在过去的10年里,由于对熔融冶金(铸锭冶金)技术进行了改进,开展了新合金研究及应用新的机械热处理法。在铝合金领域里取得了显著成就,特别是静态机械性能得到明显的提高。但疲劳性能,特别是带缺口的疲劳强度方面,改进并不明显。然而这些性能对保证材料的强度是很重要的,而且使材料在飞机上应用的可能性明显增加。用于飞机上的铝部件在强度
In the past 10 years, due to the improvement of the technology of molten metallurgy (ingot metallurgy), new alloy research and application of new mechanical heat treatment methods have been carried out. Significant achievements have been made in the field of aluminum alloys, and in particular static mechanical properties have been significantly improved. However, the improvement in fatigue performance, especially in the case of notched fatigue, is not obvious. However, these properties are important to ensure the strength of the material and significantly increase the likelihood that the material will be used on the aircraft. Aluminum parts for use on aircraft in strength
