Cold Work is a quality imparted on a material as a result of plastic deformation at low to moderate temperatures (typically <0.5 Tm). Such deformation increases the concentration of dislocations which may subsequently form low-angle grain boundaries surrounding sub-grains. Cold work generally results in a higher yield strength as a result of the increased number of dislocations and the Hall-Petch effect of the sub-grains. However, there is a simultaneous decrease in the ductility. The effects of cold working may be removed by annealing the material at high temperatures where recovery and r ...
Cold work - Elastic and Plastic Deformation.
Cold work occurs as a consequence of plastic deformation. A discussion of elastic deformation and plastic deformation must first be made. The discussion mostly involves metals, especially steels, which are well studied. The tensile test is a popular method to study deformation mechanisms.
Elastic deformation is deforming a material only slightly with a minimum-smoothly-applied force. This only slightly stretches atomic bonds in the material away from their equil ...
