| Abstract: | The fracture failure of Sn-brass pipe steam condenser used in power plant is analyzed by chemical analysis,XRD analysis techniques,Scanning Electrical Microscopy(SEM) and Energy Dispersive Spectrum(EDS).The results show that stress corrosion and corrosion fatigue are the main causes for the fracture failure.According to the analysis,some significant precautionary measures are suggested. |
