DETECT - Defect dEtection and impact on faiTgue behavior for mEtal AM parts with Complex geomeTries

Quality control of internal defects is to date the main bottleneck for industrialization of high performance AM parts. Moreover, there are no general acceptance of which internal AM defects that can be tolerated from a fatigue point of view and there is therefore a need to establish defect thresholds that can be used as acceptance criteria for each AM material.

The overall scope of the project: determine the threshold (in form of maximum size, shape and position/zone) for when internal AM defects affect the fatigue performance using conventional NDT equipment like computed tomography, ultrasonic and liquid penetrant as well as data from in-process control.

A PhD Student at Linköping University, focusing to about 4/5 on material science and fatigue, and some 1/5 on X-ray-based NDT for PBF. The main supervisor will be at Linköping University and University West will co-supervise the student in the NDT field.
