Abstract In this paper, the IHTC evolutions between a hot AA6082 specimen and cold P20 tools were quantitatively studied as a function of contact pressure, specimen thickness and lubricant, using the inverse FE simulation method. A novel interactive model was developed to predict IHTC evolutions with diminutions of different lubricants as a function of sliding distance (or time) at different contact pressures and sliding speeds. It was deduced that the interaction between the lubricant and the IHTC consists of three stages; namely stage I (excessive stage), in which the lubricant is applied excessively and the IHTC is plateaued, stage II (consumption stage), in which the lubricant diminishes during sliding and the IHTC decreases rapidly, and stage III (breakdown stage), in which lubricant breakdown occurs and the IHTC is equal to its values under dry conditions.

AA6082铝合金热冲压过程中润滑剂对IHTC的影响：实验和建模研究

摘要 在本文中，使用逆有限元模拟方法，作为接触压力、试样厚度和润滑剂的函数，定量研究了热 AA6082 试样和冷 P20 工具之间的 IHTC 演变。开发了一种新颖的交互模型来预测 IHTC 演变，其中不同润滑剂的减少是不同接触压力和滑动速度下滑动距离（或时间）的函数。据推断，润滑剂与 IHTC 之间的相互作用包括三个阶段；即I阶段（过量阶段），润滑剂过量使用，IHTC趋于稳定；II阶段（消耗阶段），滑动时润滑剂减少，IHTC迅速下降；III阶段（故障阶段），
