MECHANICAL PROPERTIES OF ALUMINIUM 6061 CENOSPHERE COMPOSITES
Keywords:
Aluminium 6061, fly ash cenospheres, density, porosity, tensile strength, ductilityAbstract
Aluminium based metal matrix composites (MMC) are being considered as good candidates for replacing conventional alloys in many industries such as aerospace, automotive, and sport due to their potential engineered properties. They can be tailored to have superior properties such as high specific strength and stiffness, increased wear resistance, enhanced high temperature performance better thermal and mechanical fatigue and creep resistance than those of monolithic alloys. In the light of the above, the paper focusses on development and characterization of aluminiun Cenosphere composite and evaluate its properties such as hardness, density, porosity and its tensileproperties. It is observed that the density, porosity and ductility decrease with an increase in the percentage of reinforcement and a considerable increase in hardness and tensile strength.
