Aging-Induced Residual Stress Relaxation in Laser Powder Bed Fusion CM247LC Superalloy Parts Quantified by Neutron-Diffraction-Validated Eigenstrain Tomography

This dataset provides the complete three-dimensional full-field reconstructions of residual stress and eigenstrain for a CM247LC superalloy component fabricated via Laser Powder Bed Fusion (LPBF), both in its as-printed and aging-treated (900 °C for 8 h) states. The data were generated using a mechanics-informed Eigenstrain Tomography framework validated by independent neutron diffraction measurements.

The provided ZIP file contains high-resolution volumetric data in .vtu (VTK Unstructured Grid) format, which can be visualized and post-processed using open-source software such as ParaView. The datasets explicitly include the following tensor and scalar fields:

- Eigenstrain (Eig.pvd)
- Residual Elastic Strain (ElasticStrain.pvd)
- Residual Stress (Stress.pvd)
- Total Strain (TotalStrain.pvd)
- Displacement (U.pvd)
- von Mises Stress (VonMises.pvd)

This repository aims to support total transparency in additive manufacturing process qualification and to provide a benchmark for researchers developing predictive simulations of thermal stress relief in nickel-based superalloys.
