| 摘 要： | 采用不同熔体处理工艺获得3种不同冶金质量的3003铝合金,通过Gleeble-1500热模拟试验机对3003铝合金进行变形温度为300℃~500℃,应变速率为0.01s-1~10s-1高温等温压缩实验。结果表明,3003铝合金具有正的应变速率敏感性,热变形激活能Q与含杂量H呈线性关系,经高效综合处理的3003铝合金热变形激活能最低为174.62kJ.mol-1,有利于材料热塑性变形。采用加工硬化率计算不同熔体处理的3003铝合金的临界应变值,获得了经不同熔体处理的3003铝合金发生动态再结晶的临界条件。 |
| 关 键 词： | 3003铝合金 熔体处理 热变形激活能 动态再结晶 临界应变 |

| Abstract: | 3003 Al alloys with different metallurgical quality were obtained by different melt-treatment methods,which were deformed by isothermal compression in the range of deformation temperature 300℃~500℃ at strain rate 0.01s-1~10.0s-1 with Gleeble-1500 thermal simulator.The results show that the material is sensitive to positive strain rate,the linear relationship between the hot deformation activation energy Q and inclusion content H is Q=35.62H+171.58,and the activation energy of 3003 Al alloy prepared by high melt-treatment is the lowest 174.62kJ·mol-1 which is beneficial to the hot plastic deformation of material.The critical strain of 3003 Al alloy prepared by different melt-treatment methods were calculated with work hardening rate,and the critical conditions to predict the dynamic recrystallization occurrence for the 3003 Al alloys prepared by different melt-treatment methods were obtained. |
| Keywords: | 3003 Al alloy melt-treatment hot deformation activation energy dynamic recrystallization critical strain |
