An outer ring of 29320 self-aliging roller bearing was used in an experimental study on the casting of Zr₄₁Ti₁₄Cu_12.5Ni₁₀Be_22.5 amorphous alloy. Numerical simulations of mold filling and solidification processes were carried out to determine the velocity fields and temperature fields of the alloy melt during mold filling process as well as the temperature fields and temperature gradient fields in the course of the solidification. According to the results, a cast with a complete shape can be obtained at 1200 °C under the condition that the cooling rate is greater than the critical cooling rate.The ring-shaped part with a thickness of 25 mm, an equivalent diameter of 22 mm, and a mass of 1.32 kg was prepared by gravity casting in a copper mold. X-ray diffraction and differential scanning calorimetry data revealed that the produced cast had the amorphous structure.
