鋁板的熱變形條件包括變形溫度、變形速度及熱變形量。同一合金在不同熱變形條件下進行高溫變形熱處理將有不同的效果。
The thermal deformation conditions of aluminum plate 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.
1、鋁板變形溫度愈高(選擇溫度時須考慮該合金的塑性區),動態回復愈易進行，金屬中的儲能愈少，再結晶愈困難，因而提高變形溫度對高溫形變熱處理有利。
1. The higher the deformation temperature of aluminum plate (the plastic zone of the alloy must 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.

2、鋁板變形速度愈快，位錯的組合過程愈難進行，影響動態回復過程中亞晶的形成。因而為了提高高溫形變熱處理效果，應降低變形速度。在所有常規壓力加工方法中，擠壓變形的速度相對較低，采用擠壓更易實現高溫形變熱處理。在同樣的變形溫度及變形速度條件下，變形程度愈大，金屬中變形儲能愈多，對再結晶過程有利，因而對高溫形變熱處理有不利的影響。
2. The faster the deformation speed of aluminum plate, the more difficult the dislocation combination process is, which affects the formation of subgrain in the dynamic recovery process. Therefore, in order to improve the effect of high temperature thermomechanical treatment, the deformation speed should be reduced. In all conventional pressure machining methods, the speed of extrusion deformation is relatively low, and it is easier to realize high-temperature thermomechanical treatment by extrusion. Under the same deformation temperature and deformation speed, the greater the deformation degree is, the more deformation energy is stored in the metal, which is beneficial to the recrystallization process, so it has an adverse effect on high-temperature thermomechanical treatment.
總之，為實現高溫形變熱處理，需要采用合理的鋁板熱變形工藝。
In short, in order to realize high temperature thermomechanical treatment, it is necessary to adopt reasonable aluminum plate thermal deformation process.
