Cu对8030铝合金组织与性能的影响
|
摘要
利用金相显微镜、扫描电镜、万能试验机和导电仪等分析测试了不同Cu含量的8030铝合金的显微组织和性能。结果表明,随着Cu含量增加,8030铝合金的抗拉强度有所提高,伸长率下降,电导率上升。
The microstructure and properties of 8030 aluminum alloy with different Cu contents were analyzed by optical microscopy,scanning electron microscopy,universal testing machine and electric conductivity meter.The results show that with the increase of Cu content,the tensile strength and conductivity of the aluminum alloy increases,whereas the elongation decreases.
