| 摘 要： | 对截面为3 mm×3mm的16Mn钢试件在空气和3.5%NaCl溶液中分别进行疲劳试验,获得了S-N曲线,并对疲劳试样表面和断口形貌进行了观察.结果表明:与空气相比,3.5%NaCl腐蚀溶液使16Mn钢的疲劳强度显著降低;在空气中疲劳试样只有一个萌生于试样表面基体的裂纹源,而在3.5%NaCl溶液中一般有多个裂纹源,而... |

| Abstract: | The fatigue behavior of 16Mn steel in air and 3.5% NaCl solution is studied by the fatigue tests.The S-N curves are obtained and the observations of specimen surfaces and fatigue fractographs are made.The results show that the fatigue strength of 16Mn steel in 3.5% NaCl solution is much lower than that in air.Fatigue cracks in air are initiated from the matrix of surface,while most of fatigue cracks in3.5% NaCl solution are initiated from pits.The typical feature of the fatigue crack propagation region in a... |
