Role of defects in fatigue damage mechanisms of cast polycrystalline superalloy MAR-M 247

High-cycle fatigue life of nickel-based superalloy MAR-M 247 was experimentally determined for as-cast material and material processed by hot isostatic pressing (HIP). Fatigue testing was conducted at temperatures 650, 800, 900 ∘C in laboratory air. HIP was done at the following conditions: 1200 ∘C/...
