英文摘要	Ultrafine-grained Al90.4Y4.4Ni4.3Co0.9 was synthesized by powder metallurgy from partially-amorphous powder precursors. A good combination of mechanical properties was obtained by optimizing size and density of second phases. The resultant alloy shows high specific strength and specific modulus as well as a tensile ductility of similar to 5% at room temperature. Particularly, this alloy exhibits good mechanical stability at elevated temperature, which is superior to most high-temperature aluminum alloys. These results provide evidence for the effectiveness of Al-based metallic glasses as precursors for the development of high-temperature aluminum alloys. (C) 2020 Elsevier B.V. All rights reserved.
