Purpose: The paper presents the changes of mechanical properties and the fractures of Co70.5Fe2.5Mn2Mo1Si9B15 metallic glass ribbons after a low-temperature activation process. Design/methodology/approach: The studied alloy was fabricated by continuous casting of the alloy stream on a turning wheel. The plastic properties were determined using the bend test. The investigations of unit cracking energy using the “tearing” test on the testing machine were carried out. The structure testing in transmission electron microscope and the static tensile test on the Instron testing machine were also carried out. Findings: The studies for 5 samples and for 2 ribbon sides were carried out. The highest plasticity occurred after annealing at 200°C for 1 h. The differences of mechanical properties in a function of a cross section of the ribbon were also presented. Practical implications: Despite the occurrence of heterogeneity of properties on the thickness of metallic glass ribbon the essential meaning have the averaging properties of a product which decided about possibility of practical application. Originality/value: In the article there was found that studied samples obtain different plasticity and different value of the yield point in the different bending methods.
