In recent years, Far Field HEDM experiments have been used to understand different micromechanical behavior in crystalline materials. The experiments are capable of characterizing individual grain level information (position, elastic strain and orientations) with great accuracy. Current research has been motivated by observation of orientation gradient in diffraction pattern during plastic deformation. The orientation gradient indicates the bending (curvature) of crystal lattices that can be correlated to the plastic strain in the grain scale. This work characterizes in-situ plastic strain using results from HEDM experiments performed in 301L SS at CHESS using the curvature information.
