The study of spatial distribution of mechanical properties in a "thick" amorphous wire of Co-alloy 84KHSR has been carried out. A cone sample of amorphous wire of variable diameter (70–300 μm) was obtained by the Ulitovsky-Taylor method by varying the drawing speed during the wire production process. After removing the glass sheath and checking for the conformity of the wire structure to the amorphous state, the mechanical properties of the cone wire samples with diameters of 100 and 270 μm were studied by the instrumental indentation method. It was found that amorphous wire in the range of diameters 70–300 μm retains stable values of hardness and modulus of elasticity in cross and longitudinal sections. Mechanical properties of wires of the studied diameters also practically do not change when moving from the center of the samples to the edge. The obtained data indicate high isotropy of the amorphous structure of the wire of variable diameter. The noted higher values of hardness and modulus of elasticity in the 270 µm diameter sample (Н = 9,8 GPa, Е = 212 GPa) compared to the 100 µm diameter sample (Н = 8,6 GPa, Е = 163 GPa) may be due to a more intensive formation of the cluster structure due to a decrease in the effective cooling rate of the "thicker" wire. It was noted that such wires may find application in the manufacture of new types of medical instruments.
