Influence of load on sliding tribology of C/C composite with 40Cr steel couple coated by Cr...: With the 40Cr steel couple coated by Cr, the sliding tribology behavior of two kinds of C/C composites with different matrix was tested using a M2000 wear tester. The results show that with the increasing......
SUPERPLASTICITY OF A WATER-QUENCHED AND TEMPERED 40Cr STEEL L.J Shi1,L.Cai1,X.J.XU1,G.L.Liu1,X.N.Cheng1 (1.School of Mechanical Engineering, Jiangsu University, Jiangsu 212013, China) Abstract:The superplastic deformation characteristics, of commercial 40Cr (i.e., 5140) steel that was water-quenched only 1 times and subsequent high-temperature tempered, were investigated.The results showed......
Electrochemical techniques for monitoring stress corrosion cracking of Type 40Cr steel in acidified chloride solution AN Li-juan(安丽娟), LI Qing-fen(李庆芬) College of Material Science and Chemical... steel specimens exposed to the acidified chloride solution at ambient. To test these two techniques, slow strain rate tensile (SSRT) tests were performed with 40Cr specimen in the identical corrosive......
环境介质对40Cr结构钢高周和超高周疲劳行为的影响 洪友士1,钱桂安1 (1.中国科学院力学研究所非线性力学国家重点实验室,北京,100190) 摘要:选用40Cr结构钢,分别在空气,水和3.5%NaCl水溶液中进行旋转弯曲疲劳实验,研究环境介质对该结构钢高周和超高周疲劳特性的影响.结果表明,40Cr钢在水环境中的疲劳强度比在空气中明显降低;在3.5%NaCl水溶液环境中的疲劳强度比在水中低.断面观察显示,在水和3.5%NaCl水溶液中,疲劳裂纹多源萌生;在稳态扩展阶段,裂纹沿品界扩展并存在广泛分布的沿晶二次裂纹. 关键词:40Cr结构钢; 超高埘疲劳; 环境介质; 疲劳强度; 疲劳裂纹萌生; structural steel 40Cr; very high-cycle fatigue; environmental media; fatigue strength; fatigue......
