What is the hardening of the tribes?
trunks is a process in which metals bent metals during mechanically. The truncation is a process that takes place in the crystal grille of the material. This form of hardening is useful for increasing metal strength that cannot be hardened by thermal treatment. However, many metals and alloys that can be harvested can also be hardened. The tribes, also called Work Charnides, can deliberately be applied as a process of hardening during a component formation or does not occur in unintentionally during machining or abnormal operation.
before the tension, the materials usually show evenly distributed crystalline structure without defect. When the material is subjected to mechanical voltage, microscopic defects are known as dislocations in the crystal structure. If stress continues, these dislocations spread and interact with each other and create new internal structures that resist further deflection. These formations - or attaching points - increase materials provide strength or abilityBo soft. One of the most common ways of deliberately initiate the trunk process is the cooling mold.
As mentioned above, trunks of strains may be desirable or undesirable. If hardening is a intended result, the work of colds or forming parts is one of the most effective ways to achieve it. This is particularly useful in the work of metals that cannot be hardened. These include low -carbon steel, aluminum and clean copper. When these metals are compressed, drawn, bent or hammer during formation, the voltage causes the formation of crystalline dislocations that solidify the material.
No undesirable hardening of the tension occurs when towing or soft materials are processed incorrectly or too bending during their work. If the part is exposed to excessively deep cuts during machining, the resulting voltage may cause crystalline dislocations with the resulting hardening. This disgustFlaining hardening can then prevent further machining or even damage the tool bits. When the towing parts are machined, the bits of tools should be carefully advanced to prevent the occurrence of an undesirable job assertion.
Metal parts, which are bends beyond their design parameters during normal work, can also experience a certain degree of hardening of the trunk. Small deflections within these parameters are easily absorbed by a material that returns to the original shape without any changes in its internal structure. However, when it bends above these limits, the process of dislocation creation begins and the material solidifies. This causes the resulting resistance to any bending, which may lead to a possible cracking or breaking part.
