摘要

作为一种常见的轻量化合金，铝合金被广泛应用在航空航天、汽车制造等领域，但疲劳性能始终制约着其应用。为了保证铝合金构件的耐久性和安全性，系统且深入地认识铝合金疲劳性能具有重要的意义。从铝合金疲劳性能机理入手，介绍了常见铝合金的疲劳性能及微观组织、外加载荷、环境等因素对铝合金疲劳性能的影响，并总结了合金化、热处理、表面强化技术等提升铝合金疲劳性能的方法，最后对铝合金疲劳性能的未来方向进行了展望。

Abstract

Aluminum alloys are widely used in aerospace

automobile manufacturing and other fields as a common lightweight alloy. The fatigue performance

however

always restricts the application of aluminum alloy. In order to ensure the durability and safety of structural parts of aluminum alloy

it is of great significance to understand the fatigue behavior of aluminum alloy in depth and systematically. The fatigue performance of common aluminum alloys was described from the fatigue performance mechanism of aluminum alloys. The effects of the microstructure

applied load

working environment on fatigue properties of aluminum alloys were expounded

and the methods to enhance the fatigue properties of aluminum alloys were summarized

including alloying

heat treatment and surface strengthening. Finally

the future tendency on aluminum alloy fatigue was prospected.
