Experimental research on mechanical, material, and metallurgical properties of Inconel 600: Application in elevated temperature environment

Abstract

Du to high strength and toughness, high oxidation resistance, and high ductility, the Inconel 600 alloy is an ideal choice for the components used in combined heat and power turbines. Therefore, in this paper, the authors conducted experimental tests to better underestand the mechanical behavior of superalloys Inconel 600. The experiments included tensile, fatigue, and creep tests. The material deformation and stress-strain behavior were measured. In addition the yield strength, ultimate tensile strength, elongation, and modulus of elasticity were captured. By illustrating the engineering and true stress-strain curves the Ramberg-Osgood relation were extracted. As a result of fatigue test, the relationship between strain amplitude and the number of cycles to failure for specimens were obtained. The creep tests were conducted at a constant temperature of 650℃. The strain-time data were collected, and the resulting creep strain-time curve were plotted for smooth samples under their respective stress conditions.   REFERENCES G. Becerra, M.R.B.
