Abstract: | In recent years, lighter components with better mechanical properties and newlinestrength are preferred in automotive, aerospace and related manufacturing newlineindustries to meet the design requirements. The choice of a lighter material in a newlineparticular application is governed by various factors which determine the newlineperformance metric of the product. Nickel based super alloys have excellent newlinemechanical properties and hence they are used for several industrial newlineapplications. Inconel 718 alloys are a nickel-based (Ni-Cr-Fe) austenite (and#947;) alloy newlinewhich has superior properties such as high corrosion resistance, high strength newlineand high level of oxidation resistance. It is mainly used in nuclear reactors, newlineaircrafts, jet engines, gas turbines and power generation applications. newline Inconel 718 alloy components are manufactured using various newlinemanufacturing process. Deep drawing is one of the most important manufacturing newlineprocesses used for manufacturing components in nuclear and aerospace newlineindustries. The process of sheet metal forming is mostly used in various newlineindustries to deform the material into the desired shape and size. The traditional newlinedeep drawing of Inconel 718 alloy is hard at room temperature due to its limited newlinework efficiency and very high strength when compared with the various alloys newlinesuch as aluminium, and steel. In this process, parameters play a crucial role in newlinedetermining the geometrical accuracy and quality of cup. newlineThis work initially focused on the uniaxial tensile test and the material newlineproperties of Inconel 718 alloy sheet in the longitudinal, diagonal, and transverse newlinerolling directions. The mechanical properties such as percentage of elongation, newlinenormal and planar anisotropy, strain hardening exponent, strength coefficient, newlineyield and ultimate tensile strength were determined. newline |
