| Abstract Scope |
Ni-based superalloys are used in complex parts such as turbine blades where their form must be optimized for mechanical strength, temperature regulation, as well as aerodynamic efficiency. The complex form leads to the development of complex multiaxial stress states. The effect of this stress triaxiality on isothermal creep has been studied before. However, conditions during real-world application are seldom isothermal. In this project, we explore the effect of thermal jumps on the multiaxial creep behavior in Ni-based single-crystal superalloys. Crystal plasticity modeling is used to further understand the experimental results. |
