The evolution of residual stress during thermomechanical treatment and its underlying mechanism are investigated. Further, two new mechanisms, precipitation plasticity mechanism and precipitation induced creep mechanism, which have important effects on residual stress are proposed. By using the mechanism proposed in this article number 1900421 by Yazheng Liu and co‐worker, low temperature regulation of residual stress can be realized.
