Abstract
In the present investigation silicon dioxide of varying weight proportion was added in to AZ91D magnesium alloy matrix and its microstructure and mechanical properties was characterized for functional applications. Optical microscope is used to analyzed its microstructure studies and its performance measures was characterized using ASTM standards. From the experimentation it was observed that it has good wettability between the matrix and reinforcement and also it was found that the ceramic strengthening particulates are uniformly distributed through the cross section of matrix alloy. The increase in hardness and tensile strength can be attributed to the presence of hard reinforcement in a AZ91D alloy matrix, which absorbs the load and restricts dislocation movement due to the difference in thermal expansion coefficients between matrix and reinforcing particulates. On the other hand, the increase in percentage of reinforcement in matrix minimizes the ductility and reducing the percentage of elongation between the intermixture The compressive strength increased due to uniform dispersion of silicon dioxide on magnesium alloy and the presence of interface reaction of Mg2Si between the immixture. Owing to the inclusion of silicon dioxide that the formation of Mg17Al12 phase reduced and hence improvement in corrosion resistance of synthesized composites was observed.
