摘要
介绍了轨道车辆用变形铝合金的种类、化学成分、合金元素作用、热处理特点、力学性能,以及高速列车机车车轴齿轮箱和电机齿轮箱箱体所用的ZLAlSi7Mg铸造铝合金的化学成分和力学性能。
The alloy types, chemical compositions, function of alloying elements, features ot heat-treatment, mechanical properties of the wrought aluminium alloys have been introduced. The chemical compositions and mechanical properties of ZLA1Si7Mg cast aluminum alloy used for gearboxes of shafts and electrical motors of the high velocity locomotives, and the ap- plication situation in high speed track vehicle have been introduced as well.
