Efficient temperature dependence of parameters for thermo-mechanical finite element modeling of alloy 230

Abstract Nickel-based alloys are often selected for manufacturing components operating in extreme conditions such as high-temperature thermo-mechanical cyclic loadings because of their good corrosion and high temperature resistance. This is, instance, the case solar receivers where material undergoes daily cycles going from ambient to approximately 700 °C. To predict behavior under this type complex loadings, advanced numerical models – Chaboche-type required. In addition model, a complete representation dependency is essential both stability physical accuracy which obtained with parameters assuring certain continuity over studied range temperature. end, new formulation proposed Alloy 230 anisothermal isothermal loadings.
