Martensitic stainless steels are very attractive alloys, widely used because of their outstanding corrosion-resistance and high strength properties. These steels are considered for high temperature applications, mainly in power generation plants and fusion reactors technology. In service, all these alloys will be subjected to complex thermo-mechanical cyclic loading. Such loading can be simulated by isothermal strain-controlled fatigue experiments. Concerning fatigue investigations, one of the most interesting aspects to consider is the mechanisms of deformation and accumulation of damage leading to material failure.
