| 英文摘要 | Al85Ni5Y8CO2 has the highest glass forming ability in Al-based amorphous alloys to date. To locate the optimum composition in its basic system is of great importance for preparing Al-based bulk metallic glass. Al-Co-Y system has not been studied thoroughly as yet. In this work, it is indicated that Al88CO5Y7 is the best alloy and its critical thickness is up to 230 mu m. The glass forming ability shows a strong dependence on composition in this system. Surprisingly, there is no obvious glass transition phenomenon upon heating in the best glass formation alloy. Compared with T-rg and Delta T-x criteria, phase selection method is proved to be effective to locate the optimum alloy and characterize the glass forming ability dependence on composition in this system. fcc-Al, Al3Y and Al9CO2 are the competing phases with amorphous phase during its formation. |
