The PIP procedure (https://doi.org/10.1002/adem.202100437) is now a mainstream mechanical test. Products are available in which indentation, profilometry and data processing are all automated and take about 3 minutes. It allows stress-strain curves to be obtained for relatively small volumes of material, such that local properties can be mapped where they are changing over short distances. It has been used to measure local property variations in the vicinity of welds (https://doi.org/10.1002/adem.202101645). It can also be used to detect and characterize anisotropy, for example in AM superalloy components (https://doi.org/10.2139/ssrn.3746800). In the current work, PIP is applied to a relatively large and complex AM component, in which the growth conditions, and hence the mechanical properties, vary with location during production. It is shown that these consequent variations can be detected and characterized on a scale of a few mm. The procedure has also been applied to study the anisotropy developed in this component.
