To light metal alloys (Al-Si-Cu-Ni-Mg) additional proportions of zirconium (Zr) investigation of the effects on microstructural ana mechanical properties

In this study we have done to improve the structural and mechanical properties of aluminum alloys, which provide use in many areas; We aimed to obtain a stronger material by adding zirconium at different rates to the Al alloy, which is a ductile material.The fact that the zirconium element can be added as an alloying element by providing a hardening to an alloy material, increasing its strength, providing a perfect harmony in the bond structures, contributing to the increase of the melting temperature, will be a reference model in facilitating human life as a result of the use of this element in different sectors.In our thesis, aluminum-based Si-Cu-Ni-Mg reinforced alloy material is pressed in powder metallurgy with the reinforcement of Zirconium (Zr) element at different rates and poured by vacuum arc grinding method (provided that there are 4 different samples, the first is 81% Al, 12% Si, 4% Cu, 2% Ni, 1% Mg), (second is 80% Al, 12% Si, 4% Cu, 2% Ni, 1% Mg, 1% Zr), (third is 79.5% Al, 12% Si, 4% Cu, 2% Ni, 1% Mg, 1.5% Zr), (fourth is 79% Al, 12% Si, 4% Cu, 2% Ni, 1% Mg, 2% Zr) on the microstructure and mechanical properties of the formed Al-Si-Cu-Ni-Mg-Zr alloy was investigated.
