摘　　要：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.The glass formation was investigated in the melt-spun Al-rich Al-Co-Y alloys by the microstructure evolution.
