Aging of γ′ Precipitates at 750 °C in the Nickel-Based Superalloy AD730TM: a Thermally or Thermo-Mechanically Controlled Process?
Autor: Nicolas Mrozowski, Gilbert Hénaff, Florence Hamon, Anne-Laure Rouffié, Jean-Michel Franchet, Jonathan Cormier, Patrick Villechaise
Publikováno v: Metals, Vol 10, Iss 4, p 426 (2020)
The microstructural stability during aging at 750 °C of the γ/γ′ nickel-based superalloy AD730TM is investigated in this work. Strain-free aging and aging during fatigue tests are conducted, with a focus on the influence of the strain ratio, the

Impact des carbures sur la variabilité des propriétés en fatigue de superalliages pour disques
Autor: Govaere, Adèle
Publikováno v: Autre. ISAE-ENSMA Ecole Nationale Supérieure de Mécanique et d'Aérotechique-Poitiers, 2020. Français. ⟨NNT : 2020ESMA0020⟩
Nowadays, original engine makers are challenged by the environmental requirements imposing drastic decrease of CO2 and NOx emissions. It leads to the development of γ/γ′ nickel-based superalloys to ensure good tensile and fatigue properties and a
