• Effects of building orientation and heat treatment on fatigue behavior of selective laser melted 17-4 PH stainless steel (2017, background): “Therefore, multiple cracks initiated in AM parts can readily progress and coalesce into a single fracture plane [33].”
• 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, background): “Under cyclic loading, pores and LOF defects can overshadow any effects of microstructure, substantially degrading the fatigue life by serving as crack initiation sites (CIS) [22,34–36].”
• Fatigue of additive manufactured Ti-6Al-4V, Part II: The relationship between microstructure, material cyclic properties, and component performance (2020, neutral): “…life and Crack Initiation Site (CIS) fractography were reported for both powder feed AM (laser and electron beam) and traditionally fabricated wrought materials [11,12,14,15,17 – 20 , 50 – 59 ] The CIS was estimated from the root of the projected area of the defect in the direction of loading.”
• Additive manufacturing of metallic components – Process, structure and properties (2018, background): “[558], who studied the DED-L of Ti-6Al-4V, concluded that large pores close to the surface and with irregular or sharpe features had the most negative impact on fatigue performance.”
• Metal additive manufacturing in the commercial aviation industry: A review (2019, background): “Although AM processes are capable to produce high-density products above 99%, micro-cracks or porosity could still exist and could affect fatigue behavior in service [145, 146].”
