We have studied the amorphization behavior of Mg85-xY 15Cux (x=20~40) alloy powders synthesized by high energy ball milling technique. The as-milled powders were mainly amorphous after 1 0 hours of milling. The thermal stability o f these Mg85-xYi 15Cux glassy powders was investigated by differential scanning calorimeter (DSC). The ranges of Tg ,Tx and ΔTX are around 430-459K, 467-497K, and 30-46K, respectively. Mg61Y15Cu24bulk metallic glass with nanocrystalline precipitates homogeneously embedded in a highly dense glassy matrix was successfully prepared by vacuum hot pressing. It was found that the applied pressure during consolidation could enhance the thermal stability and prolong the existence of amorphous phase inside Mg61Y 15Cu24 powders.
