Testo completoIn view of the turbine entry temperature evolution, the main challenge for metallurgists is to elaborate new alloys able to withstand higher temperatures while keeping great mechanical properties. Therefore, knowing the relationships between microstructural parameters and mechanical properties at high temperatures (700°C and more) is mandatory.The creep and dwell-fatigue durability as well as the damage mechanisms of AD730™, a new nickel base superalloy developed for turbine disks, have been analyzed. Several microstructural parameters were studied (grain boundaries, grain size, size and distribution of γ′ precipitates) as well as experimental parameters (temperature, environment, applied stress or dwell period). By using single crystalline specimens having the same chemical composition of the studied alloy, it has been shown unambiguously that single crystalline microstructures do not necessarily present better creep properties compared to polycristalline ones. This result is supposed to be caused by a grain boundary strengthening mechanism. Moreover, in creep at 700°C, it has been shown that the main viscoplasticity controlling parameters are the size and distribution of γ′ precipitates.An unexpected dwell-fatigue behavior has been observed for long hold times and in a specific applied stress window. This phenomena is attributed to a “Bauschinger type” effect, occurring during unloading phases

Testo completoNickel-based superalloys possess exceptional mechanical properties and corrosion resistance at high temperature. These mechanical properties result partly from the hardening precipitation of Ni3Nb γ″ or Ni3(Al, Ti) γ′ phases. The objective of this PhD is to better understand how forming operations of industrial parts may influence this precipitation. Two superalloys have been studied in this PhD : Inconel® 625 alloy formed a room temperature and reinforced by the γ″ phase, and AD730™ alloy hot forged and reinforced by the γ′ phase. Thermal treatments, mechanical and thermomechanical tests have been performedin order to, on the one hand, reproduce the plastic strain levels and/or the grain structure obtained at the end of industrial forming operations, and on the other hand to trigger the precipitation or the evolution of already existing precipitates. The microstructures have then been quantitatively characterizedby scanning electron microscopy regarding the grains structure, the dislocationsorganization and the precipitation state.In the Inconel® 625 alloy, the nucleation of γ″ precipitates during a thermal treatment at 650 °C is not influenced by a strain applied before, supporting the relevancy of the 650 °C temperature to bring an homogeneous hardening to industrial parts. In the AD730™ alloy, the γ′ precipitation during a cooling after a hot compression takes place sooner in unrecrystallized grains than in recrystallized grains, by elastic relaxation when nucleating. Concomitantly, the recrystallization front dissolves these γ′ precipitates present in unrecrystallized grains to avoid any incoherent γ/γ′ interface. Then γ′ precipitates reprecipitate on the recrystallization front with a coherent γ/γ′ interface in recrystallized grains, and can afterwards subdivide to reduce the global elastic energy. This PhD includes the development of specific tools : reduction of the measurement noise of EBSD maps for a more accurate assessmentof geometrically necessary dislocations densities, image analysis and precipitation model
