Purpose: In the present paper an equipment applied in thermal conductivity measurements of metallic glasses was described. Design/methodology/approach: The paper describes the design solution of a measuring station, components, and idea of measurements of thermal conductivity. In order to correct measurement the calibration of presented equipment was realized. It was realized by determination of power losses and resistance of contacts. Methods of thermal conductivity measurements were also described in theoretical description. Findings: The suggested method of thermal conductivity measurement allows to avoid a procedure of solving complicated equations. The developed measuring station enables measurements of thermal conductivity of bulk metallic glasses in form of rod with diameter 3 mm. Research limitations/implications: The relationship between the thermal conductivity and the diameter of metallic glass samples is an interesting issue. In the future the authors are going to test rods with another diameters (not only 3 mm). Practical implications: The thermal conductivity of metallic glasses is necessary to calculate cooling rates during the fabrication of bulk metallic glasses. That are very important properties. These properties are indispensable for example in a computer simulation of a solidification process. Originality/value: Up to now there is very poor knowledge about thermal conductivity measurements of metallic glasses. There is not many references about this matter. There is no information about the thermal conductivity dependence on samples dimensions of metallic glasses.
