Distortion of components from heating can also arise from the relief of residual internal stresses. When mill products are produced, they are straightened or flattened after annealing. These residual stresses are what keep them straight and flat. There may also be residual stresses from fabrication.See all

Controlling Distortion in Heat Treatment Through Press ...

Press quenching is a specialized quenching technique that may be utilized to minimize the distortion of complex geometrical components during heat treatment1. Distortion is routinely encountered in industrial heat treating operations, and is an especially important consideration where high accuracy, precision components are concerned. It can result from a wide variety of independent contributing factors. In press quenching thes…See more on thermalprocessing.comsp.info Weld Distortion - Welders, Welding Wire, Welding …Weld Distortion. Beginning welders and even those that are more experienced commonly struggle with the problem of weld distortion, (warping of the base plate caused by heat from the welding arc). Distortion is troublesome for a number of reasons, but one of the most critical is the potential creation of a weld that is not structurally sound.sp.info A comparative study on determination method of heat Jun 01,2009·The distortion control of heat-treated steel parts is a main consideration when dealing with hardening by quenching process.Before implementing this heat treating process,prediction of distortion is necessary to be done by experiment and computer simulation for determining a quenching technique which gives the smaller distortion.sp.info (PDF) Heat Treatment of Gearsdistortion during the heat treatment and quenching of gears,and provide some insight into proper corrective action to correct distortion and high residual stresses during quenching.
