摘要
通过对国内外轨道车辆用铝合金母材发展历史的介绍,结合国产化动车组产品的引进消化吸收,指出了目前国内动车组车辆所用的两种铝合金型材母材牌号7N01和6005A,对比分析此两种牌号铝合金的化学成分、力学性能、疲劳性能、焊接性能的相同点和不同点,分析了两种牌号铝合金在实际应用中存在的问题,并对后期的应用提出了相关建议。
The development of aluminum alloy used for railway vehicles at home and abroad was introduced.Combining the products in homemade MU which are introduced,digested and absorbed,aluminum alloy of 7N01 and 6005 A were used in MU in China.The chemical compositions,mechanical properties,fatigue property and weldability were compared between 7N01 and 6005 A Al alloys.Their problems in practical application were analyzed,and the corresponding suggestions were proposed for the application in the future.
