为形成能力( GFA )和 Mg65Cu25-xAlxGd10 的机械性质的玻璃上的 Cu 的艾尔的部分替换的效果( x=0 , 1 , 3 和 5 ,臼齿的部分,%)合金被X光检查 diffractometry ( XRD )学习,微分扫描热量测定( DSC )和单轴的压缩测试。结果表明合金的 GFA 随着从 0 ~ 3 增加 x 稍微变化,然后突然地减少, x 增加直到 5。粘性能被艾尔极大地与 Cu 的适当替换改进(3% ,臼齿的部分) 在 Mg65Cu25Gd10 体积,金属性的玻璃,和结果的破裂力量,到失败的全部的紧张,和塑料紧张是 898 MPa, 2.19% 和 0.2% 分别地。
The effect of partial substitution of Al for Cu on the glass forming ability(GFA) and mechanical properties of Mg65Cu25-xAlxGd10 (x=0, 1, 3 and 5, molar fraction, %) alloys were studied by X-ray diffi-actometry(XRD), differential scanning calorimetry(DSC) and uniaxial compression test. The result reveals that GFA of the alloys changes slightly with increasing x from 0 to 3, and then abruptly decreases with x increasing up to 5. The plasticity can be greatly improved with appropriate substitution of Cu by A1 (3%, molar fraction) in Mg65Cu25Gd10 bulk metallic glass, and the resultant fracture strength, total strain to failure, and plastic strain are 898 MPa, 2.19% and 0.2%, respectively.
