Purpose: The paper presents a crystallization process of Ni68,7Cr6,6Fe2,65Si7,8B14C0,25 metallic glasses. The Ni68,7Cr6,6Fe2,65Si7,8B14C0,25 metallic glasses were produced by the CBMS method for two different conditions of the casting, with different cooling rate. Design/methodology/approach: The crystallization of Ni68,7Cr6,6Fe2,65Si7,8B14C0,25 metallic glasses by methods of electrical resistance measurements (ERM), differential thermal analysis (DTA), and transmission electron microscopy (TEM) was studied. Findings: The investigation has shown, that the conditions of vitrification (different, but higher than critical cooling rate) influence different course elementary crystallization processes during thermal activation. Research limitations/implications: The differences in temperature of beginning of elementary crystallization processes of alloy, as a function of thickness of strip was disclosed. Practical implications: The electrical resistance measurements method (ERM) can be used for analysis of thermal stability of metallic glasses. Originality/value: The paper presents, that the conditions of vitrification influence different course elementary crystallization processes during thermal activation.
