Aging of γ′ Precipitates at 750 °C in the Nickel-Based Superalloy AD730<sup>TM</sup>: a Thermally or Thermo-Mechanically Controlled Process?

Aging of γ′ Precipitates at 750 °C in the Nickel-Based Superalloy AD730<sup>TM</sup>: a Thermally or Thermo-Mechanically Controlled Process?

The microstructural stability during aging at 750 &#176;C of the &#947;/&#947;&#8242; nickel-based superalloy AD730<sup>TM</sup> 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...
