| Abstract Scope |
As the development of new materials continues to flourish, knowledge of microstructural interactions is key to producing stronger and safer mechanical components. In this paper, in-situ high resolution DIC performed conjointly with EBSD is employed on pure nickel samples of various grain sizes to investigate interactions between geometrically necessary dislocations and grain boundaries, particularly in their relation to the shear bands which develop. Critical attributes, such as misorientation angle and slip system data, are fed into machine learning algorithms to confirm their correlations and demonstrate the influence of short- and long-range internal stresses on predicting macroscopic properties. The result is a model that improves the current understanding of material behaviors and can accurately predict their macroscopic properties using only microstructural information. |
