Abstract
Microstructures and mechanical properties of Mg-8Li-1Al-xCe alloys are studied. Results show that Mg-8Li-1Al-xCe alloys are composed of α phase (white), β (gray) and AlCe phase. The grains are refined with Ce added in Mg-8Li-1Al alloy. The grains of Mg-8Li-1Al-1.4Ce alloy are refined most obviously. AlCe compound that forms in alloys is favorable for the improvement of strength when the content of Ce is less than 0.6 %. The as-cast Mg-8Li-1Al-0.6Ce alloy possesses the peak values of tensile strength and elongation (173.11 MPa and 21.2 %, respectively). The as-cast Mg-8Li-1Al-1.0Ce alloy possesses the highest Brinell hardness (61.8 HB).

Key words
