Abstract

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 a new method for producing Mg-Cu-Y bulk metallic glasses by using electromagnetic vibrations is effective in forming the metallic glass phase. However, effects of the electromagnetic vibrations on glass-forming ability in other alloy systems are not investigated. Thus, this study aims to investigate effects of the electromagnetic vibrations on glass-forming ability in Fe-Co-B-Si-Nb bulk metallic glasses. As a result, it was found that glass-forming ability of Fe-Co-B-Si-Nb alloys also enhances with increasing the electromagnetic vibration force. Moreover, the electromagnetic vibrations were found to affect the increase of the cooling rate and the decrease in the number of crystal nuclei directly, but not to affect the crystal growing rate.
