摘　　要：提高轻质高强铝合金在汽车领域的使用量是实现汽车轻量化的有效途径之一,但在实际生产中,由于应力和服役环境的共同作用,铝合金部件容易发生腐蚀开裂进而失效的现象。从冶金因素、环境因素、应力因素等3方面综述了近年来国内外对高强铝合金材料应力腐蚀开裂敏感性的研究现状,并对其发展方向进行展望。It is one of the effective ways to achieve lightweight vehicles by increasing the usage of lightweight and high-strength aluminum alloys in the automotive field.However,due to the combined effects of stress and service environment,aluminum alloys are prone to corrosion cracking and failure in actual production.The current research status on the stress corrosion cracking susceptibility of high-strength aluminum alloy materials at home and abroad in recent years was reviewed from three aspects,namely metallurgical factors,environmental factors and stress factors.In addition,the development direction was prospected.
