Zusammenfassung:Y-containing Al-Li-Cu-Mg-Zr based alloy is made up by adding rare-earth element Y in Al-Li-Cu-Mg-Zr alloy, and may be made into sheet or rod material through such steps as calcining in vacuum induction furnace, refining and casting under protection of argon, high-temp. treatment, and shaping by extrusion. Its advantages are high plasticity, strong antioxidation property and good high-temp. performance, so adapting to aeronautics and astronautics engineering.
