Combined effect of surface anomalies and volumetric defects on fatigue assessment of AlSi7Mg fabricated via laser powder bed fusion

In recent years, the fabrication of aluminum alloy parts via laser powder bed fusion has been extensively considered in the biomedical, aerospace, and other industrial sectors, as it provides advantages such as the ability to manufacture complex shapes with high performance associated with lightweight design. However, surface irregularities and sub-surface defects limit the full exploitation of such parts in fatigue-critical applications....
