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, for instance, the case for solar receivers where the material undergoes daily cycles going from ambient temperature to approximately 700 degrees C. To predict the material behavior under this type of complex loadings, advanced numerical models - such as Chaboche-type models - are required. In addition to the model, a complete representation of the temperature dependency of the material is essential for both numerical stability and physical accuracy of the model, which is obtained with parameters assuring a certain continuity over the studied range of temperature. To this end, a new formulation for the temperature dependency of material parameters in Chaboche-type models is proposed for the Alloy 230 under both anisothermal and isothermal cyclic loadings.
