摘要：

The shape samples of Mg65Cu25Y10-xNdx(x=0, 2, 4, 6, 8, 10) were made by copper mold suction casting with commercial raw material under condition of no vacuum melting. By differential scanning calorimetry (DSC) and X-ray diffractometry, the effect of Nd on glass forming ability of Mg-Cu-Y-Nd was analyzed. The results show that the samples with x of 0, 4 and 6 are bulk metallic glass, and the best glass forming ability (GFA) appears at x=4, while the reduced glass transition temperature Trg is 0.592 and the supercooled liquid region ΔTx is 66 K. However, samples with x of 2, 8, 10 obviously deviate from eutectic points, their glass forming ability decrease and the samples mainly consist of crystalline and a few non-crystals.
