Abstract :
Aluminum metal matrix composites have wide spread applications in the field of aerospace, automobile and
defence due to its superior mechanical properties like ultimate strength and hardness. AMCs possess better
tribological properties too. This research work aims to synthesis aluminum metal matrix composites through stir
casting route. The matrix material chosen was AA7050 and reinforcement material chosen was ZrSiO4. The
compositions namely AA7050+2.5ZrSiO4, AA7050+5%ZrSiO4, AA7050+7.5%ZrSiO4, AA7050+10%ZrSiO4,
AA7050+12.5%ZrSiO4 and AA7070+15%ZrSiO4. From the microstructure examination it was observed that when
increasing the reinforcement weight percentage significant changes in the microstructure was occurred and
homogenous distribution between the matrix and reinforcement material was take place. The microstructure
assessment of various composites were carried out by using scanning electron microscope and stated.
