Effects of Ce-rich RE additions and heat treatment on the microstructure and tensile properties of Mg-Li-Al-Zn-based alloy

▶ Adding Ce-rich RE leads to the formation of Al2RE/Al3RE phases in LAZ532 alloy. ▶ Ce-rich RE additions improve the tensile properties of the alloy. ▶ The tensile properties of alloys processed by heat treatment are increased greatly. ▶ Adding RE changes the fracture pattern of the alloy.
