FABRICATION AND ANALYSIS OF ALUMINIUM FLYASH WITH TUNGSTEN CARBIDE BY POWDER METALLURGY

The ever-increasing demand for light weight, economy and environmental purpose has leadto the development of advanced materials. MMCs are widely used in industries, as they have excellent mechanical properties and wear resistance.So, in this project introduced Particulate-reinforced hybrid composites because of it is cost less than fiber-reinforced composites owing to the lower cost of fibers and manufacturing cost. In addition to improved physical and mechanical properties, particulate-reinforced hybrid composites are generally isotropic and they can be processed through conventional methods used for metals. Thus, the fly ashes, aluminum AL7075, tungsten carbide reinforced with aluminum composites are increasingly used as substitute materials for high temperature applications.This project deals with the selection of better material for the process of more hardness and temperature resistance, in that Aluminum hybrid composite are produced by AL 7075 as matrix material and fly ash and tungsten carbide as reinforcement in different composition.(Al- 96, tungsten carbide - 2, Fly ash- 2)Different sample are produced by using stir casting methods. Various tests have been conducted to evaluate the different properties of aluminum composites and they are compared with commercial aluminum alloy.
