• Qualification of AM parts: Extreme value statistics applied to tomographic measurements (2017, background): “CT scans are usually adopted for monitoring the quality of 3Dprinted parts and to correlate it to the resulting material properties [5,7,10,12,13,32,33].”
• Additive Manufacturing Processes: Selective Laser Melting, Electron Beam Melting and Binder Jetting—Selection Guidelines (2017, background): “On the other hand, processes like EBM use a hot bed (>870 K) and hence do not produce a fine microstructure like the SLM process [1,31,32].”
• Analyzing the effects of powder and post-processing on porosity and properties of electron beam melted Ti-6Al-4V (2017, background): “Therefore, if the goal is to retain the fine microstructure characteristic of as-built AM parts, then one must also perform a high-temperature β-solution heat treatment followed by a quench [6].”
• Anisotropy and heterogeneity of microstructure and mechanical properties in metal additive manufacturing: A critical review (2018, background): “A study on EBM-built Ti-6Al-4V however reported a decrease in fracture toughness after heat treatment processes, which was due to the coarsening of the microstructure [23].”
• Fatigue of additive manufactured Ti-6Al-4V, Part I: The effects of powder feedstock, manufacturing, and post-process conditions on the resulting microstructure and defects (2020, methodology): “To stay above the detection limits and not perceiving noise as defects usually a threshold of 8 voxels per volume for the smallest defect is used in analysis software, therefore, typical commercial machines lack sufficient resolution for pores with diameters less than 10 μm [87,88].”
