Defect inspection technologies for additive manufacturing (2021, background): “The Glenn Research Center of NASA uses the penetration method to inspect the surface of key components of liquid propellant rocket engines manufactured by SLM and EBM processes.”
A comparison of fatigue strength sensitivity to defects for materials manufactured by AM or traditional processes (2017, neutral): “Most of these techniques utilize a powder bed, which is melted by a laser [8–10,62,63,67,68,76–78] or electron beam [11,68,69,78], whereas some others consider direct metal deposition in the form of wire [11,69,71].”
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): “Various representations of the probability distribution functions have been used throughout literature to evaluate the distribution of defects in AM parts [93,94].”
Fatigue of additive manufactured Ti-6Al-4V, Part II: The relationship between microstructure, material cyclic properties, and component performance (2020, background): “This type of failure has been reported in HIPed AM Ti-6Al-4V samples [54], where the propensity for cracks to initiate from defects has been decreased.”
Improved fatigue strength of additively manufactured Ti6Al4V by surface post processing (2020, background): “Fatigue testing has shown that both L-PBF and E-PBF Ti6Al4V subjected to hot isostatic pressing (HIP) followed by traditional machining can achieve fatigue properties similar to conventional wrought Ti6Al4V [4 – 6].”
