| It is known that cooling rate from the liquid state is an important factor for producing the bulk metallic glasses. However, almost no other factors such as electric and/or magnetic fields were investigated. The present authors have reported that the glass-forming ability of Mg-Cu-Y and Fe-Co-B-Si-Nb alloys is enhanced with increasing the electromagnetic vibration force. This study aims to investigate effect of the frequency of the electromagnetic vibrations on glass forming ability in Fe-Co-B-Si-Nb bulk metallic glasses. As a result, it was found that the electromagnetic vibrations affect the increase in the cooling rate and the decrease in the number of crystal nuclei directly. |
