A small punch test (SPT) investigation of additively manufactured (AM) AlSi10Mg was performed using small disc samples (about 200Ám thickness and 3mm diameter). Effects of different aspects unique to AM materials and SPT were investigated and analyzed, such as microstructure, sample thickness and sample direction.
The microstructures and bulk mechanical properties following different heat treatments were characterized using microscopy methods and tensile tests. SPT samples were then prepared from the bulk material. For comparison, 6xxx aluminum alloy samples were also tested by SPT.
The results show that the unique AM microstructure does have an effect on the measured mechanical properties when using small samples, compared to bulk samples. Aspects that normally do not require attention when testing wrought aluminum alloys do need to be taken into account when performing SPT on AM aluminum. This conclusion and the effects of the different parameters investigated will be discussed in the presentation.
