Purpose: The goal of this work was to investigate the influence of chemical composition and isothermal heating in order to determine the change of the mechanical properties of the metallic ribbons by depth sensing indentation technique. Design/methodology/approach: The amorphous metallic ribbons were manufactured by planar-flow-casting method. Instrumented hardness measuring was carried out using the nanohardness tester DUH-202 with a Vickers indenter. Observations of the structure of powders were made on the OPTON DSM-940 scanning electron microscope. The diffraction examinations and examinations of thin foils were made on the JEOL JEM 3010 transmission electron microscope. Findings: The analysis of the mechanical properties and structure of the Co-based amorphous ribbons obtained in the by planar-flow-casting process proved that the no significant differences between both ternary alloys in local mechanical properties HM, EIT and W were observed for amorphous state but differences between ternary and multicomponent alloys were observed. In heat treated state small differences between materials were observed too. Research limitations/implications: For the metallic Co-based amorphous ribbons, further mechanical examinations and structure are planed. Practical implications: 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 mechanical properties, whose dimensions and shape can be freely formed. Originality/value: The paper presents influence of annealing temperature and chemical composition of metallic ribbons on martens hardness, indentation modulus EIT, work for deformation and ratio of elastic and total indentation energy. Heating of ribbons obtained by melt spinning technique, to check its effect on changes of mechanical properties. Results and a discussion of the influence of annealing temperature microhardness metallic ribbons is presented.
