Purpose: The main aim of the paper was investigation of influence of geometry of rapid solidified rods on properties (structure, fracture morphology, microhardness) of Fe36Co36B19Si5Nb4 alloy. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), scanning electron microscopy (SEM), light microscopy (LM), X-ray diffraction (XRD) method, Vickers microhardness. Findings: Changes of mechanical properties (microhardness) and different fracture morphology of rapidly solidified rods were presented. Research limitations/implications: Obtained structures are depended on cooling rate and glass forming ability of the alloy. Practical implications: The rapidly solidified bulk alloys have been commercialized in magnetic application and high strength materials. Originality/value: Diverse fracture morphology as well as changes of microhardness in amorphous regions of differently relaxated rate are observed.
