| Abstract;Both of stress corrosion and exfoliation corrosion resistance of high strength 5083-H32 alloy joints by FSW were vastly improved in addition to high strength, comparison with that of conventional MIG butt joints. These stemmed from prevention of resolution of homogeneously dispersed .BETA. phases and remained subgrains due to lower temperature of FSW. Conventional MIG butt welding, in contrast, makes .BETA. phases decompose and precipitate on the newly formed grain boundary to depreciate corrosion resistance because of higher temperature than .BETA. phases solidus. FSW is expected to break fresh ground for 5083-H32 alloy plates for both passenger vessels and maritime structures. (author abst.) |
