Effects of segmented thermal-vibration stress relief process on residual stresses, mechanical properties and microstructures of large 2219 Al alloy rings

•A STVSR process was proposed to stress relief for large 2219 Al-Cu alloy transition rings.•The residual stresses decreased and mechanical properties improved after STVSR.•The underlying mechanisms of residual stress relief by STVSR were quantitatively revealed.•The residual stress relief is attribu...
