摘 要: 对一种7075铝合金实心型材进行了热模拟试验研究,并对其组织及性能进行了分析测试.结果表明,在挤压温度380~400℃,固溶淬火温度480℃、保温时间2.5h,以及在120℃及保温时间24h的时效处理工艺条件下,7075铝合金实心型材的抗拉强度、屈服强度及延伸率分别达到635MPa,576MPa和8.5%. A solid profile of 7075 aluminum alloy was investigated through heat-simulation test, and also the microstructure and property of the profile were analyzed. The results show that the tensile strength, yield strength and elongation of the solid profile 7075 aluminum alloy can get to 635 MPa,576 MPa and 8.5)0 respectively, under the condition of extrusion temperature of 380-400℃ ,solid solution at 480 ℃ for 2.5 hours,and aging at 120 ℃ for 24 hours.
