摘要

The wire arc additive manufacturing (WAAM) deposition of Ti–6Al–4V (Ti64) and Ti–6Al–2Sn–2Zr–2Mo–2Cr (Ti62222) alloys produce long columnar grains, indicating tensile anisotropy in various directions. Therefore, this study applied interlayer peening (ILP) during WAAM to modify the solidification morphology. The index of plane anisotropy (IPA) of the as-built Ti64 deposit was 30
