Defects as a root cause of fatigue weakening of additively manufactured AlSi10Mg components

[Display omitted] •Fatigue strength was found insensitive to the build relative to scraper direction.•Fatigue strength is highly sensitive to porosity morphology, size and distribution.•In most cases, lack of fusion was the killer defect. Additive manufacturing is an emerging technique that is not o...
