Climate changes of recent decades forced engineers and scientists to challenge themselves with new solutions and improving existing ones. In this scenario heavy-duty gas-turbines (GTs) development was focused on improving performances, e.g. augmenting power-output and efficiency, and employing them as a support to renewable energy sources (RES). As a consequence, GTs components have to withstand always higher thermomechanical loads. Moreover, nowadays GTs are operated in cyclic conditions much more frequently than in the past. Turbine blades are surely one of the most critical components due to the harsh operating conditions. Hence, the production process of these components is a critical aspect to be considered in design and qualification phase.
