Microstructure and stress corrosion cracking of the fusion boundary region in an alloy 182-A533B low alloy steel dissimilar weld joint

► High-angle misorientation at FB, type-II and type-I boundaries. ► Highest residual strain and hardness in the zone between FB and type-II boundary. ► Type-II and type-I boundaries had lower resistance to SCC growth than the FB. ► Crack growth blunted by pitting at the FB. ► Reactivation of crack g...
