Effect of Heat treatment and Cryogenic treatment on Mechanical Properties and Microstructure of Aluminum Alloy 356 Reinforced with Silicon Carbide

Abstract

Metal matrix composites are gaining widespread acceptance in recent times due to its importance of application in the field of automobile, aerospace, agriculture farm machinery and many other industrial application, because of its essential properties such as high strength, low density, wear and corrosion resistance which are not available in single conventional material. the wide use of particular metal matrix for engineering application has been obstructed by the exact use of silicon carbide(Sic) by weight % , hence high cost of components .The present study deals with the addition of reinforcement such as silicon carbide to aluminum in various proportion. Each reinforcement properties which when added enhances the property of aluminum alloy. Improvement of mixture metal network composites has turned into a significant zone of research enthusiasm for material science, this paper manages assessing mechanical properties of aluminum fortified with various Development of hybrid metal matrix composites of silicon carbide (4%,6%,8%,10%) combination .stir casting method was used for fabrication of aluminum metal matrix composites. To investigate the properties of AlSic for varied % of silicon carbide under heat treatment and cryogenic treatment, test like –tensile test, hardness test, corrosion test were conducted. The result obtained indicates the properties of AlSic were quite beneficial according to the requirements.
