“…Structural steels with heavy thickness are commonly used in complex constructions, such as offshore oil platforms, large-scale bridges and so on [1][2][3], which usually operate in low-temperature environments. To meet the safety requirements [4][5][6], high strength as well as excellent toughness are necessary for heavy structural steels. It has been reported that very fine and homogeneous grains are beneficial for simultaneously improving strength and toughness.…”

The effect of Ti microalloying on the precipitation of NbC particles in Nb-microalloyed and Nb-Ti-microalloyed steels was investigated by scanning transmission electron microscopy. The experimental results illustrate that NbC precipitates tend to be formed via a conventional “nucleation and growth” mechanism in Ti-free steel, while the particles would be precipitated as a complex form of TiN cuboid core and NbC hemispherical cap in Ti-Nb-microalloyed steel with 0.009 wt.% Ti and 0.0046 wt.% N. Ti microalloying contributed to the refinement of the precipitate size, and an enhancement of the volume fraction of NbC particles was also found based on the experimental observations.
