Influence of cerium content on the microstructure and thermal expansion properties of suction cast Al-Cu-Fe alloys

Low-expansion alloys are of great importance and can be used for the development of new aerospace materials. Herein, we report diverse rare earth quasicrystal alloys fabricated by the vacuum suction casting process. The effects of the addition of cerium (Ce) on the microstructure, thermal expansion...
