| 摘 要： | 采用电磁铸造技术和普通连续铸造技术铸造了2024变形铝合金，采用光学显微镜和扫描电镜分析了其显微组织，而且对其进行了固溶处理加人工时效。结果表明电磁铸造锭内部组织细小均匀，有高的硬度和良好的疲劳性能，电磁铸造试样的硬度大约是普通连续铸造铸坯的2倍，疲劳性能是普通连续铸造铸坯的3倍。电磁铸造铸坯还有良好的耐磨性，磨损失重量是普通连续铸造的一半。 |
| 关 键 词： | 电磁铸造 连续铸造 2024铝合金 性能 显微组织 硬度 耐磨性 疲劳 |

| Abstract: | The 2024 aluminum alloys made by EMC and DCC were analyzed by optical microscope and scanning electron microscope, T6 treatment was given to investigate the mechanical properties such as hardness, wear resistance and fatigue It is shown that EMC ingots have fine and uniform grain structure, which make the EMC ingots have high hardness and good fatigue The hardness of EMC specimens is two times as high as DCC ones and the fatigue three times in as cast state The EMC specimens also expresses an excellent characteristic in wear resistance; the weight loss is only a half of DCC specimens |
| Keywords: | electromagnetic casting microstructure hardness wear resistance fatigue |
