چکیده انگلیسی
Localized plastic deformation and hardening was studied in laser shock peened (LSP) Inconel 718 SPF (Super plastic forming), a fine grained Ni-Base superalloy, using electron backscatter diffraction (EBSD), nanoindentation, and micro pillar compression testing. 718SPF samples were LSP-treated with two different laser power densities. After LSP, the plastic deformation is manifested as increase in the fraction of low angle misorientations and the formation of sub-grain boundaries. EBSD was used to study plastic deformation as a function of distance from the peened surface for different laser intensities. Different approaches like image quality mapping and local misorientations analysis were used to study the in-depth distribution of the plastic strain. Results show that EBSD is effective in the qualitative characterization of localized plastic strain of the materials subjected to LSP.
