Abstract
null null The effect of tungsten inert gas welding and subsequent post-weld heat treatment on the microstructure evolution and pitting corrosion behavior of duplex stainless steel UNS S31803 was investigated. Detailed microstructure examination demonstrates that ferrite presents higher volume fraction and is easier to suffer attack of pitting corrosion than austenite in the welded zone of as-welded metal. After post-weld heat treatment, the...
