000015429 520__ $$2eng$$aTurbine blades are used in the hottest part of the aero-engines and are made of Ni-based single-crystal superalloys chosen for their exceptional mechanical performances at high temperatures. However, at high temperature/low stress conditions, Ni-based single crystal superalloys are subjected to  ...  microstructural evolution influences the mechanical behavior and the damage. When subjected to multiaxial state of stresses, the microstructure is highly convoluted and has to be modeled in order to improve the mechanical response and lifetime prediction. A 3D  ...  is therefore expressed and compared with a high-temperature creep test performed on a bi-notched specimen developing multiaxial stress/strain fields. The 3D microstructural model is providing good performances and can be then used for improving the mechanical and lifetime prediction of turbine blades experiencing multiaxial state of stresses due to their complex geometry.
