摘要

在本研究中，研究了不同时效处理对6151铝合金板材硬化性能的影响。根据研究结果，与固溶处理后的自然时效相比，预时效片材的人工时效硬化响应明显更强。在人工时效阶段，120℃预时效处理比80℃和100℃预时效产生更显著的强化效果。人工时间越长，硬度值越高。当人工时效温度达到200℃时，达到峰值时效所需的时间最短，并且在过时效状态下软化的发生是明显的。当人工老化温度为200℃时，软化效果变得更加显著。自然老化可以抑制人工老化的强化作用。随着自然时效的延长，人工时效的硬化作用逐渐减弱。

Microstructure and Properties of 6 Series Aluminum Alloy Under Different Aging Treatment Systems

In the present study, an investigation is conducted into the effect of different aging treatments on the hardening properties of the 6151 aluminum alloy sheet. According to the research results, the artificial aging hardening response of the pre-aging sheet is significantly stronger compared to natural aging after the solution treatment. In the stage of artificial aging, 120 oC pre-aging treatment produces a more significant strengthening effect than 80 oC and 100 oC pre-aging treatment. The longer the artificial time, the higher the hardness value. When the artificial aging temperature reaches 200 oC, the time taken to achieve peak aging is the shortest, and the occurrence of softening is evident in the over-aged state. When the artificial aging temperature is 200 oC, the softening effect becomes more significant. Natural aging can inhibit the strengthening effect of artificial aging. With the extension of natural aging, the hardening effect of artificial aging diminishes gradually.
