What Is Cold Working or Work Hardening? - The Balance

Cold working can change the strength and hardness of metals. Cold working refers to the process of strengthening a metal by changing its shape without the use of heat. This process, also known as plastic deformation, involves strengthening a metal by changing its shape. This process is also known as plastic deformation or work hardening.

What is Cold Working? - Definition from Corrosionpedia

Cold working is the process of strengthening metals through plastic deformation. This is made possible through the dislocation movements that are produced within a material's crystal structure. This is a technique commonly used in non-brittle metals that have remarkably elevated melting points.

Cold Work & Annealing Process - Google Sites

Cold Working. A measure of how much cold work a material received is needed if an investigation into mechanical property change is desired. The change in cross-sectional area of a metal specimen that underwent cold work is one means of measurement. This measurement of cross-sectional area change is known as “percent cold work”.

Work hardening - Wikipedia

Work hardening. Applications include the heading of bolts and cap screws and the finishing of cold rolled steel. In cold forming, metal is formed at high speed and high pressure using tool steel or carbide dies. The cold working of the metal increases the hardness, yield strength, and tensile strength.

The most common type is cold rolling, in which the metal being worked is squeezed through narrow gaps between rotating metal rolls. The movement of the rolls compresses the material, causing deformation as moves it through the gap. Another method is cold forging, in which metal is shaped by forcing it into a die with a …
