The Effect of Lanthanum Addition on the Microstructure and Mechanical Properties of A390 Aluminium Alloy

Aluminium alloys are widely used in the industries and for biomedical applications, because when compared with other materials they provide a high strength-to-weight ratio, better wear resistance, less density, and low coefficient of thermal expansion. However, these alloys possess some limitations...
