The Use of PIP Testing to Characterise Additively Manufactured Superalloys

Additive Manufacturing AM is an attractive procedure for many metals, including Ni-based superalloys. Mechanical characterization of these materials is challenging, due to anisotropy and the cumbersome nature of existing testing methods. Professor Roger Reed and Dr. Yuanbo Tang will review recent advances at The University of Oxford on the production and characterization of such materials.

Professor Bill Clyne and Dr. Jimmy Campbell will demonstrate a new method, Profilometry-based Indentation Plastometry (PIP) that is ideally suited to characterizing these materials. Stress-strain curves are obtained via iterative FEM simulation of the indentation process, converging on optimal plasticity parameter values. It will be shown that, for isotropic materials, indentation data can be generated and processed in less than 3 minutes on the PLX bench-top PIP device, to obtain tensile (nominal) stress-strain plots that agree closely with conventional uniaxial testing.
