对变形毛坏的整个范围和塑性区温度进行研究,是有现实意义的,因为与主要工艺参数有关系的温度变化的规律性是选择最好的温度速度制度的先决条例,从而可确定整个生产的经济性和设备的生产率。温度场的分析工作〔1、2〕是极据许多的简单假设进行的,而最终计算的关系式对实际应用是复杂的。测量温度的主要困难是,在变形过程中塑性区的每个点的温度和压力都有所改变,而点的本身且与金属流一起移动。因为温度过热高于固相线是铝合金机械性能损失的原因,所以
It is of practical importance to study the entire range of texturing spoilage and the temperature of the plastic zone since the regularity of the temperature changes in relation to the main process parameters is a prerequisite for selecting the best temperature speed system and thus the overall production The economy and equipment productivity. The analysis of the temperature field [1, 2] is based on many simple hypotheses, and the final calculated relation is complicated for practical use. The main difficulty in measuring temperature is that the temperature and pressure at each point of the plastic zone change during deformation and the point itself moves with the metal flow. Because the temperature is higher than the solidus overheating aluminum mechanical properties of the reasons for the loss
