Design and Development of Hybrid Stir Casting Process

Abstract

The widespread adoption of particulate metal matrix composites (MMCs) for engineering applications has been hindered by the high cost of producing components of complex shape. Casting technology may be the key to overcoming this problem with stir casting. But the problem arises with stir casting is wettability and porosity. To overcome the problem of porosity a hybrid casting process is needed. So, hybrid stir casting process was developed to produce a silicon carbide particulate aluminum alloy composite. In this paper, the authors have discussed the various parts like Muffle Furnace, Thermocouple, Electric motor Impeller & Stirrer, Crucible, Vacuum pump, Nitrogen gas, and Lifting mechanism of the Hybrid Stir Casting process.
