Evaluation of uniaxial tensile property of high-temperature alloy GH3536 based on indentation method
The nickel-based high-temperature alloy GH3536 is widely used in high-temperature core equipment in energy and chemical industries,such as high-temperature gas-cooled reactors,petrochemical equipment,and various energy conversion devices due to its excellent oxidation resistance and corrosion resistance and good creep strength.The forging and additive manufacturing GH3536 are taken as the research objects,and the feasibility of applying the Wang-Zhang fitting coefficient model to the spherical indentation tests(SITs)to realize the uniaxial tensile property inversion of GH3536 is explored.The results indicate that the yield strength of GH3536 produced using two different manufacturing processes is in good agreement with the results of conventional tensile tests.However,there is some deviation in the prediction of tensile strength,but the error and result stability can also basically meet the engineering application requirements.It can provide an important technical means for the online evaluation of material degradation of high-temperature components,which is helpful to ensure the service safety of high-temperature core equipment in related energy and chemical industries.
