| Abstract Scope |
A microstructure informatics approach based on EBSD and EDS data was used to quantitatively describe the sequence of microstructural changes occurring during consolidation and processing of an advanced powder metallurgy (PM) Ni-based superalloy. Starting with the consolidated powder compact (HIP microstructure), microstructural features such as primary γʹ precipitate size, retained plastic strain, and various subsets of grains (pure γʹ, mixed γ/ γʹ and pure γ grains) were tracked as a function of processing. Changes that occurred due to the conversion to billet and isothermal forging processes were systematically quantified to better understand the sequence of recrystallization mechanisms that cause changes in the microstructure from thermomechanical processing. Quantitative assessment of the microstructure metrics provides new insight into mechanisms operative during thermomechanical deformation. Results from the study will be presented and the microstructural evolution will be rationalized. |
