摘　　要：本文对304不锈钢U形波纹管进行疲劳性能试验后,使用断口分析、金相分析等手段对试样进行分析。结果表明:疲劳断裂的波纹管裂纹在内部随机产生;胀形后的波纹管晶粒内有滑移带等缺陷的生成,是导致疲劳断裂发生的主要原因。In this paper, the fatigue performance of 304 stainless steel U bellows was tested, and the samples were analyzed by means of fracture analysis and metallographic analysis. The results show that the crack in the fatigue fracture is randomly generated internally, and the generation of defects such as the slip band in the grain of the bellows is the main reason for the occurrence of fatigue fracture.
