摘要
Abstract
A7N01 aluminum alloys have a wide application in the field of high speed train,and welding is the main joining method to join the aluminum alloys.It is noted that 90％ fracture of the weld joints enduring dynamic load is the fatigue fracture.Fatigue property of the A7N01 aluminum alloy joints is investigated in this paper.The porosity is found in the weld,the porosity increased with the increase of the thickness of the joints,which caused the fatigue strength of the joints decreased.关键词
