Using of taguchi method to optimize the casting of Al–Si Al2O3 composites

Abstract EN

Taguchi method is a problem–solving tool which can improve the performance of the product, process design and system.

This method combines the experimental and analytical concepts to determine the most influential parameter on the result response for the significant improvement in the overall performance.

In this research Al–Si / Al2O3 composites was prepared by vortex technique using three different parameters, stirring time, stirring speed, and volume fraction of the reinforcement particles.

A tensile and hardness tests were done for the resulted castings.

The primary objective is to use Taguchi method for predicting the better parameters that give the highest tensile strength and hardness to the castings, and then preparing composites at these parameters and comparing them with the randomly used once.

The experimental and analytical results showed that the Taguchi method was successful in predicting the parameters that give the highest properties and the volume fraction was the most influential parameter on the tensile strength and hardness results of castings.
