Near-surface residual stress distributions in the Ti6Al4V substrate resulting from EBAM of a 50 mm BH Ti6Al4V wall structure with and without SR, as determined through incremental hole-drilling measurements. It is noteworthy that the residual stress data for depths of 0-0.1 mm have compression effects from machining. (a) As-deposited. (b) SRed. (c) As-deposited. (d) SRed.
