title = "Statistical assessment of fatigue-initiating microstructural features in a polycrystalline disk alloy",
abstract = "Fatigue is the life limiting property of polycrystalline nickel-base superalloys used for turbine disks. Fatigue cracks in Ren{\'e} 88DT frequently initiate in large grains that are in the tail of the size distribution and contain favorably oriented annealing twin boundaries. High resolution three dimensional volumes of Ren{\'e} 88DT have been collected via TriBeam tomography for analysis of grain structure and twin boundaries. Most twin boundaries were found to be highly coherent, allowing twin boundary inclination to be calculated using orientation measurements collected from two dimensional cross sections. This insight enables identification of fatigue initiating microstructural features in large two dimensional scans, providing initiation site statistics for a significant number of boundaries.",
