Purpose: The aim of the present work is characterization of the centrifugal casting method, apparatus and produced amorphous materials, which are also known as bulk metallic glasses. Design/methodology/approach: The studied centrifugal casting system consists of two main parts: casting apparatus and injection system of molten alloy. The described centrifugal casting method was presented by preparing a casting apparatus "CentriCast - 5". The apparatus includes a cylindrical copper mold, which is rotated by a motor. The transmission allows to changing the speed of rotating mold. Findings: Bulk metallic glasses are a novel class of engineering materials, which exhibit excelent mechanical, thermal, magnetic and corrosion properties. Centrifugal casting is a useful method to produce bulk amorphous materials in form of rings, tubes or cylindrical parts. Presented centrifugal casting method and casting apparatus has been prepared to fabricate the samples of bulk metallic glass in form of rings with an outer diameter of 25 mm and controlled thicknesses by changing the weight of the molten alloy. Research limitations/implications: Studied centrifugal casting method and casting apparatus has been prepared to fabricate the samples of bulk metallic glass. For future research a characterization of microstructure and properties of prepared material will be performed. Practical implications: The centrifugal casting is a useful process to produce bulk amorphous materials in form of rings, tubes or graded amorphous matrix composites. It seems to be a very simple method, which allows to obtain BMG materials. Originality/value: The centrifugal casting method allows to produce bulk amorphous rings with thickness above 1-mm.
