The creep of high pressure turbine blades is a critical issue for the certification of a helicopter turboshaftengine. Due to their excellent mechanical properties at high temperatures, nickel-based single crystalsuperalloys are widely used for the manufacturing of these blades. For these components, certificationrequirements include non-isothermal conditions based on the mixing of different operating conditions (cruise,take-off …), conditions much more damaging than standard isothermal conditions used conventionally inlaboratories.The aim of this thesis is to get a better prediction of the mechanical behavior and creep life of thesematerials during certification procedure of helicopter turboshaft engines under which creep is the main lifeli...
