The effect of defect population on the anisotropic fatigue resistance of AlSi10Mg alloy fabricated by laser powder bed fusion

Metallurgical defects have a critical influence on the anisotropic fatigue resistance of additively manufactured parts under cyclic loading. Here X-ray computed tomography (CT) has been used to characterise the defect population for laser powder bed fusion processed AlSi10Mg alloy and correlated with the tensile and high cycle fatigue (HCF) properties of specimens loaded both parallel and perpendicular to build direction. Despite similar tensile...
