Purpose: The purpose of this paper is to present of influence of heat treatment on the changes of structure, ductility, mechanical properties and particularly fracture morphology of the amorphous NANOPERM ribbons. The alloy was obtained in ribbons form by melt spinning method. Design/methodology/approach: The following experimental techniques were used: scanning electron microscopy (SEM) and X-ray diffraction (XRD) phase analysis method to test the structure. The measurement of mechanical properties, like: tensile strength Rm, ductility ε were made. Tensile tests were performed on testing machine INSTRON 1195. Plastic properties of investigated ribbons were determined in bending test. Findings: Morphology of fractures obtained after decohesion process in tensile test shows the history of amorphous alloys crystallization. Practical implications: The relationship between heat treatments parameters, structure and mechanical properties can be useful for practical application of these alloys. Originality/value: The temperature ranges of structure and mechanical properties changes after heat treatment of NANOPERM alloys it has been determined.
