摘　　要：Melt of Nd60Cu20NiloAl10 alloy is solidified by rapid compression from 0.1 to 5.5 GPa at 793K and from 0.1 to 3.2GPa at 873K within 20ms, separately. A fully bulk metallic glass is obtained by the rapid compression method. By comparing with as-cast bulk metallic glass （BMG）, it is found that Nd60Cu20Ni10Al10 BMG prepared by rapid compression exhibits a higher thermodynamic stability and a paramagnetic property. The relationship between the glass-formation temperature and the pressure in rapid compression for the BMG is demonstrated in the P - T phase diagram.Melt of Nd60Cu20NiloAl10 alloy is solidified by rapid compression from 0.1 to 5.5 GPa at 793K and from 0.1 to 3.2GPa at 873K within 20ms, separately.
