The Influence Of Rare Earth Addition On Cast Magnesium Alloy

The application of Magnesium Alloy has been rapidly developed since 1950s when rare earth metals were used as alloying addictives. The addition of rare earth metals in magnesium alloys greatly improves the creep resistance, the strength properties both at room temperatures and elevated temperatures and the castability of Magnesium Alloy.Influence of RareEarth Additives (La, Sm and Dy) on the Microstructure and Dielectric Properties of Doped BaTiO3 may also influence the microstructural evolution and ferroelectric properties [16,17]. The purpose of this paper is a comparative investigation of the microstructure and.
