In-situ x-ray computed tomography analysis of fracture mechanisms in ultrasonic additively manufactured Al-6061 alloy
The deformation and failure mechanisms in an ultrasonic additively manufactured Al-6061 alloy are studied using in-situ x-ray computed tomography during tensile deformation as well as ex-situ characterization with scanning electron microscopy. The role of pre-existing voids between the build layers on the failure mechanism is discussed with a focus on individual foil failures and void coalescence.
