WebJul 9, 2014 · The first has to do with displacement of molecules within the material, and the second has to do with stress and strain. As the material is bent, the inner region of the bend is compressed while the outer region is stretched, so the molecular density is greater on the inside of the bend than on the outer surface. WebNov 20, 2024 · There are two main schools of thought for best practice: temper pass and stretcher level. The temper pass process, which occurs at a temper mill, involves the application of pressure to the metal. Picture two giant rolling pins that apply an extreme amount of pressure as they compress the plate or sheet, thus squeezing out the stress.
