Tempering (metallurgy) - Wikipedia

Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.

Residual Welding Stress - an overview ScienceDirect

One issue that should be mentioned is the fact that residual stresses can change as a result of shakedown from subsequent applied loading (McClung, 2007).Indeed, relaxation of tensile welding-induced residual stress in direct proportion to the magnitude of the applied stress has been observed following the application of a single tensile stress cycle (Iida and Takanashi, 1997).
