对地铁列车车体用 60 0 5A铝合金进行了在线挤压淬火正交实验和透射电镜分析 ,研究了挤压温度、挤压速度、淬火方式对合金力学性能的影响。结果表明 :淬火方式对合金性能的影响最大 ,水淬可使合金获得高的力学性能 ;提高挤压温度和挤压速度也可在一定程度上提高合金力学性能。透射电镜分析表明 ,在线挤压淬火工艺对合金力学性能的影响实质上与 β'强化相的数量、大小。
The effects of the extrusion temperature, extrusion speed, quenching way on the mechanical properties of 6005A alloys were studied by the on line extrusion orthogonal experiments and transmitted electron microscopic analysis. The results show that quenching way has the most obvious effect on the mechanical properties of the alloys. Water quenching can improve the mechanical properties of the alloys more. Improving extrusion temperature and extrusion speed can also do to a certain extent. Transmission electron microscopic analysis shows that the effect of on line extrusion quenching technique on the mechanical properties of the alloy is closely related to the amounts, the size and the distribution of the β' precipitated phase.
