摘要
采用不同的固溶温度和时效温度对7A04-0.8Sr新型铝合金飞轮进行热处理试验,并分别在25℃室温和300℃高温环境下对试样进行了耐磨损性能的测试与分析。结果表明,随固溶温度从430℃增加到510℃或时效温度从120℃增加到200℃,新型飞轮的耐磨损性能均先提高后下降。新型铝合金飞轮的固溶温度和时效温度分别优选为500℃和190℃。
Innovated 7A04-0.8Sr aluminum alloy flywheels were heat treated with various solid solution temperatures and aging temperatures. And the wear resistance of the flywheels was tested and analyzed at 25℃ and 300℃. The results show that the wear resistance of new flywheels first increases and then decreases with the solid solution temperature increasing from 430℃ to 510℃ or aging temperature from 120℃ to 200℃. The optimized solid solution temperature and aging temperature are 500℃ and 190℃, respectively.
