Low-cycle fatigue behavior of as-cast and heat-treated Haynes 25 superalloy under varying strain amplitudes

Cobalt-based superalloys are extensively used in high-temperature cyclic environments, yet their fatigue life is often constrained by microstructural instability and dislocation motion. In Haynes 25, controlling precipitate formation through proper heat treatments is critical to improving fatigue re...
