Effect of amorphous silica by rice husk ash on physical properties and microstructures of recycled aluminium chip AA7075

High strength to weight ratio of aluminium reinforced as metal matrix composites is a well known material used in automotive application. The effects of recycled aluminium chips AA7075 with amorphous silica by rice husk ash on the physical properties and microstructure were investigated. Recycled al...
