Mechanical properties of silicon nitride fortified aluminium based metal matrix composites – A review

Aluminum
metal matrix composites (AMMCs) are in potential demand in numerous field such as automotive, defence
and sports recreation sectors owe to important properties compared to traditional
aluminium alloys. AA7055 is
generally embraced and it is the ideal composite between Al7XXX series arrangement mainly used for different vehicle
applications. AA7055 metal matrix composites properties can be improved by incorporating suitable reinforcement. The motivation behind this assessment is to give an outline of silicon nitride in the AA7055 MMC as a base material and to clarify changes in mechanical properties due to the nclusion of reinforcements that can be further improved in combination with the addition of appropriate reinforcement materials to the base matrix.
