Grain Boundary Engineering (GBE) and GBE surface treatments (GBEST) are patent- and trademark-protected thermo-mechanical processing technologies that are applicable to a broad range of metals and alloys. The main objective of this study was to extend the applicability of the GBE processing technologies to a more advanced superalloy, Allvac718Plus, which is a new derivative of Alloy 718. The specific technical objectives of the study were to: (1) develop and optimize GBE processing strategies for the bulk microstructure of the 718Plus and (2) develop a processing methodology for locally optimizing the GBE microstructural characteristics at the near-surface region of the alloy. In this paper, the microstructural characteristics achieved from the GBE processing of the 718Plus alloy are presented. The effect of the GBE processing on the high temperature mechanical properties of the 718Plus alloy is presented in a separate paper in this symposium proceedings.
