Investigation of Hardness by Experimental and Simulation Studies on Al-12.5% Si Piston Alloys Reinforced by Cu Powder

摘要

In this work, Aluminum composite was fabricated by using friction stir squeeze casting. Copper powder of size 5μm was stirred and later squeezed with molten Al-12.5% Si with a weight percentage ranging from 2 to 10% of the former. Hardness values from the experiments were measured and later used to determine the relationship between input parameter and output. Hardness measured was found to be good at 6% of copper. A mathematical model was developed by using Bezier equation. Neural network model was developed for further simulation. The results were predicted by using both the equation and by using neural network were on par with experimental values obtained.
