Talk about the thermal deformation conditions of aluminum plate

Thermal deformation conditions of aluminum sheet the thermal deformation conditions of aluminum sheet include deformation temperature, deformation speed and thermal deformation. High temperature deformation heat treatment of the same alloy under different thermal deformation conditions will have different effects. The higher the deformation temperature of aluminum plate (the plastic zone of the alloy shall be considered when selecting the temperature).

The easier the dynamic recovery is, the less energy is stored in the metal, and the more difficult it is to recrystallize. Therefore, increasing the deformation temperature is beneficial to high-temperature thermomechanical treatment. The faster the deformation speed of aluminum plate, the more difficult the dislocation combination process is, which affects the composition of dynamic recovery process.

Therefore, in order to improve the effect of high temperature thermomechanical treatment. The deformation speed shall be reduced. In all conventional pressure machining methods, the speed of extrusion deformation is relatively low, and it is easier to complete high-temperature thermomechanical treatment by extrusion. Under the same deformation temperature and deformation speed.

The greater the degree of deformation. The more deformation energy is stored in the metal, which is beneficial to the recrystallization process, so it has an adverse impact on the high-temperature thermomechanical treatment. In short, in order to complete the high-temperature thermomechanical treatment, it is necessary to adopt a reasonable aluminum plate thermal deformation process.
