| Summary: | In recent years, the interest on solid-state recycling of aluminum chips increases over
the years due to the less energy consumption of the process. This research studies the
quantitative effects of preheating temperature and volume fraction of Zirconium
Dioxide when it is reinforced to the Aluminum alloy AA6061 on its mechanical
properties. The parameters of the experiment are preheating temperature and volume
fraction of ZrO . Temperature are varied between 450 and 550 ℃ according to the
boundary parameters. The volume fraction of ZrO consists of 5, 10 and 15% of the
reinforcement. Increasing the volume fraction of ZrO correlates with the increase of
mechanical and physical properties. Design of Experimental with factorial design was
implemented to analyse the magnitude of response on the mechanical properties from
the variable of parameters. The preheating temperature was revealed to be the most
significant factor affecting the yield strength and the microhardness of the composite
followed by the volume fraction of ZrO . It is revealed that the most optimum
temperature is 550 ℃ and the optimum percentage of volume fraction is 9.28%. Both highest microhardness and yield strength were obtained from these optimum
temperatures. Scanning Electron Microscope (SEM) revealed on how elongation in
Zirconia chips is affected by the amount of ZrO reinforcement. Energy Dispersive
Spectroscopy (EDS) analysis performed revealed on the arbitrary weight out of total
weight for every element in the composite such as Al, Zr, O and Si. |
