Microstructural response and strain hardening in deep cold rolled nickel-based superalloy for aerospace application by Kumar, Dharmesh, Idapalapati, Sridhar, Wei, Wang

“…After DCR process, a deep layer of compressive residual stress up to 1mm was observed, which agrees well with the depth profile of Vickers micro-hardness. Statistical analysis of Grain Orientation Spread (GOS) in the Electron Back Scattered Diffraction (EBSD) map also shows the presence of strain hardening layer after the DCR process. …”
