Refinement of Mg₂Si Particulate Reinforced Al-20%Mg₂Si In Situ Composite with Addition of Antimony

Abstract:

Al-Mg₂Si in-situ composite have received wider attention due to their improved properties which mark them as attractive candidate to manufacture most of automotive and aerospace components. Result show that the melt treatment of the in-situ composite by addition of antimony caused to refining the morphology of primary Mg₂Si reinforcement which would expect to improve the mechanical properties. Effect of Sb on the characteristics parameters of Mg₂Si particles have been investigated by thermal and microstructural analysis. The result has revealed that addition of 0.8 wt.% Sb produced optimum refinement effect on the morphology as coarse structure has been changed to polygon one. The result also showed depression with nucleation temperature, T_N and growth temperature, T_G which also correspond to the refinement effect.
