%X The microstructures of the Mg65Cu25Y10 alloy solidified under pressures of 2-5 GPa and ambient pressure have been investigated by X-ray diffraction, differential scanning calorimetry and transmission electron microscopy. Experimental results show that the pressure has a great influence on the phase microstructure during solidification process. High pressure leads to the favorable precipitation of nanoscale Cu2(Y, Mg) phase, which is a metastable phase and transforms to stable Mg2(Cu, Y) phase after annealing. The mechanism for the effect of the pressure on the grain size during solidification process of Mg65Cu25Y10 alloy has been discussed.
