Local fracture properties and dissimilar weld integrity in nuclear power plants

Guozhen WANG, Haitao WANG, Fuzhen XUAN, Shantung TU, Changjun LIU

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 3, Pages 283-290 doi: 10.1007/s11465-013-0250-1

Abstract:

In this paper, the local fracture properties in a Alloy52M dissimilar metal welded joint (DMWJ) betweenThe results show that the local fracture resistance in the DMWJ is determined by local fracture mechanismIf the local fracture properties could not be used for cracks in the heat affected zones (HAZs), interfaceand near interface zones, the use of the fracture properties ( -resistance curves) of base metals orTherefore, it is recommended to obtain and use local mechanical and fracture properties in the integrity
