Dataset to the publication Fatigue crack propagation in functionally graded bi-material steel obtained through wire-arc additive manufacturing

Dataset to the publication Fatigue crack propagation in functionally graded bi-material steel obtained through wire-arc additive manufacturing. The dataset includes the data obtained from fatigue characterization and post-mortem analysis of the specimens tested from a bi-metal additively-manufactured parent specimen. The dataset includes:ABAQUS FEM analysis results, including CAE model data with mesh, supports, loads and assembly conditionsElectron back-scatter diffraction (EBSD) data, including crystallographic maps and project datasets, as well as MTEX matlab code used to identify martensite variants from Focused Ion Beam-milled specimens examined under Transmission Kikuchi Diffraction (TKD). Fatigue crack growth rate measurements, obtained from sub-size SENB specimens under constant force, constant \Delta K, and under load sheading schemes to obtain K_TH values.
