The higher t<jats:sub>8/5</jats:sub> leads to the increased content of intragranular ferrite (IGF). Meanwhile, the prior austenite grain size (PAGS) progressively increases from 56 ± 6.0 μm to 148 ± 9.9 μm as t<jats:sub>8/5</jats:sub> increases from 30 s to 180 s.

Moreover, the impact toughness decreases as t<jats:sub>8/5</jats:sub> increases from 30 s to 90 s caused by the increased PAGS and GB content, and then sharply increases with t<jats:sub>8/5</jats:sub> exceeding 90 s due to the increased formation of IGF, especially IAF. Furthermore, the high nitrogen content accelerates V(C,N) precipitation, which not only inhibits the coarsening of prior austenite grains, but promotes the formation of IGF, resulting in the increased number of HAGBs and raising impact toughness.</jats:p> Significant Influence of Welding Heat Input on the Microstructural Characteristics and Mechanical Properties of the Simulated CGHAZ in High Nitrogen V-Alloyed Steel High Temperature Materials and Processes
