Metal Stress Relieving - ThermTech
WebStress relief. Residual stresses can be relieved by plastically deforming the material in a controlled manner (1-3% [ASM Handbook, 1995]) through either a compressive (designated Tx52) or tensile (designated Tx51) loading. This technique is used extensively on open die forgings with only minimal effects on the final mechanical properties of the ... http://alcotec.com/us/en/education/knowledge/techknowledge/understanding-the-alloys-of-aluminum.cfm childrens outdoor swings
