玻璃形成在融化旋转被调查由微观结构进化的 Al 富有的 Al-Co-Y 合金。有 230 亩 m 的厚度的以前的 Al88Co5Y7 被发现的最好的玻璃,和它形成能力(GFA ) 的玻璃比以前报导的 Al88Co4Y8 合金的高。这结果显示 GFA 对在系统的合金作文强烈敏感。阶段选择方法是定位最佳玻璃形成作文而非 T_ 和三角洲 T_x 参数(rg ) 的一个有效方法。
The glass formation was investigated in the melt-spun Al-rich Al-Co-Y alloys by the microstructure evolution. The best glass former Al88Co5Y7 with the thickness of 230μm was found, and its glass forming ability (GFA) was higher than that of previously reported Al88Co4Y8 alloy. This result indicates that GFA is strongly sensitive to the alloy composition in the system. The phase selection method is an effective way to locate the optimum glass formation composition rather than Trg and △Tx parameters.
