Adding Mg and Si elements to aluminum alloys can produce solid soluble conditions or second-phase metal compounds [3-7].
The increase in strength and hardness of AlMgSi alloys is due to substantial soluble strengthening and second-phase strengthening.
Most Aluminum alloys contain Silicon, so adding Magnesium is required to obtain the hardening effect of Mg2Si. [16,18].

Intermetallic compounds are innovative materials and are far superior to conventional metals and alloys.
These intermetallic compounds have a great potential in industrial and technological fields because most of the intermetallic compounds are stronger as well asstiffer at elevated temperature and provide far better corrosion resistance than conventional metals and alloys.Over the past few years the scientific interest in the study of these intermetallic compounds emanates greatly because of their high-tech applications.
Some RM intermetallic compounds have been found to be highly ductile and thus has moved the horizon of fracture toughness and other mechanical properties of the intermetallic compounds is under crucial investigation.
