Abstract
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
