solute atoms are seen on the elastic properties of Mg-X dilute alloys. The solute atom that influences the elastic properties of Mg by a large factor is K, while the minimum influence is seen when Al is added to Mg. Addition of s-block elements to Mg results in a lower bulk modulus than the addition of p- and d-block elements. While an apparent. In order to improve significantly the mechanical properties of the magnesium alloy, all the castings for cars and bikes are subjected to solution heat-treatments. Al–7Si alloys are extensively used in aerospace and automotive industries due to their excellent formability, high corrosion resistance, and good comprehensive mechanical properties [1,2].The A and A alloys are two representative Al–7Si alloys with Mg contents ranging from to wt.% [2,3,4].They are heat-treatable casting alloys, which can be strengthened by the precipitation Cited by: 2.   These alloys are widely available at moderate costs and their mechanical properties are good up to 95 to oC. The second group consists of magnesium alloyed with various elements (rare earth, zinc, thorium, silver etc) except aluminum, all containing a small but effective zirconium content that imparts a fine grain structure and thus improved.
