Highly processable Mg65Cu25Tb10 bulk metallic glass

Mg65Cu25Tb10 alloy was cast into glassy rod of 5-mm in diameter in air and argon atmosphere by normal copper mold casting method. The glass-forming ability, ignition and oxygen resistances of the alloy were investigated by X-ray diffraction, differential scanning calorimeter and acoustic measurement. The glass-forming alloy is fund to show high ignition and oxygen resistances due to the Tb addition. The beneficial effects of Tb on the glass-forming ability and ignition resistance are discussed.
