摘要	The glass formation and the local structure of the rapidly cooled Pd55Ni45 alloy melt under high pressures are simulated by using molecular-dynamics method. The results show that pressure makes the critical cooling rates for glass formation reduce obviously. With the increase of pressure, the microstructure of the Pd55Ni45 Melt consisted mainly of a more compacted local structure with perfect icosahedra, which may be the main evidence for the contribution of the high pressure to the glass formation.
