Abstract
Previous research has suggested that significant improvement in ductility-dip cracking resistance of ERNiCrFe-7 weld metal can be obtained if sec-ond phase precipitation during welding is optimized with some carbide and nitride forming element additions. Therefore, a theoretical and experimen-tal work has been conducted to address the effect of Nb and Ti additions to the precipitation of second-phase particles during welding of a ERNiCrFe-7-like alloy. The critical precipitation temperatures, phase fractions and atomic partitioning in the microstructure were among the factors analyzed in the light of DDC resistance improvement.
