    Communicating Materials Systems Knowledge through Processing-Structure-Properties-Performance (PSPP) Maps
    ( 2018-01) Goulding, Ashley N. ; Leung, Jonathan F.W. ; Neu, Richard W.
    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.

    The Development of a Process-Structure-Properties-Performance (PSPP) Map for Aluminum-Zinc-Magnesium-Copper Alloys Used in Aircraft Applications
    (ASM International, 2016-04) Goulding, Ashley N. ; Neu, Richard W. ; Sanders, T.H. Jr
    In 2011, the White House announced the Materials Genome Initiative, which aims to cut down the cost and time required to discover, develop, and optimize a material and deploy it in a commercial system. One method of achieving this is by integrating experimental test methods, computational tools, and known knowledge databases. While the potential for computational models to speed and assist process-structure-property optimization is not a new concept, one of the key issues in the implementation of models in this space is the lack of a standard method of communication regarding the physical and chemical mechanisms that drive a materials system, and the amount and type of data required to accurately characterize that materials system in its entirety. This work focuses on developing process-structure-property-performance (PSPP) maps as this missing standard communication method. Here we detail the steps that should be taken to generate a map for any system, and then briefly discuss how those steps were applied to high-strength Al-Zn-Mg- Cu alloys. These alloys are highly utilized in aircraft applications and are extremely complicated and commercially viable materials which are repeatedly subject to re-optimization, and are thus a good example of the value of these maps and how they can be used.
