摘要

本文介绍了工业铝镁合金在空气和3%NaCl水溶液中的腐蚀疲劳试验结果。疲劳曲线可以用Basquin方程和裂纹尖端的塑性变形模型来表征。结果表明，铝镁合金在低应力下的腐蚀疲劳失效主要是由点蚀和晶间腐蚀过程以及高应力下的塑性变形造成的。

Analysis of contributions of plastic deformation and intergranular corrosion to corrosion-fatigue failure of Al-Mg alloys

The article presents the results of corrosion-fatigue tests of industrial Al-Mg alloys were conducted in air and in a 3%NaCl aqueous solution. Fatigue curves can be characterized using the Basquin equation and the plastic deformation model at the crack tip. It has been demonstrated that the primary contributions to corrosion-fatigue failure in the Al-Mg alloys at low stresses are made by the process of pitting and intergranular corrosion, and by the plastic deformation at high stresses.
