文摘

Application of EMILI during welding 2205 Duplex stainless steel hindered the coarsening of δ grains in HTHAZ and promoted regeneration of γ. Welds made with simultaneous EMILI presented TPI values at the HTHAZ similar to those for BM. Welds made under 3, 12 and 15 mT presented a mass loss by anodic polarisation similar to that observed for the as-received BM. This behaviour is due to changes in the dynamics of microstructural evolution during welding with EMILI.
