Communicating Materials Systems Knowledge through Processing-Structure-Properties-Performance (PSPP) Maps

Abstract

Knowledge about the behavior of a specific materials system is concisely summarized in a Processing-Structure-Properties-Performance (PSPP) map. This is a useful tool that can effectively serve as a standard method of communication regarding the physical and chemical mechanisms that control the performance of a materials system, and gives guidance on the type of data required to accurately characterize that materials system in its entirety. This article describes a workflow to generate a map for any materials system, and then applies these steps to develop a map for Ni-base superalloy synthesized by additive manufacturing.
