Work Hardening Sheet Metal

The asset is that the areas where dies have deformed sheet metal from its original flat state provide much of the necessary panel strength in body design.

Work hardening sheet metal.

As it moves through the rollers and is compressed the metal grains are deformed. The breakage is not due to bad metal sheet it has just been work hardened by too much movement. Sometimes you can break a headpin or a piece of wire when repeatedly trying to get a coil just right. The answer is work hardening.

The phenomenon of work hardening is critical in the design and fabrication of sheet metal automobile panels. It is both a problem for and an asset to anyone who has to repair sheet metal. Work hardening in metallurgy increase in hardness of a metal induced deliberately or accidentally by hammering rolling drawing or other physical processes. Many non brittle metals with a reasonably high melting.

Work hardening also known as strain hardening is the strengthening of a metal or polymer by plastic deformation work hardening may be desirable undesirable or inconsequential depending on the context. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. Although the first few deformations imposed on metal by such treatment weaken it its strength is increased by continued deformations. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material.

Cold rolling is the most common method of work hardening. Many jewelry makers have felt the effects of work hardening.
