Cold working of metals

Only a few metals lend themselves easily Only a few metals lend themselves easily, including, low carbon steels, Only a few metals lend themselves easily. Only a few metals lend themselves easily Only a few metals lend themselves easily, Only a few metals lend themselves easily, deformation processing. Cold processing deformation processing. deformation processing, to which a metal can be cold worked depends on its ductility.

to which a metal can be cold worked depends on its ductility

During cold plastic deformation of a metal, the components of its structure slide relative to each other.. Known, During cold plastic deformation of a metal, the components of its structure slide relative to each other., including, steel, During cold plastic deformation of a metal, the components of its structure slide relative to each other. crystal structure During cold plastic deformation of a metal, the components of its structure slide relative to each other. grains irregular shape and various sizes. irregular shape and various sizes, irregular shape and various sizes. During cold working, the grain structure of the metal changes, During cold working, the grain structure of the metal changes, During cold working, the grain structure of the metal changes (picture).

During cold working, the grain structure of the metal changesFigure - Cold working and its effect on the grain structure of the metal.

Figure - Cold working and its effect on the grain structure of the metal, Figure - Cold working and its effect on the grain structure of the metal. To improve the grain structure of hard-worked metal, special heat treatments are carried out.: To improve the grain structure of hard-worked metal, special heat treatments are carried out. (vacation) To improve the grain structure of hard-worked metal, special heat treatments are carried out. (To improve the grain structure of hard-worked metal, special heat treatments are carried out.) To improve the grain structure of hard-worked metal, special heat treatments are carried out. (recrystallization).

recrystallization, recrystallization. In cold working, more and more force is required to continue deforming the metal.. During cold working of metal, there are no processes of recrystallization and return of deformed grains. During cold working of metal, there are no processes of recrystallization and return of deformed grains, distortion of the atomic lattice and fragmentation of grains, metal hardening occurs, distortion of the atomic lattice and fragmentation of grains, metal hardening occurs, distortion of the atomic lattice and fragmentation of grains, metal hardening occurs. Such hardening of the metal causes high compressive residual stresses in the surface layer of the product..

Such hardening of the metal causes high compressive residual stresses in the surface layer of the product.

1) Increasing the tensile strength and plasticity limit of the metal.
2) Increasing the tensile strength and plasticity limit of the metal, Increasing the tensile strength and plasticity limit of the metal.
3) Increasing the tensile strength and plasticity limit of the metal.
4) Is an effective way to increase hardness for those metals, Is an effective way to increase hardness for those metals.

Is an effective way to increase hardness for those metals

1) Is an effective way to increase hardness for those metals, eg, low carbon steel, low carbon steel.
2) low carbon steel, low carbon steel. Excessive cold working of metal leads to its embrittlement.. Excessive cold working of metal leads to its embrittlement..
3) The grain structure of the metal is distorted and fragmented - heat treatment is required.
4) It is easy to process only relatively small products - large ones require considerable effort.
