Effect of Nickel and Chromium Addition on the Microstructure and Mechanical Properties of Aluminium - 4% Zinc Alloy

Authors(3) :-W. C. Okafor, J. U. Odo, E. E. Nnuka

This work studied the effect of microalloying on the microstructure and mechanical properties of Al. 4%Zn alloy. The mechanical properties studied were yield and ultimate tensile strength, % elongation, compressive strength and hardness. The tests were conducted using the ASTM E8, E10 and E20 standards. Microstructural analysis was done using metallurgical microscope model Olympus PMA-3 and the micrographs were obtained with an attached camera. The results obtained showed that nickel and chromium modified the structure of the studied alloy and therefore improved the mechanical properties.
