Abstract
Recently, the automotive industry has replaced cast iron to lightweight materials like aluminum for engine efficiency of automobiles and an emission control by government. In this paper we studied two auto parts manufacturing methods using an alloy of A356. That is gravity casting and H-NCM Rheo-diecasting forging. We analyzed the microstructure and mechanical properties for this method. In Microstructure analysis results, H-NCM Rheo-diecasting forging has more finer microstrucre and better forging effect. Resulting in better mechanical properties than gravity forging.
