Effect of Zirconium on Mechanical Behavior of Aluminum7075

Metal matrix composites (MMCs) are rapid increase in research and becoming attractive materials for advanced aerospace applications because their properties can be tailored through the addition of selected reinforcements. The addition of reinforcement materials like metals or ceramics into metal matrix improves its mechanical properties like tensile, hardness and fatigue compared to other conventional materials. In this work Zirconium is used as reinforcement in Al 7075 and metal matrix composites are prepared by using stir casting process. In this four specimens are considered (100 % Al, 99 %Al+1 %Zr, 98 %Al+2 %Zr, 97 %Al+3 %Zr) for finding the tensile strength and hardness properties. The tensile strength of the specimens is to be carried out on MCS60 UTE 60. The Hardness test is to be carried on Vickers Hardness tester for finding the Hardness property.
