Abstract: This paper presents some results for numerical simulation of the thermal field developed during rapid cooling of iron base alloy (Fe₇₃Cr₂Ga₄P₁₃Si₅C₃), to obtain bulk metallic glasses. Technology of rapid cooling gives the possibility to obtain bulk metallic alloys with an amorphous structure which can be used for industrial applications like magnetic shields. Validity of the numerical model of the cooling process was confirmed by the X-ray diffraction analysis. Once the model being validate, it can be used to optimize the rapid cooling process and casting mold geometry to be able to investigate the possibility to obtain larger amorphous bulk components.
