Study on the Reinforcement of Aluminum Alloy A356 Using SiC Particles by Mechanical Stirring

Abstract:

This paper is to research the manufacturing process of A356 alloy matrix composites reinforced by SiC particles by mechanical stirring and how the size of particles ,volume fraction affect mechanical property has been studied , too. The text results revealed that larger particles especially particle size larger than 30um were suitable using this technique, meanwhile, it will hard to adding particles into the alloy when particle lower than 20um size. The effects of SiC particle addition on the hardness properties of A356 alloy and with higher volume fraction particles lead to greater hardness.
