Abstract

In the present study, our aim is to develop a deeper understanding of strain accumulation in the vicinity of grain boundaries (GBs) within a polycrystalline aggregate. We focus on the role of slip transmission in the uniaxial plastic deformation of a nickel-based superalloy, Hastelloy-X. Utilizing high resolution ex-situ digital image correlation (DIC) and electron backscatter diffraction (EBSD), we establish the most likely dislocation reactions due to slip transmission and use this information to calculate the residual Burgers vector and plastic strain magnitudes across each interface. From our analysis, we quantitatively show an influence of the magnitude of the residual Burgers vector on plastic strains across GBs.
