In collaboration with the University of Limerick, this case study investigates the suitability of PIP testing to explore the detection of property variations in parts produced through additive manufacturing.

The objective in this study, conducted in collaboration with The Welding Institute, was to determine if PIP testing could accurately map the stress-strain behaviour across a weld with a fine spatial resolution, and to quantify the time and cost savings that PIP offers over traditional tensile testing when used for characterising weld mechanical properties.

The aim of this case study, conducted in conjunction with Ovako, was to use PIP testing to characterise a case-hardened layer by indenting planar surfaces after progressive removal of thin surface layers.

In this case study, conducted in collaboration with Professor Roger Reed and Dr. Tony Tang from the University of Oxford, we assess whether PIP testing can be used to measure stress-strain curves on small alloy samples made by additive manufacturing.

This investigation relates to two types of sample supplied by Energy Densification Systems. These were both a shaped component of Hardox steel, with and without a cermet insert brazed into it. Via PIP testing it was possible to obtain stress-strain relationships for local areas of the component. The heat treatment associated with the brazing process (which was not revealed to PLX) induced significant changes in the stress/strain responses of all locations.

In this study we use PIP testing to spatially map the variations in mechanical properties across a large forged aluminum component.
