpose: The aim of the work is to investigate the structure and magnetic properties of the cobalt based hot pressed Co68Fe4Mo1Si13.5B13.5 powder obtained in high-energy ball milling process. Design/methodology/approach: The nanocrystalline ferromagnetic powders were manufactured by high-energy ball milling of metallic glasses ribbons in as state. The hot pressing process was made on machine "Degussa". Observations of the structure of die stampings were made on the OPTON DSM-940 scanning electron microscope. Graphical analyses of the obtained X-ray diffraction patterns, as well as of the HC=f(TA) relationship were made using the MICROCAL ORIGIN 6.0 program. Findings: The analysis of the magnetic properties and structure of the die stamping out that compared to the magnetic properties of the amorphous ribbons as their precursor, that hot pressing process deteriorates their magnetically soft properties. Research limitations/implications: For the metallic Co-based amorphous ribbons, further mechanical and structure examinations are planed. Practical implications: Structure and magnetic properties analysis of die stampings of powdered amorphous metallic ribbons is helpful to prepare this material by laboratory methods. Feature an alternative to commercial alloys and composite materials are the amorphous and nanocrystalline metal amorphous ribbons obtained by melt spinning technique and make it possible to obtain the new composite materials with best magnetic properties, which dimensions and shape can be freely formed. Originality/value: The paper presents influence of hot pressing parameters process of metallic powdered ribbons on structure and magnetic properties of obtained die stampings.
