| Abstract: | Magnesium alloy is the lightest structural metallic materials, which has low density and high strength, high stiffness ratio and high shock absorption. It is known as the green metallic structural materials in the 21st century. La , which is an important alloying element in metallurgy , plays an unique role in these fields, such as purification of molten alloy, refinement of microstructure, improvement of mechanical properties and corrosion resistance, and so on. Effects of La on microstructure, mechanical properties and corrosion resistance of magnesium alloys are summarized. |
