Effect of deep cold rolling on residual stress distributions between the treated and untreated regions Ti–6Al–4V alloy

The residual stress distributions caused by the deep cold rolling (DCR) process, with a focus on the distributions at the boundary of the treatment zone, are examined in this study. A three-dimensional finite-element (FE) model, validated with experimental residual stress data, is used to study the...

It is shown that the net material movement causes larger plastic deformation in the boundary zone between the burnished and unburnished region of DCR.
